Tips & Tricks: 3 Tips to Mount MTB Tubeless Tires with a Handpump

Tips and Tricks Handpump Mounting MTB Tubeless Tires

Whether you’re on a trip, or helping someone out at the trailhead (or helping yourself occasionally…) some quick tips will help you successfully to Mount MTB Tubeless Tires with a Handpump. Check out this quick video from BikeCo.com or glance through the short write up below.

Mount MTB Tubeless Tires with a Handpump

Tip One: How Much Air How Fast?

The first tip to mounting a tire easily, whether with a handpump or a compressor, is to ensure the most volume of air is pushed easily into the tire.

For this I love valve stems that have a removable core.

By removing the core I greatly increase the volume of air I can get quickly into the tire. This will notably help to bead the tire onto the rim.

Tip Two: Grip.

The next step is to get a grip that allows you to easily hold the pump head onto the valve while having your hand wrapped around the tire.

Mount MTB Tubeless Tires with a Handpump Grip the Pump and Tire

Position your hand so two fingers can hold the pump head while you wrap your thumb onto the top of the tire. With this grip you’ll have a good grip for the next step.

Mount MTB Tubeless Tires with a Handpump Bounce and Squeeze

Tip Three: Bounce and Rotate.

While pumping bounce the tire and squeeze with your hand.

The bouncing and squeeze will help reduce the volume inside the tire. This also increases the PSI and to help bead the tire.

This method tends to work quickly. If you’re struggling take a look and make sure there’s nothing obviously wrong.

Quick list of things that are SUPER annoying if you’ve tried this for a while… Are both beads of the tire on the same side of the air valve (so your pumping goes straight into the atmosphere)? Is a bead sitting on the valve?

Depending on the tire it may help to rotate as you bounce it. This provides a bit more pressure in different spots of the tire.

Hopefully this quick video and writeup help you Mount MTB Tubeless Tires with a Handpump!

Nukeproof Ride Review: Mega 290 & Reactor 290

Nukeproof Ride Review Mega 290 and Reactor 290. Reactor and Mega with Riders looking at bikes on fire road in cloud.

Mike, Tracy and I had a chance to take out two of the most popular bikes in the Nukeproof lineup.

While we didn’t have the most cooperative SoCal June weather we defined what we liked about the spec and how the Nukeproof Mega 290 and Reactor 290 ride on trail.

Mega 290 & Reactor 290: Nukeproof Ride Review

Nukeproof Mega 290 Carbon bike Review on The Luge

In this Nukeproof review we’ll glance at the spec of both the Mega 290 Factory and the Reactor 290 Elite builds.

Where do the bikes stack up in the BikeCo lineup? What are some variants we’d see on our personal bikes?

Later we’ll get into HOW the bikes ride and the overall Nukeproof trail personality.

Nukeproof Build Kits

Learn more about the Nukeproof Factory and Elite Build Kits with these tabs or keep reading for more about the Reactor 290 and the Mega 290’s trail personality.

Nukeproof Mega 290 Carbon Factory Spec Highlights

The Nukeproof Mega 290 Carbon Factory build is essentially an XT bike with FOX Factory Suspension.

The Mega 290 has 160mm of rear travel paired to a 170mm fork and is a confident Enduro or All Mountain bike.

The FOX Factory fork and shock both provide adjustment through PSI, volume spacing, high and low speed rebound as well as high and low speed compression settings. This gives the bike a wide range of tuning options for any rider size.

Shimano’s XT drivetrain and brakes with 203mm rotors front and rear perform as you’d expect.

Spec’d with Double Down tires front and rear it’s set for aggressive riding from the get-go.

DT Swiss EX1700 wheels provide a great platform to mount an Enduro / All Mountain appropriate tire selection from around 2.3″ or 2.4″ to 2.5″ or 2.6″ if you prefer.

Mega 290 Factory Build Thoughts

While the three of us tend to build very different bikes for our personal quivers we actually had a lot of parallel thoughts on the Mega 290 Factory build.

This is a bike that’s spec’d nicely from the factory. We each had a short list of what we’d probably change if we were going to make this bike our own and really we only had a single build “issue”: the saddle. It’s slippery! Now, you can see in the images we were riding in a low cloud which probably made everything a little more slippery – but everyone noted that the saddle would be the first thing off the bike for any of us.

Mega 290 Factory Spec Upgrades

So what are some personal upgrade or swap ideas for the Nukeproof? Well take this with a grain of salt as the three of us have more years riding then we’d like to admit as well as enough gray hair to be really particular (note Mike’s jersey…), so our upgrades or swaps would all be pretty personal preference things.

Each of us have a preferred brake setup that would go on the bike but as far as spec brakes the Shimano XT are absolutely workable.

All of us have a go to cockpit. Most likely we’d all gravitate to higher rise carbon bars and I would have to have my preferred grip too.

Tracy likes the Double Down tires front and rear. I might go to my EXO+ setup or at least the EXO+ in the front with a DHF for maybe a touch faster rolling setup.

Mike’s finally entry on this was a GX AXS derailluer, he rides wireless drivetrains and was convincing us how lowering the work load on my thumbs would improve my climbing (not much could make my climbing too much worse compared to these guys haha)

If you want to go through the notes on a Nukeproof Elite build (basically an SLX bike) click over to the Reactor 290 tab for more details.

Nukeproof Reactor 290 Elite Spec Review. Reactor 290 climbing on trail in low cloud.

Nukeproof Reactor 290 Carbon Elite Build Highlights

The Reactor 290 Elite build features Shimano SLX drivetrain and brakes as well as FOX Performance Elite suspension giving it a very credible setup. The Reactor is a 130mm travel frame paired to a 150mm fork for a nice Trail and Light / Medium Terrain Enduro bike.

The Performance Elite suspension features the more advanced dampers with improved compression control similar to the FOX Factory options, just without the Kashima coating.

Shimano’s SLX bits feature excellent performance in a bit more cost-conscious at a small weight penalty compared to the XT spec of the Factory builds.

Reactor 290 Elite Spec Review

Our conversation on the Reactor 290 Elite spec had a handful of tangents.

Before we get too deep into what we would have done to “make it ours” so to speak let’s take a glance at the SLX buyer’s opinion.

This is a nice SLX spec. If you didn’t have an established go to for say, like almost every bit on your bike there’s little on this bike that really glares at you. Except the slippery seat. It’s slippery.

Beyond the tires, brakes, cockpit setup preference changes (like we touched on with the Mega 290 Factory build in the other tab) the only other bits that stand out for consideration of upgrade are the wheels and maybe the seatpost.

We started debating about if you were to throw a little bit more cash at this bike where would it go?

Wheels play a big part in a bikes personality so we tossed around ideas on well if we did this, or that to this bike but when we looked at the price consideration it put us into the neighborhood of the Factory build with improved wheels as well as the XT drivetrain and brakes.

And frankly – that’s how models should be spec’d. I like that Nukeproof has a relatively closely grouped build price point and that you can see the value in all of the available models.

Devil’s advocate though: how mean would the Elite look with some carbon hoops on it and new hubs?

So how did each of the Nukeproof bikes ride on trail?

Well as you’d expect, even though the Mega is a 160/170 bike and the Reactor a 130/150, they had some brand personality similarities when we compared notes.

Nukeproof Trail Personality

Nukeproof Sizing

Mike, Tracy and I are sort of close in height. Well, close enough that I can’t really think of who’s the tallest or shortest.

Each of our current personal bikes is a Large, albeit mine is a Mondraker Foxy so it’s a LONG large.

I’ve always been kind of between sizes at 6’1″ with long legs and arms. Lately I’ve been riding longer bikes and think it has been helping my lower back some – so I went with the XL Nukeproof Mega for our test ride.

Mike tends to ride Large although some bikes he may adjust depending on top tube length to keep him in a better position for his neck and back.

Tracy and I have traded bikes a lot over the years and generally we’re super close in setup. I think most of his personal bikes have been Large lately.

Once I jumped on it I had no doubts it was the right size. I never felt “lost” in it at all. In fact I kind of struggled to see how a 20mm shorter reach would have worked either. So I started giving Tracy a hard time about his Large selection. By the end of the ride he agreed that the XL would have been a nicer fit.

Mike rode the L Reactor 290 and seemed like he enjoyed the fit as its closer to his current quiver of bikes although the reach is a little shorter on the Nukeproof compared to other brands.

With almost all size bikes having room for longer dropper posts these days fit has become height as well as leg length and determining where you are on the “average” comparison of that.

I come in on the X-Large for height and the XX-Large for leg length according to Nukeproof. The XXL was going to be much to long for me but the XL was a good fit.

For taller riders, it makes sense that Nukeproof offers an XXL if the XL is a comfortable fit for me.

Nukeproof: On Trail

All of us enjoyed the miles on the Nukeproof Trail / Enduro models. Mike has actually ridden both of these bikes as well as the Giga and is a great resource for our team on the overall Nukeproof personality as well as the variations in their lineup.

Nukeproof Personality

As a disclaimer: we didn’t get the greatest conditions to really test these bikes.

But between the three of us, with a lot of years of doing this, there were a handful of things we agreed on about the Nukeproof trail performance.

Planted / Balanced Traction.

The bikes have a notable even balance on the front and rear wheels. In just about any reasonable riding position it was very easy to feel both wheels working together. You had to get way, way too far off the back to get the front end light. And I was uncomfortable getting far enough forward on the bars to have the rear wheel feel light (with one exception I’ll get into later hahaha…)

Along the same lines as being “planted” the bikes had an appropriate front to rear wheel feel climbing and descending.

I found the Mega 290 was a very forgiving bike to ride which became important on the descent as conditions turned more sloppy than any of us frequently ride.

Overall the Nukeproof rode most similarly to Ibis models we work with.

It might have had a little more “up and down” pedaling variation than my Yeti or Mondraker – but like the Ibis bike’s this motion directly equates to rear wheel traction so I didn’t find the bike sluggish to accelerate. It was well behaved even up some of the slippery climbing sections when the wheel was clawing up and over rocks or terrain shifts.

The Mega and Reactor had a little less “pop” than you might expect from a Yeti or Mondraker on trail. Some of that is from the suspension’s design but some of it is from the shock and fork setup as well.

I suspect with time I could have put more “pop” back into the Mega to have it ride closer to my preferred quicker out of corners, pumpy style bikes (but that style also tends to break free from traction faster too – so it’s really a personal setup preference at that point – read on for my detail notes and why understanding a review is helped by understanding the reviewer…)

Lively at Any Speed

Another aspect that’s important for bike performance, does the bike require a certain speed to come alive? Class leading bikes have good handling characteristics whether you’re riding at consumer, expert or even race paces.

The Nukeproof felt good in the range of speeds I was able to get it into. Some bikes struggle with sluggish handling at lower speeds or get nervous at high speeds. Bikes like Nukeproof, Ibis, Mondraker and Yeti put a lot of effort into their testing to ensure the bikes are playful and fun for the widest range of riders.

The Mega felt like it had more in the tank than I got close to giving it, but never felt like that school bus on a figure eight track that some “bigger” bikes parallel at lower speeds.

Nukeproof Reactor 290 Elite build review on trail downhill

Nukeproof Reactor 290: On Trail

Mike’s notes carry a lot of weight as he puts many miles on a variety of bikes. From Nukeproof, Ibis, Mondraker or Yeti he’s very familiar. So it was interesting to listen as he fit the Reactor 290 between other BikeCo models.

“The Reactor rides a like a little bigger than pretty burly built Ripley. You know the Ripley with the bigger fork and shock that we’ve done in the past.

I’d say maybe closer to the Ripmo even. Not quite as big as the Ripmo travel wise but the Reactor is closer to a ‘fast’ Ripmo setup more than a big ‘Ripley’ probably.

The Nukeproof suspension feels similar to the Ibis although it would take me a little bit to get the Nukeproof as precise as the bikes’ I’m comparing since I’ve had more time on them.

On the Reactor I felt confident that the bike would turn in and hold a line. It felt pretty good over the chunkier stuff but we were kind of going slower today because of conditions too.

For me, this is a very well equipped bike at the price.  The Elite build I rode had the Fox Grip 2 damper on it which is all you really need or want.
We see many “DTC” bikes come into the shop and the client needs to spend more money to get the bike in a rideable condition.  You could ride one of these off the floor and it is ready to go.  Comfortable and super competent for the price point”

Nukeproof Mega 290: On Trail

Tracy and I have ridden a lot of bikes, in a lot of terrain over the years. Generally we both gravitate to a similar model capacity even if we ride different brands. So it made sense that both of us wanted to test the Mega 290 out of the Nukeproof lineup.

Overall we had pretty similar trail notes. I’m going to go deeper into my thoughts a little later as there’s A LOT of things that you feel and have to take into account on a demo ride and I think it’s important to be transparent and realistic – you can get an idea of how the Nukeproof bikes behave from this review but there is so much range of adjustment available as well. Anyway – back to the quick takes on the Mega 290 On Trail.

Tracy had some good insight

“The bike didn’t feel twitchy or nervous. Even as the trail got slick I felt like I could hold the lines I wanted.

It pedaled like I would expect for a 160/170mm bike. It wasn’t a slow pedaling bike at all. Could be tough to tell given how sticky the ground was too. But with the road ride before the dirt I felt like it compared well with other bikes its size.

I never felt the bike get nervous at speed. Couldn’t tell with today’s conditions but it might have that Yeti personality where it loves more and more speed.”

I agreed with all of his notes after the ride especially the speed capacity. I was able to get the bike up to a lively pace in a couple of the areas that weren’t as soupy and the bike never gave me any indication that it wouldn’t like a little more.

Both of us noted that the Mega was quite notable at holding lines in both the dry and wet conditions. You’d roll the Mega into a corner, get that lean angle going and that bike just carved in.

With the setup I noted the bike would take a lot of weight input from your feet while keeping the front end planted.

Quick Conclusions: Nukeproof Riding Review

So what’s the quick take on the Nukeproof Mega 290 or the Nukeproof Reactor 290?

Well drawn from the combined notes we had really positive notes overall on both the bike’s spec and value as well as the on trail personalities.

Nukeproof Mega 290 Carbon Factory Review. Bike turning on trail.

The Mega and Reactor both feel well planted, confident and forgiving on trail. These aren’t bikes with knife edge personalities and even a pretty basic setup provided a really enjoyable ride.

Nukeproof bikes overall feel like they have a bit of “monster truck” in them, similar to Ibis bikes, and ride comfortably feeling maybe slightly “bigger” than they are.

I know I put the Mega into situations that it was well behaved in without requiring over the top theatrics or heroics from me as a rider.

Wondering how the Nukeproof might fit into your personal riding? Chat with a member of our sales team. They’re all versed with the class leading brands BikeCo works with: Ibis, Mondraker, Nukeproof and Yeti. Our staff is trained on where these brand’s personality is as well as what tuning options are available to modify a bike to your desired requirements.

Remember: class leading bikes, ones with not only the “right” geo (which has converged somewhat over the years) but also the RIGHT suspension and balance have a setup range. And it can be hard to really understand it from a demo ride.

Since I’ve bitched for so long about those doing reviews being more transparent about “what” and “how” they ride you can keep reading for more details on my ride and how experience allows a better understanding of what a bike is about and where it fits.

But first enjoy some pics of Mike and Tracy from our Nukeproof Ride Review on the Luge!

Reviewing the Reviewer

I’ve been pushing for a long time that reviewers give more personal insight to their experiences that go into a published review. So to wrap up this Nukeproof Ride Review I’d like to provide insight to what I thought, what my exact notes were, what I ride and how I come up with some of my conclusions during a review.

There are a handful of things that experience will help you quickly define and if you know how those are about to effect your ride you can more accurately speak to a bike MODEL and not a SETUP so to speak.

What Did I Notice in Setup?

Some of my notes on while I setup the Mega 290 would help me better understand what the bike WAS doing on trail and what it COULD do as well.

Mega 290 Ride Review Notes on Setup

Factory Suspension

Both the fork and shock were low on volume spacers for my preference. This means I used the compression settings to increase support that would be more finely tuned by increasing the ramp rate.

It’s a demo bike – the odds it would have a perfect package are low. Knowing that I was running more compression meant that I would forgive a little bit of potential harsh small bump compliance in the rear as well as initial support into corners.

Cockpit

First, I have bad hands and hate grips with outboard collars. It hurts my hands, messes with my ulnar nerve and causes numbness and pain up my arms. This bike had grips I didn’t like but I would try to run my hands further inboard than I usually do.

Bars were aluminum and 25mm rise with not a lot of stem spacers. I generally like to have larger rise handlebars and carbon (it makes a big difference in my hand and arm condition to ride with carbon bars)

Tires

Double Down Assegai front and Double Down DHR rear. An aggressive setup but appropriate for the bike. I typically run EXO+ DHF / DHR pairing so I knew that tire package would be a bit heavier than I’m used to.

Setup Forgiveness Based on Spec

Will it ride Harsh?

So based on the volume spacers, compression settings, grips and bars I knew I would potentially have to forgive some front end “harshness”. In other words, it would not be a fair fork test for sure if that’s what we were testing!

Luckily the fork was freshly serviced and overall it felt good. I think the oil and seals being new helped this a lot (and actually made me think I really need to service my 38)

Can I Get It In Control?

Hand height is important to me for a couple reasons. First, I have back issues which mean I kind of need my bike setup in a certain way to minimize that. This is a personal issue and varies from rider to rider. If you’ve got enough gray hair you’ll probably understand and if you have the gray hair and don’t understand it I’m jealous for sure!

Second you gain or lose a lot of control by having hands in a position you can get power applied. This applies to both your hand height as well as width. Just like riding too wide of bars having your stack too high or low can numb the handling reducing your ability to have quick adjustments with minimal input.

I did notice that the Mega liked to be leaned in to corners more than my usual setups that I tend to understeer slightly and lean which snaps them into corners a touch faster. I’d still give the Mega passing grades on this because my hands were low combined with the fork setup not having the precise feel I’m used to after all the years of Pro Tune forks and a specific setup.

Acceleration

Some would say climbing. I don’t climb well enough to speak to it! So, for me to feel a bike’s efficiency I’m looking at how it handles burst acceleration. Heavier tires are going to change that around which I noticed on the road climb to the Luge but not as much once we got in the super tacky and then super slippery dirt…

Geo Differences

My personal bike is a Mondraker Foxy RR with a 170mm fork. So all and all most of the geo between what “I’m used to” and what I was testing was relatively close (especially when you factor the published Mondraker numbers are from a 160mm fork so mine has a slightly slacker headtube, higher bb and longer wheelbase).

The exception that I saw was on wheelbase. My Mondraker is setup with the shorter chainstay and shorter wheelbase. The published wheelbase is 1253mm – given the longer fork I’ve added a couple mm to that but I’ve never really bothered to calculate it out.

On the Mega XL the wheelbase is 1275mm which would give it a touch more planted feel and change a little bit of the direction change personality.

On the road when I put a twitch through the front end I could feel the front end was a bit more planted than my bike. I couldn’t decide if that was the MaxxGrip tire or the longer front center.

During the descent I could feel that the Mega XL was “longer” in the first few corners but that quickly went away once I had four or five turns down.

Finally – let’s take a quick look at the conditions we rode in.

Between some morning rain and being in the cloud the conditions were pretty variable. We got in some sections that were hero dirt levels of excellence – no brakes just ride in, lean as much as you want and rip through it.

Then, well, it got sloppy…

Nukeproof Mega 290 Factory Review by bikeco

Being SoCal locals none of the three of us really ride in sloppy stuff. So the details of the ride have to go back to the conditions were we have experience and kind of look the other way in conditions that are outside of the norm for us.

For instance some riders are always looking to fall in love with a demo or review bike. That’s not always going to happen (even for a bike you’ll love) and breaking down the experience can be important.

Here’s a good example of this for me:
First Ride Demo on the Mondraker FOXY
(didn’t love it but saw potential)
Extended “First” Ride when I bought one
(starting to love it – testing some stuff out, riding is ‘work’ you know!)
Extended Ride Review
(loved it by then)

Sorry for the sidebar, but the point is that you’re not always going to “love” a bike at this level at first sight. They’re technical pieces and you should treat it like that and go through what you’re really looking for out of the bike to make sure you get a bike that will get there with you. BikeCo’s staff is unbeatable at this…

Like overall – it was fun to get out with Mike and Tracy on the Nukeproof, but by the end of the ride I was kind of “blah” about having messy muddy everything to clean up, I was cold and I had a fall that dampened my spirits (and for a split second or two really scared me).

OK, not to dwell on crashes but this one was pretty funny and not that bad. If you’re familiar with the Luge picture the deep pocket turns before the trail “turns left” down the canyon with the right hand exposure. I think it’s three or five like left, right, left, right, left. Anyhow, I went in too hot as the flatter section of trail wasn’t too slippery, but as soon as it rolled into the steeper stuff it got sloppy. First corner I lost the bike, back end comes around and I’m sliding down, still up on the bike, but both wheels full drift. Into the next corner where the front end climbed up the rise and now the back wheel is in the trough, front wheel almost in the bushes still up. Still sliding. About then I see there’s really only one more turn before that left, which if I miss I’m going off the side, so my heart kinda thumps. Still at a full slide 90 degrees from the ideal direction I decide to smack my leg into the side of the trail to try to slow down and get off the back of the bike. Never fully fell just kinds slide all over and bury my leg in mud. Anyhow – I get down trail to take some more pics of Mike and Tracy and Mike’s like “ya, did you see those tracks through the corner? What a mess” or something along those lines. Then looks at me and puts together that those were all my “tracks” across the nearly the entire trail width…

When demo-ing or reviewing a bike you have to kind of put that aside to have a critical look at the bike, the setup and the spec to decide what you’re really feeling or not. I suggest that riders try to find 3 things they like, 3 things they didn’t really like and 3 things they’re neutral about to help your sales team understand if you’re on the right type / model of bike, size, spec and how the setup was.

Overall I can confidently say the Nukeproof Ride Review of the Mega 290: it’s a bike that rides planted, comfortable at speed, well behaved and consistent without knife edge performance. My experience says that for me, I would prefer ramping the suspension up to add some more “pop” to the bike to give it a little more when pumping the trail through terrain or in corners. The Mega rode “bigger” than either of my last two bikes the Mondraker or a Yeti SB130 Lunch Ride – but it should as it is a longer travel frame than either of those options.

I think it compares best to the Ibis Ripmo, maybe even a Ripmo with a 170mm fork.

Overall a fun Enduro bike comfortable and confident in terrain and speeds you’d expect!

Built at BikeCo. It Means A Lot

We take exceptional pride in providing a level of service our competition can’t match.

Few things epitomize this like our bike builds and deliveries (whether in-store or shipped to customers).

When you buy from BikeCo it’s not simply a freight forwarding service. All bikes are unpacked, components checked, frame and wheel prep taken care of, built, setup and test ridden to ensure the best performance when you take delivery.

Whether you’re picking up in-store or having a bike delivered this attention to detail minimizes potential teething issues your new bike might have giving it a longer lifespan with far less issues.

Our expert mechanics go through areas that a home mechanic might not be comfortable, or might trust that a bike packer got right such as linkage torque and fitment, bottom brackets and headsets, axle interfaces, etc, etc.

Riders are provided a suspension setup sheet with details based on their size and riding style. Our team will reach out to review your settings with you several times after delivery to help you fine tune your bike as well as understand where your settings may go as your skills advance. The same team is available for any questions you might have on cockpit setup, contact points such as grips or pedals, tire spec or setup, etc, etc. Unmatched after sales service is one of the cornerstones of BikeCo.com and a reason that so much of our business is referral or repeat clients.

Clients who take delivery of shipped bikes can expect minimal work to get a bike together and ready to ride. (we provide links with videos as well as access to our team for clients with any questions during their build up)

Assembling a typical build from a BikeCo shipment looks like:

Hang the fork and adjust the headset.
Mount the front brake.
Hang the derailleur (shifting is pre-adjusted at our shop).
Inflate the tires (they will be setup tubeless with sealant already installed – not tubes like some box bikes).
Hang the wheels.

Test ride to make the minute adjustments to your saddle and cockpit, bed the brakes in to your liking and then go get it dirty!

Bikes at this level should allow riders to get just what they want. And at BikeCo.com you can.

Upgrade or Swap Parts from Factory Build Kits

As a retailer at this level we’re able to provide our clients swaps and upgrades across builds to ensure the perfect build, performance or look!

What are the most common upgrades we see?

Brakes: a lot of personality of your bike is found in the brakes. Getting brakes that compliment your riding style will give you confidence you can slow where you need to and get off them where you want to!

btw: want to know a quick way to improve your bikes’ small bump compliance in corners and terrain? Get brakes you’re comfortable with so you can brake in the braking zone, get off the brakes and allow the suspension to reset to neutral (rather than being compressed from braking too late into the corner or terrain which produces a harsher ride than needed)

Cockpit: have a favorite bar feel? Want to upgrade to carbon bars to improve the feel? Like a specific grip? No problem we’ve got you covered across the board.

Custom Wheels: another tremendous piece of your bikes total personality. Dial in your power transfer, tracking and even trail compliance with the right rim, spoke and hub combination. Chat with our team about why handbuilt custom wheels from BikeCo.com are so popular.

Tires: Get what you want off the bat! Why start with tires you don’t like on your new dream rig?

Wireless Shifting: SRAM GX and X0 AXS upgrades are extremely popular at time of purchase.

BikeCo Pro Tune Suspension: Every Click Counts

Pro Tune custom suspension is available on FOX Factory, Performance Elite and Performance forks as well as rear shocks.

While we put “pro” in the name the reality is these custom tunes benefit everyone from a new rider to the fastest racers.

A quick synopsis: FOX suspension IS the benchmark – but, it has to be ready for riders of nearly any size and skillset. From the lightest riders tip toeing through the terrain to heavy riders smashing everything they see – and back and forth in any configuration means their tuning range HAS to be pretty wide.

With BikeCo Pro Tunes we work with you to define your riding style, terrain, ground speed, size, disposition and goals to narrow the performance window through a variety of modifications as well as proprietary oil additive packs, etc.

This narrows the FOX performance window onto of your riding specifics. Each adjustment is made more specific to you to increase your tuning capacity: Every Click Counts.

Wondering about what aspects that Pro Tuned suspension will benefit your riding? Call, email or chat with our team who can help you understand how balancing less stiction, improved compression windows, better oiling provides a better on-trail feel with less service required.

Custom Nukeproof Giga 290 Build with SRAM X0 Transmission

Custom Nukeproof Giga SRAM X0 Transmission Build by BikeCo

Enjoy some detail shots of a banging custom Nukeproof Giga 290 Build featuring the new SRAM X0 Transmission drivetrain.

The new SRAM Transmission drivetrain is the strongest and longest lasting design on the market.

When we were spec’ing this Nukeproof Giga Custom with the client an important aspect to the build was minimizing service replacements down the line: so the t-type Transmission wireless drivetrain was a must have.

Hope’s latest Tech 4 brakes build on their famous power modulation by bringing up the total power on par with other class leading MTB brakes.

The Hope V4 calipers are designed for the most aggressive riding with 4 large pistons per caliper and slightly larger pad surface compared to the Hope E4 calipers.

Looking backwards we see the Nukeproof Giga’s low slung shock mount and linkage.

Further back are Hope 2 piece rotors mounted to Hope Pro 5 hubs

Cockpit spec includes the OneUp 35mm Carbon Handlebars, Deity Grips and 5Dev Titanium Stem.

The OneUp Carbon Handlebars are popular designed to provide a touch of compliance allowing you to stay fresher longer into your descents.

Other highlights on this build include Chris King headset and bottom bracket, MRP AMg V2 Carbon Chainguide, SQ Labs 612R Carbon Rail Saddle, 213mm BikeYoke Revive V2 dropper with Wolf Tooth Remote Pro and Assegai 2.5 3C MaxxGrip EXO + front tire with a DHR 3C MaxxGrip EXO+ rear tire.

Looking for a custom bike build? You’re in the right place. BikeCo.com has specialized in custom builds from class leading Trail and Enduro brands like Ibis, Mondraker, Nukeproof and Yeti for years.

Will SRAM Transmission Fit on My Bike?

We’ve got a lot of questions on what bikes are compatible with the new T-Series SRAM Transmission Drivetrains.

So, Will SRAM Transmission Fit on My Bike?

It’s pretty easy to tell:

Does your bike have a UDH rear derailleur hanger and is it designed with a 55mm chainline?
(at this junction I havne’t seen a UDH bike, not 55mm – so basically – is your bike UDH?)

Here’s a quick look at the details that allow the SRAM Transmission to really stand out as the next generation in drivetrains, particularly with it’s automated setup.

SRAM UDH

Will SRAM Transmission Fit on my bike?

So when you heard SRAM was making derailleur hangers what was your thought?

Until I heard chatter about the Transmission system I was kind of like, great, another standard eh?

But as the advancements of the new SRAM Transmission and T-Series components came out it made a lot more sense.

Above on the Left is the hub mating surface of the new Derailleur and on the right is the surface of the UDH.

This is really the piece that allows the SRAM Transmission to take its performance to the next level: Bikes designed with the UDH provide SRAM a dedicated measurement and contact point with the hub, and therefor with the cassette.

SRAM Transmission UDH connects Derailleur directly with hub and cassette in contact

In this illustration you see how the SRAM Transmission Derailleur directly contacts the hub while also accepting the bike’s axle.

This is the importance of bikes being designed around the SRAM UDH in order for Transmission to function.

The 55mm Chainline

The latest in the ever evolving standards of MTB right? I know, part of me wants to make fun of it but the majority of me has a lot of appreciation that this sport values your dollars and continues to innovate – even if it means seemingly continual change! (I swear the next remade 1980s or early 90’s movie or TV commercial I see is gonna make me puke – at least in MTB its always doing something new…)

The wider chainline allows the Transmission system to work, provides a slightly stiffer and more robust rear triangle and requires specific cranks.

You can see the axle difference below between the SRAM GX DUB 52mm and 55mm DUB Wide cranks.

SRAM 55mm chainline versus 52mm chainline GX Cranks

So – what if your bike doesn’t have a UDH? Well non-UDH boost bikes can run the previous SRAM AXS technology available in GX, X01 and XX1 configurations.

In fact, the SRAM AXS system will still mount on a UDH bike as well if you want very specific cranks, chains, etc outside of the T-Series range.

Quick Differences between Transmission and AXS

Transmission provides automated setup and tuning as well as notable improvements to component strength and longevity.

SRAM AXS has an automatic trim tool but does require a bit of setup prior.

If you’re building a new bike most riders shopping wireless shifting will gravitate the new Transmission series as it is more robust and has some interesting design upgrades such as replaceable bash plates as well as other considerations to minimize potential damage in an extreme scenario.

If you’re updating or upgrading your current bike it tends to depend on budget (you’ll need new cranks with specific chain rings with the Transmission system), how important auto-setup is and whether your bike is UDH or not.

Whether you choose Transmission or the previous AXS you’re getting the best in wireless shifting available in MTB or eMTB.

BikeCo’s expert team assemble, setup, test ride each bike before it leaves the shop.

We go through the pivots. Ensure the suspension is functioning and setup in a rider range for the client. Make sure the shifting is crisp. Check wheel tensions, torques. The list can go on but the take-away is this: your bike is setup, test ridden, a tune sheet produced as a starting point for you – and since we’ve been doing it since 1999 this is all at a level that our competition simply can’t match.

With thorough build and test setup techniques we’re able to minimize any issues that can be common at lesser dealers on a new bike. Our goal is to have your bike ready to go when you take delivery – and, in the unlikely scenario there is an issue we’re here to take care of it quickly. We’re available 6 days a week by phone, email or webchat and will help you through a solution or get the needed bits for you fast.

Looking to learn how the Nukeproof Suspension compares to BikeCo’s other offerings of Ibis, Mondraker and Yet?

Check out the Suspension Personality tab!

Suspension Personality: Ibis, Mondraker, Nukeproof & Yeti

We get a lot of questions on why we choose the brands that we do as well as how the overall brand personalities stack up. Let’s look at how the Ibis, Mondraker, Nukeproof and Yeti bikes tend to behave and what type of riders will find a preference in their designs.

Let’s quickly examine some of the aspects that make certain MTB and eMTB designs special.

Modern MTB geo has found a more or less common ground across different types of bikes based on their designed terrain making actual suspension performance the characteristic to separate real gems from the “almost there” rigs.

Every bike’s linkage design plays a huge role in a variety of important factors for next level performance.

The class leading designs from Ibis, Mondraker, Nukeproof and Yeti feature factors that allow their bikes to stand apart. How each gets there is a little different – but these bikes are above the average in the following:

Trail Personality ABCs. Does it ride? Accurate. Behaved. Confident.

Bikes that are going to be fun for the widest range of riders are going to take all of the above into consideration.

We look for bikes that have a good balance of nimbleness and speed capacity while staying where you put them so to speak.

Are the bikes capable of climbing in typical terrain you’d expect for a riding style?

Do the bikes feel lively at consumer speeds? Are they confident transitioning into advanced or even pro race speed ranges, ie handling doesn’t become nervous?

Not all bike brands master this – for instance, prior to the Switch Infinity bikes (sometime in around say 2018?) Yeti bikes were really just absolute race machines. Everyone at Yeti was fast and every bike they built had that mentality. Some of the older Yeti’s were tough bikes for newer riders who didn’t have that aggressive capacity.

However, with the launch of Switch Infinity Yeti’s design team really addressed and produced bikes that are fun for a much wider range or rider skillsets. (Ibis was always very good at this aspect of bike design BTW)

How does each bike address the model’s “speed limit”? Obviously we’re not talking about an actual number on a limit – but some bikes have “soft” and others “hard” speed capacities. A bike with a “soft” speed limit will give a rider plenty of input that hey, we’re getting up to where your riding confidence level might have you start to whoa it back a bit. Bikes with a “hard” speed limit tend to feel amazing, until the moment they absolutely do not feel amazing and tend to spit riders out.

Whether you’re a weekend warrior, an ardent rider or a pro racer the “soft” speed limit makes for a more confident riding experience – which is one of the most important factors of design.

Rider Input: Active, Neutral or Passive?

How active are you on the bike? Do you like riding with a lot of body English? Attacking every corner and bit of terrain? That’s an Active riding style level of input.

Maybe you’re learning or progressing in a certain type of terrain and are looking for a bit more help from the bike? Maybe you physically struggle to ride actively due to back, neck, whatever type of physical ailment? A neutral riding style doesn’t mean you never move around – but maybe you’re more confident riding “in” the bike and want a bike that compliments this? Or even helps out with the occasional out of position scenario? Neutral.

So that leaves PASSIVE. How to describe that? Well, ever been on a big like notably too big for the terrain? No matter what you do the bike is simply going to do its’ own thing? Well, some brands miss on their designs and even an appropriate travel level bike can have a PASSIVE performance in the right type of terrain. Think of trying to do cornering drills on a bicycle built for two. You can want and lean all you want, but it’s gonna do it’s thing…

(We’ll touch more on how each of our brands: Ibis, Mondraker, Nukeproof and Yeti stack up to rider input below)

Tuning Range

Do the mechanics of the design lend themselves to the tuning capacity of the terrain or riding style appropriate dampers and springs (whether air specific, coil specific or setup for either).

Designers work to balance the mechanical advantage or disadvantage from the wheel, through the linkage all the way to the spring’s resistance. On multi pivot bikes that means a compromise of how your overall leverage ratios are balanced in order to produce a big that’s comfortable in the appropriate size of terrain and ground speeds.

(At BikeCo.com we do a lot of Pro Tune suspension work on brands that we don’t stock. Often it involves addressing performance deficiencies due to leverage ratios or leverage ratios outside of very specific weight and ground speed interface. But that’s a different story for a different day)

Ibis Suspension

Ibis’ DW suspension is extremely popular for new riders and experts alike.

Ibis bikes are very predictable and confident. The DW Suspension tends to be comfortable in bigger terrain than the amount of travel might suggest.

Ibis bikes are forgiving to rider position and disposition. An active rider will get even more performance out of the design – but a neutral rider, even an out of position rider on an Ibis benefits from the DW’s confident trail personality.

Ibis riders can rider “in” the bike with a nice balance between feet and hand weight input. Riding “off the back” in steeps is comfortable on the Ibis design and won’t compromise too much in terms of quick direction changes if riders shift a touch of weight onto the front for that split second of bite.

They hold lines well, they’ll go where riders tell them to, and if you find yourself suddenly above your skillset it’s a bike that’s going to have a lot in the tank to get you out of trouble.

Overall the Ibis designs have a good balance for average to heavier than average tuning. Lighter riders will note that many of the smaller frame sizes feature shocks with a lighter tune from the factory to help accommodate them.

BikeCo Pro Tune suspension is popular on the Ibis, as well as the other brands we carry, as it takes the unbeatable FOX damper range and narrows the performance window for a specific rider size, style, skillset and ground speed.

Ibis have a very soft speed limit and their performance is logical from just cruising down trail to really aggressively trying to find every bit of speed that trail will allow.

Mondraker Zero Suspension

A uniquely balanced design providing excellent confidence at speed for bikes notably nimble climbing or earlier in the speed range. An amazing balance of performance – seldom achieved at this level.

Mondraker’s suspension lends itself to active riders. Now that doesn’t mean you have to be flinging yourself all over the bike – and it is well behaved in a neutral riding position. But, if you ride mindful of terrain pumping the trail and turns, driving that front wheel into the direction change for a split second this bike will reward you with free acceleration.

A comfortable bike to ride “through your feet” (my preferred riding style at this point) the Mondraker’s are balanced, playful and fun in a wide range of terrain per model.

The Mondraker is a very precise bike capable of quick direction changes as well as holding a line through its speed range.

Overall the suspension design remains fairly neutral for all size riders. That said, my personal FOXY was spec’d with Ohlins suspension that I was too heavy to get into a compression range (so I went to a FOX 38 and Float X2 and never looked back).

Pro Tune suspension on the Mondraker is very similar to Ibis, Nukeproof and Yeti: the main goal tends to be to improve the personal adjustment range by narrowing the FOX suspension setup range for a specific rider. Every Click Counts!

The Mondraker parallels Yeti’s disposition: with a confident feel continues to invite more and more speed without becoming nervous. The bikes will communicate to a rider as they’re closing in on traction loss – I haven’t had a situation where my Mondraker simply spit me out so to speak. (And you should hear the tires groan in some corners! Just like my SB130 for all those years…)

A last note, much like the Yeti, Mondrakers are comfortable bikes at the extremes: two wheel drifts, snapping into a corner – these are bikes that if you’re capable of pushing them this hard they behave well all the way to the limits.

Nukeproof Suspension

Nukeproof’s suspension has a confident and competent on trail feel. Like the Ibis suspension Nukeproof bikes perform well for active and neutral riding styles.

Again, like Ibis, Nukeproof bikes are confident helping riders through terrain providing some leeway when you occasionally get over your head with the bike capable of bringing you back.

Active riding styles will find even more performance and speed – but the Nukeproof lineup is comfortable in direction change and holding lines without needing exceptional levels of rider input. The bikes follow directions well holding good traction at a variety of speeds with the capacity to hold a line.

Nukeproof bikes can be ridden confidently both in the bike as well as through your feet. Depending on your specific riding position your fork setup will differ, and to a lesser extent your rear shock’s compression settings as well.

Our custom Pro Tune packages for Nukeproof for the average to moderately heavier rider is pretty linear with lighter and notably heavier (myself included here) having some added variables.

Another parallel with Ibis, during custom tuning some Nukeproof riders find that Pro Tunes with increased compression tuning provide some additional “pop” to the bikes which produces a livelier feel that benefits active riders pumping the trail.

Nukeproof bikes are very confident and stable providing a very soft speed limit as you approach your speed capacity limits. Few scenarios create a nervous reaction from these bikes when ridden in their designed terrain capacities.

Yeti Switch Infinity Suspension

Designed with Yeti’s commitment to speed but without creating a numb bike at low to medium speed ranges, the modern Yeti is a poppy that offers a lot of free energy to active riders pumping the trails.

I have years of experience on the Switch Infinity with my previous personal bike a Lunch Ride SB130. This is a bike that is confident at speed all the way past its traction capacity without becoming edgy or nervous. Few bikes drift, and come back from a drift, like a Yeti will!

A combination of geo and suspension design allow the Switch Infinity bikes to be ridden both in the cockpit as well as through your feet – occasionally leaning up on the fork for super quick direction changes or to pump the trail for free speed.

Custom tuning for the Switch Infinity is variable depending on rider size and ground speed. A common Pro Tune consideration for average to heavy riders is to shift the compression settings to allow more support in the mid to mid-late shock stroke for better cornering (it allows the bike to stay taller in the travel forcing the energy through the corner instead of into the damper).

While I never found the Yeti a bike that was uneasy or nervous to ride I do feel that when I would start to get over my head I was best suited to emphasis an active riding style taking some control back from the bike rather than sitting in and letting it monster truck through things like an Ibis or Nukeproof might.

Some customers will have Yeti suspension tuned to increase the plushness and monster truck capacity as well as over-forking the bikes (Yeti tests its bikes to 20mm over fork travel spec per model) to increase the bike’s capacity for a rider who might get over their head occasionally…

Like the Mondraker Zero the Yeti Switch Infinity suspension allows active riders to push past where they likely thought their limits would be. An active riding style with a bit of a stiff front end (to keep you floating over and not burying in – whether through compression or compression and air) and these bikes are magic.

The Switch Infinity bike was the first in a LONG time that I could hear my tires working all the way to their edge of capacity before I felt like the bike had found anywhere near it’s capacity.

Mega 290 Suspension Details

Nukeproof Mega 290 Linkage

The Mega 290 features multi-link suspension. Spring support is transferred through a rocker (or bell crank, or pivot – whatever you like) link to the seatstays which applies the support against the input from the rear wheel.

This creates several angles of interest which mechanically control what percentage of the spring rate is transferred to the wheel.

At each pivot point the spring support is transferred along the linkage the angle of that input dictates the percentage of the spring rate that is resisting the input. Quick example: a spring with a 300 lb output  at a 90 degree applied angle will apply 300 lbs. As the angle changes the percentage changes based on the sin of the new angle. Sin of 90 = 1, sin of 80 (10 degrees more acute) = .9848, sin of 100 (10 degrees more obtuse) is also .9848.

The leverage ratio of these pivots also factors in – but for this let’s look at the Mega 290’s concept and not completely reverse engineer the design.

At full extension the Mega’s rear suspension sits with the shock to crank link near 92 degrees ( close to 1 to 1 spring rate applied) and the seatstay link to bell crank linkage is slightly obtuse around 106 degrees.

As the suspension sits into sag (illustrated at 30%) the shock to bell crank link becomes increasingly obtuse while the seatstay linkage angle becomes slightly acute.
Spring to linkage 105, linkage to seatstay 88.

Shown at full compression the shock to link is notably obtuse – approximately 145 degrees and the seatstay to link more acute – about 48 degrees.

In this section of linkage it produces a falling rate, or regressive mechanical advantage.

To take it a step further you can see how two other angles of interest are used to tune suspension feel and performance on the Mega 290: the Seatstay to Chainstay pivot angle and the Chainstay to ‘vertical’ from Ground Angle. (it could be argued that these combined angles are 1 functional angle to the wheel input – you can think of it either way in this case in my opinion)

This combined angle at extension measures about 120 degrees, 113 at sag and 105 when compressed.

Since these angles are closing towards 90 a rising mechanical advantage is occurring as the suspension is compressed.

Nukeproof Mega Suspension Linkage Comparison Lever Angles

In the image above you see the factors classically graphed.

The blue line represents the spring to link and link to seatstay combined angles which provide a slight rising rate from extension to sag and then a gradual falling rate to compression.

In green is graphed the lower combined (or singular depending on your thought) angle from the wheel vertical into the seatstay. This mechanically rises from extension through compression.

Below is a reinterpreted version of this graph that might be easier to grasp the rising / falling concept (inverted from previous)

Nukeproof Mega Suspension Linkage Comparison Lever Angles reinterpreted

Blue shows mixed Rising to Falling mechanics while the green illustrates overall rising mechanics.

Nukeproof Mega Mechanical Angle Advantage Suspension Chart

Now, looking solely at the input angles (disregarding the lever differences) if we combine all of the above angles the differences between the upper assembly and lower assembly produce a mechanical advantage that rises through approximately 70% of the stroke before slightly lower towards full compression.

Let’s invert the graph for a more intuitive view of the concept.

Nukeproof Mega Mechanical Angle Advantage Suspension Chart

Inverting the graph (so rising is up, and falling is down) when you review the arc you’ll see that from Extension to Sag (first 30% of travel)  through to about 60% of travel is rising notably quicker then the arc shifts to flatten and decline slightly.

This helps increase the Mega’s planted feel deep through the stroke.

Of course with the Float X2 riders have a lot of tuning capacity in the compression and volume tuning as well.

Let’s take a quick look at the arc difference between the more enduro Mega and the more trail oriented Reactor’s mechanical advantage rates.

Nukeproof Suspension Reactor versus Mega Mechanical Advantage Comparison 2

Let’s reinterpret the graph a bit logging 30% sag as the reference so we can better illustrate the comparative arcs plotted together.

Nukeproof Suspension Reactor versus Mega Mechanical Advantage Comparison reinterpretted 2

Both the 130mm travel Reactor and the 160mm travel Mega have falling rates of mechanical angular advantage in droop travel (from sag to completely extended). In fact the combined angles are extremely close.

Sag: Reactor ~ 304 and Mega ~306

At Extension the numbers are similar as well: Reactor ~ 315 and Mega ~318.

When compressed the variance is greater with the Reactor ~ 289 and the Mega ~298.

When we review the arcs a lot of the suspension’s personality and its interaction with the damper can be seen.

Note on the Mega with it’s longer travel, longer shock and longer pivot lengths the mechanical advantage rate is rising until approximately 70% of the stroke or so. Then it starts to dip back down.

Compare this to the smaller travel and “poppier” riding 130mm Reactor. Droop travel shows near parallel advantage and rise when charted. However as the bike sits deeper than sag the mechanical advantage illustrates two major personality differences.

First, it continues to rise for the entity of its length and second it rises at a greater rate per mm of travel.

This generates a more, I’ll say lively response from the fully compressed shock. Which, balanced with the lower travel, since you’d be using “full” travel in smaller terrain than on the larger bike makes sense.

Now to tune this Nukeproof has provided the best shocks on the market.

The larger travel Mega also features the more robust Float X2 shock with high an low speed compression as well as volume spacing. This gives riders range to tune “against” the mechanical drop near the end of the stroke for mom pop or support deeper into the travel.

On the 130mm Reactor the FOX Float X is spec’d with low speed compression as well as volume tuning options. For riders looking for the ultimate “plush” air suspension setup on the Reactor chat with our team about a BikeCo Pro Tune on the Float X. Using proprietary oil weights, unbeatable bleed techniques as well as (well – let’s say 7 secret herbs and spices right?) our team can fine tune the suspension’s performance for your size, riding style, terrain, ground speeds and setup.

I highly recommend the BikeCo Pro Tune on the X2 as well as the improved bleed and oil flow create a notably more consistent feel through travel and heat ranges.

What does this all mean?

Well this design lends itself to air shock tuning as overall the model suggests an accommodation at deep in the travel.

Air springs by nature are progressive, the Mega 290’s design produces a linkage that feels more plush through the travel while still providing mechanical support in conditions that utilize more shock stroke (high speed corners, chunk, etc).

As the air spring is compressed and increasing its PSI the linkage is tuning out some of that increase to keep the bike feeling planted and able to use the travel.

On the Mega 290 the FOX Factory X2 gives riders the widest tuning range utilizing the low and high speed rebound, low and high speed compression controls as well as volume spacing.

Depending on how linear of a feel is desired riders can add volume spacers (to increase the air spring’s ramp rate) or increase clicks on the compression to use the damper’s hydraulics to slow the shaft speed in certain scenarios.

Looking a little deeper you’ll see the instant center intersections illustrated extending from the linkage to seatstay and chainstay. Now there are A LOT of concepts around about the perfect fit for this and this isn’t a suspension thesis. What I will say is that having the instant center arcing near the bottom bracket, where the majority of your weight is loaded downhill TENDS (if the rest of the design is doing what it should!) to produce bikes that are easy to “drive” from your feet during direction changes, or planting them back down, etc.

The Nukeproof Mega is wheel behaved for an Enduro MTB level of travel. The Mega is designed with suspension linkage that rides neutral in most conditions and doesn’t suffer from knife edge setup concerns. That means with the FOX Float X2 riders have a wide range of settings available to fine tune what they are really looking for out of the Mega.

Those looking for poppy support in and out of corners can utilize the compression settings as well as volume spacers. This extra support is particularly notable in higher speeds and with larger riders.

Riders looking for a more linear feel will run less volume spacers and compression.

Since the X2 has great adjustability riders can even modify air pressure, typically in the 3-5% range at max, and adjust compression and volume to generate their desired performance.

Mega 290 Factory Build Frequent Swaps

Below are some common swaps for the Nukeproof Mega 290 Factory Complete

Common Nukeproof Mega 290 Upgrades

Mega 290 Factory Build Frequent Swaps

Common swaps:

Brakes: Magura and TRP are the most common changes here. Magura has more modulation while the Shimano come on a bit stronger. Riders who like Modulation may gravitate to the revised Hope 4 options which bring notably more power to the Hope lineup. TRP brakes are gaining traction for riders who like the Shimano feel but may want a touch more modulation from the longer brake lever.

Wheels: Onyx silent hubs, Chris King hubs, and Industry Nine are at home on a build at this level. We work with a range of carbon rims to allow you to fine tune rim width and stiffness as well. Wheels are a BIG part of a bike’s personality so chat with our team to get it right the first time!

Cockpit: If you have a cockpit you like let’s get it on the bike. Or upgrade to a carbon bar or 35mm combination to find tune your build.

Seating: Like cockpit, if you have a saddle or seatpost you love its a common change across all the builds.

SRAM Wireless Shifting: Upgrade to wireless shifting at time of purchase.

Reactor 290 Suspension Details

Nukeproof Reactor 290 Linkage

The Reactor 290 features multi-link suspension. Spring support is transferred through a rocker (or bell crank, or pivot – whatever you like) link to the seatstays which applies the support against the input from the rear wheel.

This creates several angles of interest which mechanically control what percentage of the spring rate is transferred to the wheel.

At each pivot point the spring support is transferred along the linkage the angle of that input dictates the percentage of the spring rate that is resisting the input. Quick example: a spring with a 300 lb output  at a 90 degree applied angle will apply 300 lbs. As the angle changes the percentage changes based on the sin of the new angle. Sin of 90 = 1, sin of 80 (10 degrees more acute) = .9848, sin of 100 (10 degrees more obtuse) is also .9848.

The leverage ratio of these pivots also factors in – but for this let’s look at the Reactor 290’s concept and not completely reverse engineer the design.

This suspension model was build with the flip chip setup with the pivot in the more “forward” position (which would produce the slacker headtube and taller bottom bracket configuration).

At full extension the Reactors’s rear suspension sits with the shock to crank link about 75 degrees and the seatstay link to bell crank linkage is obtuse around 116 degrees.

As the suspension sits into sag (illustrated at 30%) the shock to bell crank link becomes increasingly obtuse (angle increases) while the seatstay linkage angle becomes more acute (angle is decreasing).
Spring to linkage 87, linkage to seatstay 98.

Shown at compression the shock to link sits at approximately 117 degrees and the seatstay to link more acute – sitting about 62 degrees.

When you combine these angles you find extension at 191, sag at 185 and compressed at 179. This means as the suspension is compressing the upper linkage is generating a slightly rising mechanical advantage (the spring is applying at closer and closer to 1:1 as the sine is adjusted).

Going a step further let’s look at the lower pivot point and how it helps interpret the spring and ground force balance.

The illustrations show a combination of 90 degrees to the ground to the chainstay pivot and then the angle between the chainstay and seatstay. For ease we’re going to combine them.

At Extension its about 124 degrees, at Sag closer to 119 and Compressed around 110 degrees. Since these factors are closing towards 90 degrees (or 1:1) the mechanical advantage is also rising on the lower pivot assembly.

Nukeproof Reactor 290 Suspension Linkage Mechanical Advantage Comparison

Above you see the factors classically graphed.

The blue line represents the spring to link and link to seatstay combined angles. Note that unlike the larger travel Mega the arc continues down through its stroke. This means the the mechanical advantage is continuing to rise during compression.

The green graph shows the angular change for the lower pivot between the ground vertical and seat stay. Like the upper arc it continues a steady decline.

Below is a reinterpreted version of this graph that might be easier to grasp the rising / falling concept (inverted from previous)

Nukeproof Reactor 290 Suspension Linkage Mechanical Advantage Comparison reintrepreted

Both the arcs illustrate rising mechanics with a relatively small diameter arch compared to longer travel Nukeproof bikes we’ve mapped.

Nukeproof Reactor 290 Suspension Linkage Mechanical Combination Graph

Combining all the angles (disregarding the lever differences) it makes sense to see increasing mechanical advantage (since both linkage points are increasing).

Let’s invert the graph for a more intuitive view of the concept.

Nukeproof Reactor 290 Suspension Linkage Mechanical Combination Graph reintrepreted

Above we’ll show the combined angles reinterpreted to help with more “logical” rising and falling comparison.

The Reactor’s 130mm design’s increasing mechanical angular advantage helps produce a vibrant, poppy bike. Looking at the arc from the Sag point the suspension is designed to allow good small bump compliance while the increasing advantage helps the shock provide support deeper in the travel.

Let’s compare the Reactor and the larger travel Mega’s combined angle advantage for an example of how different travel bikes feature various accommodations for tuning.

Nukeproof Suspension Reactor versus Mega Mechanical Advantage Comparison 2

Let’s reinterpret the graph a bit logging 30% sag as the reference so we can better illustrate the comparative arcs plotted together.

Nukeproof Suspension Reactor versus Mega Mechanical Advantage Comparison reinterpretted 2

What does this all mean?

Back to the Nukeproof Reactor specifics!

The Reactor’s suspension is designed to balance a plush pedaling platform with increasing support deeper in the shock’s stroke for more “pop” (or returned energy to the bike). This means as you pump the trail the Reactor will help you actively accelerate as the suspension absorbs and reapplies is energies.

Looking a little deeper you’ll see the instant center intersections illustrated extending from the linkage to seatstay and chainstay. Now there are A LOT of concepts around about the perfect fit for this and this isn’t a suspension thesis. What I will say is that having the instant center arcing near the bottom bracket, where the majority of your weight is loaded downhill TENDS (if the rest of the design is doing what it should!) to produce bikes that are easy to “drive” from your feet during direction changes, or planting them back down, etc.

The Instant Center on the Reactor varies from near the chainstay pivot at full extension to forward and slightly lower than the center of the bottom bracket at compression.

On the Mega the instant center travels from ahead of the bottom bracket and slightly above the chainstay pivot much further forward and down comparatively.

Both bikes ride as expected for their class – so I’m going to leave that data uninterpreted at the moment – but figured readers might enjoy a little more data that our suspension team takes into account.

Overall the Reactor’s suspension is what you’d expect on an aggressive trail bike. The Float X damper gives riders more tuning capacity than the lighter DPS option would as well as a bit more heat capacity.

The design and shock spec lends itself to heavier from down-country through into enduro trails. Lighter than average riders will find the Reactor comfortable and confident in larger terrain for the class, but might consider Pro Tune or damper options if spec’ing a down-country or trail endurance type bike.

Narrow available springs by shock size and spring rate.

Wondering which spring is for you? Want to learn more? Scroll down to learn about eMTB and MTB Coil Fitment as well as how Pre-Load settings allow spring cross over and thus more or less progressive spring rates through the coil’s travel!

eMTB and MTB FOX Coil Spring Fitment

Here are some physical dimensions to take into consideration when shopping for the right eMTB or MTB Coil Spring.

FOX Coil ID: Inner Diameter

Current FOX Coils are Inner Diameter: 1.385″

The correct inner diameter ensures proper clearance to the damper body and proper upper and lower “spring perch” sizing.

Coil Stroke versus Shock Stroke

We’ve listed the published stroke or coil travel for each part number.

The Coil Stroke should be greater than, at least slightly, than the Shock Stroke (taking into account that some coil stroke is used with the Pre-Load adjustment – more on that on the next tab).

If your Coil Stroke is equal or, much worse, LESS THAN the shock stroke you will have Coil Bind.

Coil Bind

Example of Coil Bind on MTB or eMTB suspension

Example of Coil Bind on MTB or eMTB suspension shown above.

Coil Bind is when a spring is compressed completely sitting each coil against its neighbors.

Coil Bind may cause damage to the damper body, suspension, bike and rider.

When a coil is completely compressed it is no longer a spring, so the spring rate goes to infinity (like a hard tail bike). This typically results in a bounce which then unloads the spring to “pogo” making the entire situation worse. Coil Bind should be avoided by ensuring that your spec’d Coil Stroke or Coil Travel is greater than the Shock Stroke.

Coil Total Length

The coil capable FOX dampers have an adjustable ring for Pre-Load as well as to accommodate various Total Length coil springs.

Read onto the next Tab for more information about fine tuning your FOX DHX2 Coil using Pre-Load and Spring Rate to adjust your coil spring setup’s progressiveness!

Tuning with Pre-Load & Spring Rate

We’re going to use the FOX DHX2 damper as an example to show you how multiple spring rates will produce similar resistance at a SAG measurement while allowing riders to fine tune the available resistance later in the stroke, often quite notably.

We touched on Spring Rate in the Fitment tab – it’s measured in LBs/IN – how many pounds it takes to move the spring some portion of an inch. Since this is consistent it creates what’s considered a linear spring rate (it will graph in a line) compared to a progressive spring rate of an air shock (which graphs in a “J” shape).

First let’s look at Pre-Load

FOX recommends a minimum of 8 clicks of Pre-Load on a spring and allows for a maximum of 26 clicks (to minimize the chance of coil bind as well as controlling the forces on the spring perches, threads, etc)

So you install the coil, tighten the Pre-Load perch down to contact and then adjust it between 8 and 26 clicks to fine tune your SAG setting, which we’ll say is 30% of the SHOCK TRAVEL. If your coil is sized appropriately – ie more coil travel even with Pre-Load added than available shock travel the coil will be at less than 30% of it’s travel. So remember, the measurement you’re looking for is a difference that equates to 30% of the SHOCK stroke.

example: 55mm SHOCK stroke = 16.5mm of SAG at 30%. so a 210x55mm shock will have an eye to eye endearment of 210-16.5= 193.5mm. If you measure off another component adjust your math as needed (such as spring perch to spring perch, etc depending on accessibility of the shock in your frame).

If with the minimum of 8 clicks your sag setting is LESS THAN 30% sag you’d benefit from a lighter spring rate.

Should 26 clicks find you at MORE THAN 30% sag a firmer spring rate is required.

Spring Rate Cross-Over with Pre-Load Adjustments

Here’s where it gets interesting: Variations in Pre-Load settings create overlap at SAG PSI – meaning you likely have a choice if you want to use the higher spring rate at a lower Pre-Load (which will have a more aggressive spring rate deeper in the travel) or use a lower spring rate at a higher Pre-Load (which will have less aggressive spring rate deeper in the travel).

Here’s an image from our calculator as a quick reference:

BikeCo eMTB and MTB Coil Comparison Example

You can see there is cross over at sag, highlighted in light yellow, between the higher Pre-Load Settings on the 250# coil as well as the lower Pre-Load Settings on the 275# coil.

Looking at the rest of the charts you can see that the higher spring rate coil will provide higher resistance as you pass the 30% SAG measurement. This is kind of like how volume spacers are used to adjust an air spring’s ramp rate.

Want to explore the crossover more? You can use the google sheet FOX Coil Spring Rate calculator here (opens in new tab).

Quick Details on Rising / Falling Rate Suspension

How much of the spring’s power is actually applied into the linkage varies in part tied to the angle of the linkage compared to the spring’s “push”. As this angle is variable with suspension linkage the percentage of the springs actual output to the suspension system will vary.

eMTB and MTB Rising and Falling Rate Suspension Concept

Rising / Falling Rate Suspension Illustrated

Above you’ll see a basic illustration showing two rising then falling rate suspension linkages.

What makes this important – a coil spring (or air spring) is only 1 to 1 effective when the spring’s power is pushing at 90 degrees to the linkage arm. On the upper graphic this is shown in the Orange details.

Continuing to reference the upper graphic: at full extension the spring’s effectiveness will be slightly less than the spring’s power rating. As the linkage rotates (clockwise in this case) to the 90 degree angle (shown in orange) it is a Rising Rate suspension.

As the linkage passes the orange 90% point until full compression it is a Falling Rate suspension.

How does this matter or effect you?

Well if you’re read this far I hope you’re learning something and it’s interesting right?

Let’s compare the red details between the upper and lower illustrations now.

In the upper illustration the angle between the spring and linkage is more exaggerated than the lower illustration.

This means at full compression the upper spring is exerting a percentage LESS of it’s rated power compared to the lower red detail which is closer to the 90 degree position, thus it is exerting a HIGHER percentage of the spring’s rated power to the linkage.

If I was considering two spring rates I would likely consider using the HIGHER Spring Rate with less Pre-Load in the upper concept and the LOWER Spring Rate with more Pre-Load in the lower scenario.

Is this somewhat splitting hairs? Of course. But, the data is out there, the components are out there so what harm can the knowledge do? (and, I hope that a disclaimer like this eliminates the snarky comments, or at least some of them!)

Final Thoughts on the Above Calculator

So, the calculator won’t tell me what spring to use? Correct. There are too many individualized factors in each bikes’ design to make that really feasible. This calculator ideally gives you a comparison point if you’ve started with some understanding or data point on your setup.

Your bike dealer or manufacturer should be able to provide you with some basic setup concepts and the calculator would provide a reference to compare options around what they suggest.

This spring calculator is based around the actual support produced by the spring at full extension with Pre-Load, 30%, 60%, 90% and 100% of the available SHOCK STROKE.

The methodology is calculating the distance that the SPRING STROKE would be compressed in those various states of SHOCK STROKE, in inches, times the Spring Rate in LBs/IN.

Since variations in Pre-Load will create shifts in the total compression length of the SPRING STROKE that is factored into the results.

This calculator DOES NOT take into account bike specific details such as leverage ratios, rising / falling rates, etc. It is available to easily compare cross-over as well as spring specific output.

Quick Details on Rising / Falling Rate Suspension

How much of the spring’s power is actually applied into the linkage varies in part tied to the angle of the linkage compared to the spring’s “push”. As this angle is variable with suspension linkage the percentage of the springs actual output to the suspension system will vary.

eMTB and MTB Rising and Falling Rate Suspension Concept

Rising / Falling Rate Suspension Illustrated

Above you’ll see a basic illustration showing two rising then falling rate suspension linkages.

What makes this important – a coil spring (or air spring) is only 1 to 1 effective when the spring’s power is pushing at 90 degrees to the linkage arm. On the upper graphic this is shown in the Orange details.

Continuing to reference the upper graphic: at full extension the spring’s effectiveness will be slightly less than the spring’s power rating. As the linkage rotates (clockwise in this case) to the 90 degree angle (shown in orange) it is a Rising Rate suspension.

As the linkage passes the orange 90% point until full compression it is a Falling Rate suspension.

How does this matter or effect you?

Well if you’re read this far I hope you’re learning something and it’s interesting right?

Let’s compare the red details between the upper and lower illustrations now.

In the upper illustration the angle between the spring and linkage is more exaggerated than the lower illustration.

This means at full compression the upper spring is exerting a percentage LESS of it’s rated power compared to the lower red detail which is closer to the 90 degree position, thus it is exerting a HIGHER percentage of the spring’s rated power to the linkage.

If I was considering two spring rates I would likely consider using the HIGHER Spring Rate with less Pre-Load in the upper concept and the LOWER Spring Rate with more Pre-Load in the lower scenario.

Is this somewhat splitting hairs? Of course. But, the data is out there, the components are out there so what harm can the knowledge do? (and, I hope that a disclaimer like this eliminates the snarky comments, or at least some of them!)

Final Thoughts on the Above Calculator

So, the calculator won’t tell me what spring to use? Correct. There are too many individualized factors in each bikes’ design to make that really feasible. This calculator ideally gives you a comparison point if you’ve started with some understanding or data point on your setup.

Your bike dealer or manufacturer should be able to provide you with some basic setup concepts and the calculator would provide a reference to compare options around what they suggest.

eMTB and MTB FOX Coil Spring Fitment

Here are some physical dimensions to take into consideration when shopping for the right eMTB or MTB Coil Spring.

FOX Coil ID: Inner Diameter

Current FOX Coils are Inner Diameter: 1.385″

The correct inner diameter ensures proper clearance to the damper body and proper upper and lower “spring perch” sizing.

Coil Stroke versus Shock Stroke

We’ve listed the published stroke or coil travel for each part number.

The Coil Stroke should be greater than, at least slightly, than the Shock Stroke (taking into account that some coil stroke is used with the Pre-Load adjustment – more on that on the next tab).

If your Coil Stroke is equal or, much worse, LESS THAN the shock stroke you will have Coil Bind.

Coil Bind

Example of Coil Bind on MTB or eMTB suspension

Example of Coil Bind on MTB or eMTB suspension shown above.

Coil Bind is when a spring is compressed completely sitting each coil against its neighbors.

Coil Bind may cause damage to the damper body, suspension, bike and rider.

When a coil is completely compressed it is no longer a spring, so the spring rate goes to infinity (like a hard tail bike). This typically results in a bounce which then unloads the spring to “pogo” making the entire situation worse. Coil Bind should be avoided by ensuring that your spec’d Coil Stroke or Coil Travel is greater than the Shock Stroke.

Coil Total Length

The coil capable FOX dampers have an adjustable ring for Pre-Load as well as to accommodate various Total Length coil springs.
