FOX 36 Forks

2025 FOX 36 Forks

Updated this year the FOX 36 is available with either the GRIP X2 or GRIP X damper. 2025 FOX Float 36 forks are offered in 27.5″ or 29″ chassis in 150 or 160mm travel. While the FOX 38 has taken over the full tilt enduro rider many aggressive trail and light enduro riders will find the FOX 36 fork fits their riding style.

Keep reading for FOX 36 Fork details. Learn about the GRIP X2 versus the GRIP X damper, the FOX 36’s air spring and volume spacers, brake and wheel specs as well as other details on the FOX Float 36 lineup.

For 2025 the FOX 36 lineup offers riders two dampers.

Replacing the GRIP2 for maximum tune-ability, with HSC, LSC, HSR and LSR riders find an upgrade with the FOX GRIP X2. FOX went no holds barred with this damper increasing the valve base diameter and more than tripling the valve stack as well as revising the overall architecture to decrease the damper’s reaction to rider and trail input. Aggressive, larger or riders with high ground speeds will gravitate to the GRIP X2 option.

For a more all-around feel, that fork that’s capable of aggressive trail and light enduro without sacrificing all its mellow trail manners – as well as having a climb switch – riders find the new GRIP X damper. This damper provides HSC, LSC and LSR. Lots of tuning range while coming in lighter than the GRIP X2 and previous GRIP2 damper. The GRIP X has notably more feel and capacity than the earlier FIT4 option while still retaining the often sought after climb switch.

Why Riders Choose BikeCo.com for Suspension

There are many reasons riders choose to purchase suspension from BikeCo.com. Two of the most notable are our proprietary BikeCo Pro Tune services available on FOX products as well as our unbeatable after-sales service and setup availability.

FOX forks and shocks have distinguished themselves as class leaders across all MTB disciplines. With a wide range of dampers, adjustments, travel options as well as chassis riders have options to dial in their bike. But, working with BikeCo.com you’ll get more out of your new fork or shock and it’s something the competition simply can’t offer: Access to our team’s combined expertise on setup and tuning.

Modern suspension offers a range of adjustments. PSI, Volume Spacing, Compression – possibly High and Low Speed as well as Rebound – again possibly high and low speed.

While many manufacturers offer basic setup points the magic is being able to fine tune the fork or shock to accommodate your riding specifics. Working with the team at BikeCo.com riders are able to more quickly dial in a setup as well as understand where their setup is likely to advance as riding speeds and confidence increase.

Clients purchasing Suspension products from BikeCo.com will take delivery with a personalized setup sheet with suggestions for a starting point (as well as somewhere to come back to if you decide to spin all the knobs during your setup pedal in front of the house!).

Our team will then reach out at intervals with questions to help us understand how the fork or shock works for your individual riding. These intervals are designed to allow you a couple rides to quantify your impressions and then readdress minor changes to the setup. Of course, our team is available at any point in between if you have questions on your suspension.

Since 1999 BikeCo’s suspension experts have worked with a wide range of riders. From World Cup Level Pros to brand new riders. With this experience we are unmatched at setting up bikes performance, so the rider isn’t fighting the tune but simply concentrating on riding the trail.

Our team works together with our suspension tuners and BikeCo owner Joe Binatena to ensure clients get the best setup and tune concepts in the industry.

We will help you define how one adjustment may effect another setting as well as help you understand how your suspension is interacting with other components. Don’t get lost spinning dials when you can work with the best and have a thorough understanding, or simply someone to tell you which dials to turn if you’re that rider!

PSI, Ramp Rate, High and Low Speed Compression, High and Low Speed Rebound, Cockpit Setup, Brake Setup, Tire Pressures and Sidewalls, Riding Positions, Terrain – a lot of things going into really dialing in how your bike feels through the chunk, into corners and under power.

With experts working in your corner why would you shop MTB or eMTB Suspension anywhere but BikeCo.com?

Want to take your FOX Suspension to the next level? Why not have a personalized tune to provide a better setup range based on your specifics?

BikeCo Pro Tune Suspension

  • FOX Pro Tunes by BikeCo.com

    Take your riding to the next level with a proprietary suspension tune from BikeCo.com on your FOX fork or rear shock.

  • FOX Suspension is an acknowledged class leader across all MTB and eMTB disciplines. But, FOX is building suspension for the masses and BikeCo is Pro Tuning that suspension for you!

    What's that mean? FOX suspension is designed with a functional range for nearly any size rider with any skill set. This means even with many clicks of adjustment you might find it a little tough to find the perfect sweet spot. When you have suspension that has to accommodate riders that may be twice the size of each other and with huge variations of confidence, riding style and speed that's not a knock on FOX, it's just a reality.

    BikeCo Pro Tune Suspension takes the unbeatable FOX performance and narrows the performance window based on your specifics. Size, riding style, terrain, aspirations, aggresion and ground speed as well as what bike you're riding all go into our BikeCo Pro Tune design considerations.

    Our Pro Tune services include a range of proprietary lube and damper oil selections additive packages for performance across a wide range of altitude and temperatures based on your weight and riding style. Custom internal tuning considerations are used also based on the end user (none of which compromise your warranty). Improved damper bleeds, upper and lower fitment considerations, etc - all gained from years of working with the faster racers at the highest level and adapting them for every level of rider.

    In fact, while named Pro Tune it's often newer riders who benefit most from having tuned suspension (and having access to the BikeCo team to help them fine tune the setup). Why try to learn to ride AND fight a poor setup? Poor setup hinders rider advancement, confidence and fun. Don't tolerate that!

    BikeCo Pro Tune services are available on new or used FOX forks and shocks. If you're purchasing new suspension we offer a price incentive at time of purchase for up to 6 months after your purchase!

FOX GRIPX2 Damper Details

New for 2025 FOX’s longer travel and more aggressive forks have been fit with the new GRIP X2 damper.

The GRIP X2 replaces the previous GRIP2 damper on the top tier Factory Kashima FOX 38 forks. The GRIP X2 damper is designed with mechanical differences giving it an on trail performance advantage to the previous GRIP2 dampers.

What are some of the notable updates?

Bigger is Better. Well, with Base Valves!

On the GRIP2 damper the base valve measured 20mm. With the revised GRIP X2 FOX increased the base valve to 24mm.

FOX also took the GRIP2’s 7 valve stack and increased it on the GRIP X2 to a 23 count valve stack. This improves the overall tune capacity with the goal of improving the fluid engagement through the damper.

Confidence with Compression: Adjusting your fork

7 15 19 Compression and Confidence

Confidence with Compression: Adjusting your fork

Confidence with Compression – sort of a vague title right? Am I gaining confidence on trail from compression? Am I confident adjusting my compression? Well, both.

The abridged back story: I had a chance to move further south. BikeCo’s website has been growing at a rate that I can now work remotely mostly and come up to the shop a couple times a week. Anyhow – for the first time since I started bikes I’m consistently riding trails I don’t know. This presents some really fun challenges particularly as I tend to ride solo most the time.

Now I didn’t move and decide I was one of our pro riders looking for the most ridiculous lines possible. Nor did I move and decide I was going to find every gravel trail to take my SB130 on. I’m riding the same basic level of trails but the unknown adds quite a bit to riding. Continue reading Confidence with Compression: Adjusting your fork

44mm vs 51mm Fork Offset

44mm vs 51mm Fork Offset

Many clients use our custom builders to quickly spec the parts they need for frame swap projects. That’s awesome. We’re glad to dial in everything from frame swaps, factory builds, semi to full custom bikes with our clients. We have had A LOT of clients ask about utilizing previous generation offset forks to their new bikes. Let’s take a look at the advantages of the lower offset forks, particularly the 29″ 44mm versus 51mm offset.

I guess let’s start at the end.

29″ bikes have reached an amazing level of performance. Modern 29’s pedal amazing while being much more behaved on the descends. We see smaller riders enjoying the current generation of big wheel offerings. Compare this with the days when Small 29’s weren’t even made because they scare riders out of the sport!

Front End Support – Fork Air, Volume & Compression

Front End Support – Fork Air, Volume & Compression

Between our BikeCo Pro Tune services as well as working with some of the fastest racers in MTB we get a lot of questions regarding suspension tuning. Modern forks offer more ways than ever to dial in your ride. Getting the right front end support with fork air, volume and compression improves tracking, ride quality, dive, and how your bike performs in the chunk.

Recently BikeCo Pro Rider Cody Kelley was in town working with Joe Binatena on the 2019 Alchemy Arktos 29. It was an interesting opportunity to sit down and listen to Cody and Joe discuss setup. Continue reading Front End Support – Fork Air, Volume & Compression

Trust Message Fork Review, Geometry

Trust Message Review Trail

Trust Message Fork Review, Geometry

At BikeCo.com we receive a lot of questions on suspension and bike setup. What works for who, how and why. With the launch of the carbon fiber Trust Message fork we’ve had many clients reach out. This blog is a Trust Message Fork Review concentrating on geometry and application.

As stated by Trust the Message fork rides unlike telescopic options. The Message utilizes an arced axle path from a pair of pivot arms with a leveraged air spring and damper. The differences in ride are somewhat hard to lay out after only a couple rides on the chassis. So rather than add to the “what I feel” category let’s look at factors in the wheel arc as well as the fork’s overall geometry. Continue reading Trust Message Fork Review, Geometry

150 vs. 160 Fork Headtube, Trail & Flop

150 vs 160 fork headtube trail flop comparison

150 vs. 160 Fork Headtube, Trail & Flop

The Story Behind the Images. Looking at 150 vs. 160 Fork Headtube, Trail & Flop

I wrapped up the 150 vs 160 comparison and needed an image. I grabbed BikeCo’s demo SB130 (with a stock setup) and mine with the 160 fork and headed out. And struggled. I couldn’t get an image to show with any level of credibility the difference in crown race height. With a 10mm steer spacer in hand I tried to figure out how to photograph such a small difference.

Some quick math said the axle to crown height difference when the forks were standing straight up would be only 1.76%. Less when you factor in the headtube angle when viewed straight on.

Intrigued I downloaded a trial of AutoCad recalling my old design days. Continue reading 150 vs. 160 Fork Headtube, Trail & Flop

Fork Volume Spacing Calculator with Sag

9 4 18 Volume Sag Calculator BikeCo

Fork Volume Spacing Calculator with Sag

We had a lot of click through, emails, chats, etc on the previous volume spacing calculator. We decided to produce second to help riders better understand tuning windows. Check out BikeCo’s Fork Volume Spacing Calculator with Sag.

Like the previous calculator this works best on a computer. It will work on a mobile device however the data will stack vertically. It is again based on the basic dimensions of a 160mm Fox 36 Float Grip 2 fork.

Expanding on the concepts in the earlier calculator this offers riders a chance to look at how adding or subtracting sag in correlation with volume spacing changes PSI. Use the calculator to gain a visual concept on how modifying volume spacing, sag or both will change a PSI ramp rate. Continue reading Fork Volume Spacing Calculator with Sag
