BikeCo Exclusive: Pro Tune Suspension

There are a lot of reasons to shop at The Bike Company ( Some are: Unmatched attention to detail. Incredible after sales setup follow up. Pro Tune Suspension.

Our team works with the FOX fork and shock lineup to take the already great FOX suspension to the next level. Working with our team of suspension tuners we will narrow the FOX performance window based on your size, riding style, terrain, ground speeds, aggression, goals and chassis.

What’s it mean to narrow the performance window? Well, each click is more precise. The fluid is hand picked for you. The bleed is more precise.

BikeCo Pro Tune Suspension: Every Click Counts

On trail your suspension will be more plush while maintaining the support and progression you need to really attack the trail.

For racers our tuned suspension subtracts seconds from your run. For pleasure riders it improves the traction and feel allowing you to progress quicker in your riding.

Talk to our team about the advantages of BikeCo Pro Tunes today.

Looking for a better understanding of suspension to dial in your Giga 290? Check out the videos and write ups below to learn how suspension adjustments interact.

Learn about suspension setup basics on the following tabs. Each tab has a video with the basics of Air Spring / PSI, Volume Spacers, Compression, Rebound (or watch it all in one place with the final tab).

Each tab has a text section with a bit more in-depth look at the typical MTB suspension settings and how they intertwine.

PSI / Spring Rate

MTB suspension must accommodate a wide range of rider weight. To achieve this nearly all forks and rear shocks use an adjustable air spring.

By varying air pressure riders set a desired sag, or percentage of travel that the bike “sits into” under neutral loading.

Modifying this sag percentage will change small bump compliance as well as bottom out characteristics.

Learning how to Pre-Charge your suspension pump will help you make finite adjustments to sag.

Typically 15% sag is for a firm setup and 20% sag is considered plush.

Air Spring Fine Tuning Control(s): Volume Spacers & Compression

Volume Spacers
Air springs ramp rate, sometimes called Spring Rate, is based on how air compresses in the containment cylinder. As the air is compressed the PSI increases according to the decreasing volume of the containment. This is done via non-compressible volume spacers in the air chamber.

Hydraulic damping assists air spring providing support in mid-stroke and bottom out.

Opposing Control: Rebound.
Higher spring rate will drive the suspension back to neutral with more force than a lower spring rate. To keep the bike from skipping across trail rebound damping is utilized.

Volume Tuning

As suspension compresses (travel reduces) a piston moves closer to the end of a sealed container. By decreasing the volume of the container the PSI pushing back on the piston is increased.

By adding or removing non-compressible volume spacers riders modify the air spring’s ramp rate which directly changes the amount of support and bottom out feel of the fork or shock.

By removing volume spacers a rider increases the available volume in the suspension. The larger volume compresses less per mm of travel resulting in a lower PSI per mm of travel. This creates less support and is utilizes more travel.

Adding volume spacers decreases the available volume. With less air volume the PSI per mm of travel increases providing more support and greater resistance to bottom out.

Opposing Control: Rebound.
Rebound may need to be adjusted for volume tuning depending on how drastic of a PSI change is being tuned in or out of the suspension.

“Helping” Control: Compression.
Compression provides additional support and bottom out resistance.


Compression controls provide damping to slow suspension travel as a load is applied and the suspension is compressed. (easy one right?)

When riders have found sag and volume spacing preferences compression controls provide minute adjustments to dial in performance. Adding compression provides more support allowing the suspension to ride taller in its travel which is important when dialing in a bike’s personality in corners, etc.

With too little compression a bike will sit deep in the travel. This compromises cornering and braking force resistance. Headtube angle, bottom bracket height, front to rear weight bias, etc are modified as a bike goes through its travel. Maintaining control of the use of travel is paramount for good performance.

Since compression hydraulically slows the suspension’s use of travel it therefor lowers the air spring’s PSI. Properly setting compression controls will help ease the load on the rebound system by controlling the air spring’s push back onto the rebound circuit.

Too much compression will cause a bike to feel harsh and not use appropriate amounts of travel.

Generally, compression settings are fine tuned after sag and volume spacing have riders “in the ballpark.”

Low speed compression controls mid-stroke as well as support in cornering and against brake dive.

High speed compression helps with bottom out and high shaft speed inputs.

3 positions switches are a type of compression circuit with Open the most plush, Mid providing some additional support and Firm for climbing. If you climb in firm remember to put it back to plush for the downhill or you’re in for a potentially rough ride.


Rebound damping controls a suspension’s shaft speed returning to a neutral position. Or, how fast the air spring pushes back as the load changes.

More rebound damping slows the suspension by decreasing the amount of fluid allowed to pass through the hydraulic design.

Less rebound damping allows the suspension to return faster with less hydraulic restriction on the damper.

Rebound setting is based on weight, ground speed, terrain and aggression. Setting the rebound properly means finding the right frequency or feel for your riding.

If your rebound is too fast, or doesn’t have enough clicks of rebound, the bike will tend to skip and suffer poor small bump compliance.

When the rebound is too slow, or you have too many clicks of rebound, the suspension may “pack up” creating a harsh ride as each bump uses progressively more travel forcing the suspension deeper into the travel, which will have higher spring rates.

Opposing: Air Spring PSI / Spring Rate.

“Helping” Control: Low & High Speed Rebound.

Some suspension is designed with 2 rebound circuits. The High Speed Rebound circuit is designed to provide additional control resisting increased PSI late in suspension travel.

Typically High Speed Rebound settings are used as the Low Speed Rebound controls edge towards closed. Example: you might not use any clicks of High Speed Rebound until you reach “X” clicks on the low speed.

Giga 290 Comp Build Frequent Swaps

Below are some common swaps for the Nukeproof Giga 290 Comp Complete

Giga 290 Comp Build Frequent Swaps

Common swaps:

Suspension: Many riders like the Deore build starting point but prefer FOX Factory or FOX Performance Elite suspension to provide more room to grow down the line.

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.

Nukeproof Giga 290 : Comparative Bikes

If you’re shopping an all mountain capable MTB you’re in the right place.

The Giga 290 is slightly larger than the Mega 290’s 170/160mm suspension puts it in with bikes like the Yeti SB160 and Mondraker FOXY. While all of these bikes have enough suspension to be “bruisers” all three pedal surprisingly well. The Giga gives up just a touch uphill to those chassis however the larger bike downhill is popular with Super Enduro, Big Mountain and Park Riders.

The Giga 290 Factory build provides a great value as an XT complete build with FOX Factory Suspension front and rear.
