When you buy a bike from BikeCo.com you’re not getting simply a forwarded box.

Our team goes through quality control checks, builds, tunes and provides a base setup for each bike. This allows us a better chance to find the rare mechanical warranty issue, to ensure that the linkage and bearings are properly setup.

A suspension setup guide is provided and our team will begin working with you to ensure as your riding develops with your new bike suspension settings, cockpit setup, tire pressures, etc are addressed to keep you progressing.

Since we build every bike we can also offer part swaps and upgrades our competition simply cannot!

Looking for different tires? Brakes? Cockpit or Seating? Not a problem. Our team is happy to help you. Chat with our sales team about during and after purchase incentives on riding gear and accessories as well!

Your new bike typically will arrive with an absolute minimum of work required to get you on the trails. Usually this involves installing the handlebars, adjusting the headset and mounting the front and rear wheel. It’s that easy – and if you have questions you have access to the sales team and a variety of videos from BikeCo.com to help you.

Questions? No problem. Hit us up.

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.

Compression.
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

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

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.
