COLLOSUS N9
Features
-
IFS Suspension
An innovative 6-bar suspension system developed between the race tape. IFS decouples braking and pedalling forces, whilst retaining complete control over leverage ratio and axle path. The result is class leading small‑bump sensitivity and traction, controlled anti‑rise under braking, and consistent leverage progression for high‑speed stability and impact control.
-
29/ MX Compatible
Switchable between 29” and MX setups with easy-to-use seatstay flip chips. No extra parts needed to secure a mullet setup.
-
PolyPocket frame storage
Frame storage always helps save the day - the PolyPocket keeps your trailside spares secure and within reach. The insert bag attaches with a Velcro backing for a rattle-free fit, and includes a stopper to prevent sliding toward the bottom bracket.

FAQ
-
The bike comes with 29x2.6” tires front and rear. Can I fit 27.5” wheels to convert it to a ‘mullet’ set up?
The frame has clearance for a 27.5x2.8" tire so a mullet (29” front, 27.5+ rear) is possible. However, the diameter of a 27.5x2.8" tire is significantly smaller than the standard 29x2.6" tire, hence changing to a mullet set up would reduce BB height and pedal to ground clearance while also slackening both the effective seat and head tube angles.
The fork will also fit a 27.5+ tire, however, this is highly discouraged as the BB drop would become dangerously low. We recommend staying ready for business with 29" all-round. -
Can I use a different rear shock?
Most 230mm x 65mm Trunnion Mount shocks should fit. The leverage curve can work well with a coil shock. However, it’s worth noting that Polygon have Fox tune the stock rear shocks to work best with the specific bike model, so a standard tune replacement shock may not offer optimized performance.
-
Can I change the fork?
The standard forks are 170mm travel, you cannot use a dual crown fork as the frame is not designed or tested to withstand the different loads.
-
Can Collosus N9 fit a chain guide?
For sure, the bike comes equipped with an e13 TRS+ Bashguard. The chain guide mounts directly to the drive unit and the bolt pattern is different to traditional ISCG/05, so most ‘normal’ chain guides are not compatible.
-
What size rotors can I use?
You can run up to 220mm rotors front and rear. While you can downsize from the standard 203mm to 180mm, we suggest not to.
