Details
DIALED FOR MORE
Built for riders who want more confidence on steeper, rougher trails without going full enduro. With 160/140 mm travel, adjustable geometry, and a modern alloy chassis, the Collosus T Alloy stays efficient on climbs and feels planted and composed when it’s time to push harder downhill.
IFS 6-BAR LINKAGE DESIGN
This suspension platform separates wheel path, leverage curve, and anti-squat for refined kinematics. It combines small-bump sensitivity with strong mid-stroke support to maintain traction and deliver a more composed, deeper-travel feel than you’d expect from 140 mm out back.
PLATFORM HIGHLIGHTS
Oversized pivot hardware and wide bearings add torsional stiffness and a more precise chassis feel on rougher trails. PolyPocket frame storage keeps essentials secure inside the frame, while flip chips and adjustable headset cups let riders fine-tune geometry.

As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.
Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.
Please follow the video playlist below to complete the setup of your new bike correctly.
