Polygon Collosus T8 CB - 2026

The Modern Trail Workhorse Where precision meets aggression, and every trail meets its match. As trails get steeper, rougher, and wilder, the bikes we ride must rise to match. The Collosus T Series rises to meet this new era of aggressive trail riding. Performance wise, it’s it’s lighter and more nimble than the enduro-focused Collosus N, yet more confident and capable on descents than the versatile Siskiu T. Born from the chaos of modern trails, it’s built to charge harder, corner deeper, and descent confidently. Features Geometry You Can Dial In Riders can adjust the bottom bracket height and switch between 29” and mullet setups using the rear wheel and shock mount flip chips. Additionally, half-spherical headset bearings allow precise head angle tuning (+/-0.75°) for optimal adaptability across any terrain Compact and Robust IFS Linkage Design The heart of the IFS system lies in the twin link at the base of the seat tube. On the Collosus T, the compact IFS uses separated links for greater flexibility while maintaining anti-squat performance. This placement also increases rear triangle stiffness for sharper handling and better control. PolyPocket frame storage Our proprietary PolyPocket keeps your essentials secure and within reach. The insert bag attaches with a Velcro backing for a rattle-free fit, includes a stopper to prevent sliding toward the bottom bracket, and integrates cable guides for a clean, organized look. 29/ MX Compatible With the UDH dropouts, the Collosus T is now compatible with T-Type drivetrains for seamless integration with modern shifting systems.
