COLLOSUS DH9
Features
-
Multiple setup possibilities
The Collosus DH offers 4 geometry configurations using two flip-chips. Riders can fine-tune the bottom bracket position for either a mullet setup with a 27.5” rear wheel or a full 29er configuration. When using a smaller rear wheel, set the flip chip in its tallest position to maintain rear center height. Switching to a 29” rear wheel allows the frame to drop down, ensuring a consistent riding position across wheel sizes.
-
Dial In Your Perfect Geometry
With a 1.5” headset, riders can further customize their ride by fitting aftermarket angle-adjust cups, dialing in the perfect geometry for their style and terrain.
-
No Compromise
Our innovative 6-bar independent floating suspension is engineered to control wheel path and anti-squat independently to the leverage curve, ensuring optimal performance across varied terrain.
-
UDH Compatibility for Next-Gen Shifting
With the UDH dropouts, the Collosus DH is now compatible with T-Type drivetrains for seamless integration with modern shifting systems.
