Description
COLLOSUS DH: Adjustable Geometry and Race-Proven Technology for Gravity Riding
We never really left the DH scene, we just took the time to get it right. Born from the DNA of our EDR-proven COLLOSUS N enduro bike and tested for two seasons by the PFR team, the COLLOSUS DH mountain bike has been engineered to meet the demands of modern, aggressive riding. Proven at some of the biggest Freeride events such as Darkfest and Red Bull Rampage, versatility is at the core of the COLLOSUS DH. With an adjustable flip-chip system offering four geometry setups, riders can seamlessly transition between a stable 29er race machine and a flickable mullet set-up for the bike park. If you're looking for a long-travel gravity bike that balances precision engineering with pure riding enjoyment, your wait is over.

Features
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.

Switchable between 29” and MX setups with easy-to-use seatstay flip chips. No extra parts needed to get your party in the back setup.

A 1.5” headtube allows riders to further customize reach by fitting aftermarket cups, along with a high/low BB position flip chip for fine tuning your ride style.
