This aluminum-framed multi-terrain bike excels across pavement, gravel, and unpaved surfaces. The composite fork absorbs vibrations for a refined ride quality, while an integrated flip chip enables quick geometry adjustments—shifting wheelbase and tire clearance to match your terrain and riding style.
Confident handling
Tuned compliance
Tapered seatstays with reduced wall thickness dampen road vibrations and impacts for a more compliant ride. The D-Fuse handlebar and seatpost form an integrated compliance system that absorbs chatter while maintaining lateral stiffness for powerful cornering, sprinting, and climbing efforts.
Adaptable to the terrain
The rear dropout flip chip provides two wheelbase configurations—compact for nimble handling and acceleration, or extended for high-speed stability and up to 53mm tire clearance. The included D-Fuse seatpost maximizes vibration absorption, with the option to swap in a standard 30.9mm or dropper post to suit your riding preferences and terrain demands.
