Nothing else like it
Supercaliber’s unique frame design ditches traditional suspension hardware so there’s less weight, less maintenance and less lateral flex. IsoStrut connects the mainframe to the pivot-less seat stays to offer about 60 mm of rear wheel travel. This design offers a unique blend of efficiency, traction and fatigue-fighting compliance that keeps racers fresh and in control.
OCLV Mountain Carbon
Trek's mountain-specific carbon is engineered to withstand the extreme demands of off-road racing. Advanced analysis allows our designers to create a frame with the best blend of light weight, responsiveness and just enough compliance in the seat stays to eliminate the need for a heavy rear pivot system.
Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.
Water bottle capacity
Space for two water bottles makes it easier to stay hydrated on long days.
Control Freak cable management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
