Features
Smooth control
An extra curve above the dropout in our swept-leg design creates a smaller angle to the direction of road vibrations. This angle increases fore/aft compliance, better positioning the fork leg to absorb road force rather than transmitting it straight to the rider. We’ve also increased fork lateral stiffness, maximizing both smoothness and control.
All-new race geometry
With our pro racers' input, we’ve dialed in a race-tuned geometry that can dominate on the most challenging terrain and win at the world-class level. You get stiff power transfer, Incredible stability, and nimble handling in just the right combination.
Stop on your own terms: disc or canti
You’ve got a preference so we give you a choice: All-weather disc brakes or lightweight cantis.
Massive tire clearance
Mud is a given in cross, but effectively dealing with it is the difference between winning and just finishing. We opened up the frame and fork to give you the most clearance possible so your race never bogs down.

Sizing & fit
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 Trek retailer.
