It's right for you if...
You live your life in 60-minute intervals, and know crisp autumn air means #CrossIsHere. You love Belgian beer, wake up at ungodly hours to livestream World Cup cyclocross races, and want the best cyclocross bike available—the same one ridden by the pros of the Telenet-Fidea Lions.
The tech you get
An ultra-lightweight 600 Series OCLV Carbon frame with Front and Rear IsoSpeed, a 1x11 SRAM Force CX 1 drivetrain, flat mount hydraulic disc brakes, and a Bontrager IsoCore carbon handlebar. Plus, lightweight Bontrager Paradigm Comp Disc TLR wheels that easily convert to tubeless so you can run a lower tire pressure without fear of flats.
The final word
In a race that lasts an hour or less, you don't have time for things to go wrong. You get a lot with our top-of-the-line cyclocross bike— a lightweight OCLV Carbon frame, cross-specific design details, and Front and Rear IsoSpeed for efficiency and traction over even the roughest courses—but you're really paying for the peace of mind that you're riding the best.

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.
