It's right for you if...
You're lining up every weekend to race, and you're looking to build up a lightweight cyclocross bike (or a really sweet pit bike) so you can spend more time doing what you love: getting muddy and winning races.
The tech you get
A svelte, ultra-lightweight 600 Series OCLV Carbon frame with Rear IsoSpeed, an integrated cartridge bearing headset, internal cable routing, and a T47 threaded bottom bracket. Plus, a full carbon Trek Cross fork. Designed for 12mm thru axles and flat mount disc brakes.
The final word
There are a lot of carbon cyclocross frames out there, but there's only one with Rear IsoSpeed. Boone soaks up the fatiguing bumps in a 'cross course so you'll stay stronger longer and have enough energy after your race to party.

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.
