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. Or, you're seeking a light, fast platform for a carbon gravel bike.
The tech you get
An ultralight 600 Series OCLV Carbon frame with Front and Rear IsoSpeed, integrated cartridge bearing headset, and cable stops. Boone is 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 both Front and 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 & 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.
