It's ready for any build you can imagine for your XC pursuits

"Transitions from pavement to the Crockett’s off-road habitat have gone smoothly thanks to damping on par with some of the smoothest cyclocross bikes I have reviewed. I was able to keep my lines and get traction in the saddle through the transition and on some bumpy straightaways."

Podiums and breakout performances at the best party in cyclocross, bar none.

Reliable stopping power in all conditions, including wet and muddy.

Control Freak is the lightest, quietest, most versatile cable management system. It allows any combination of shift and brake housing to be routed through the frame for clean aesthetics and an easily customizable set up.

It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimizes the wheelbase.

Trek’s premium-grade aluminum is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.

How tall are you?

To measure your height, stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inseam?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
