When you wield the X-Caliber 7, your kingly rides will become legend. Trek uses a sleek, light Gold Series aluminum frame featuring their ride-enhancing G2 geometry for superior cornering, climbing and descending. Adding to those attributes is a set of steamrolling wheels and a 100mm-travel fork that smooths the trail and steers you through the roughest terrain. Component highlights include a Shimano 27-speed drivetrain, and Shimano disc brakes that give you awesome stopping power in any and all conditions. And with Trek's Smart Wheel sizing, you're riding the fastest wheels with the best possible fit.
