2015 Trek X-Caliber 6 Is Packed With Features and Looks Great!

Caution: X-Caliber will get you hooked. 

It packs all of Trek’s XC race hardtail experience into a light, fast, race-ready bike that pairs the right wheel size with each frame size.

Trek's X-Caliber 6 is ready for big-time on- and off-road fun with its super-light, nimble aluminum frame that features Gary Fisher's G2 Geometry for superior cornering, climbing and descending. Adding to those attributes is a 100mm-travel suspension fork and a 29-inch wheelset for smoothing the trails and getting you over the roughest terrain with complete control. Plus, component highlights include a precision-shifting SRAM 27-speed drivetrain, a host of Bontrager parts and even Shimano hydraulic disc brakes for awesome stopping power in all conditions.
