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.

Trek's G2 Geometry (version 2 of Gary Fisher's Genesis Geometry) delivers the ultimate ride for every trail. Genesis earned rave reviews for awesome handling on climbs and descents thanks to a long top tube paired with a short stem that moves the front wheel forward for top-notch confidence and control, while short chainstays add phenomenal traction. G2 Geometry takes these handling traits to the next level by boosting control on tight singletrack and technical climbs, too. This is accomplished by increasing the amount of fork offset (reducing trail), which makes G2 bikes steer more quickly, and by shortening the reach, which puts more weight on the front wheel for even better control and confidence. The two animations above showcase how G2 Geometry provides the perfect ride.
