Trek has been doing 29ers quite awhile, so they know and a thing or two about making a great 29er hardtail. The X-Caliber 7 uses a sleek, light Gold Series aluminum frame features Gary Fisher's 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 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.

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.
