You'll enjoy all your favorite trails even more with GT's Sensor 4.0! Its aluminum frame features GT Independent Drivetrain Suspension to float over obstacles for total control. It also pedals efficiently so you can rip down and up hills. You'll love the feel of the super-smooth RockShox fork and X-Fusion rear shock through the dicey stuff. Plus, the frame is a little more capable than a full-on XC bike, giving you confidence on harder trails. Contributing to the do-it-all platform, the Sensor is equipped with quality Alex wheels with grippy Maxxis tires, a precision-shifting FSA/Shimano 27-speed drivetrain, and Shimano's excellent hydraulic discs, too.
