Supercaliber SLR XT - Trek

Supercaliber SLR XT is an ultralight XC mountain bike that's ready to lay down rubber on race day. Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus layup that gives you all the stiffness you crave, and none of the weight. XC courses get rowdier every year, so it's equipped with a 110mm fork and 80mm of IsoStrut rear suspension to smooth your roll without kicking pedaling efficiency to the wind. It's all topped off with carbon wheels, a carbon cockpit, and Shimano's trail-trusted XT drivetrain.
