Supercaliber SLR 9.9 XTR is an ultralight carbon XC mountain bike equipped with the top components for 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 comes 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 lightning-fast shifting from Shimano's all-new iconic XTR Di2 wireless drivetrain.
