The Supercaliber SLR 9.8 XT is an ultra-light 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 lay-up 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 110 mm fork and 80 mm of IsoStrut rear suspension to smooth your roll without kicking pedalling efficiency to the wind. It's all topped off with carbon wheels, a carbon cockpit and Shimano's trail-trusted XT drivetrain.
