Trek Supercaliber SLR 9.8 XO AXS

The Supercaliber SLR 9.8 X0 AXS is an ultra-light XC mountain bike that's built with the top components for 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 dropping pedalling efficiency. It's all topped off with carbon wheels, a carbon cockpit and SRAM's wireless direct-mount X0 transmission.
