Trek Supercaliber SLR 9.9 XX AXS Gen 2 - 2025
Details
Supercaliber SLR 9.9 XX AXS is an ultralight 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 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 dropping pedaling efficiency. It's all topped off with carbon wheels, a carbon cockpit, and SRAM's lightest wireless direct-mount transmission.
