Trek Supercaliber - XTR Custom - 2026

***This is a custom one off build - Steerer tube will be cut to custom size once purchased for that perfect fit.***

Supercaliber 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 120mm 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 Shimano XTR 12s groupset.
