The Mezcal XC Race is built using a new XC Race Formulation and has been torture tested at the UCI elite levels. The Race Formulation employs Graphene and Silica, providing increased wet grip and suppleness, and combines a 60TPI tubeless ready casing to optimize deformation. This combination has been shown to reduce rider fatigue while simultaneously increasing race-day reliability. The continuous center line maintains fast-rolling contact, and its offset extensions are siped to multiply the number of leading and trailing edges, propelling you up the trail on climbs and increasing bite while braking. The rear siping on the shoulder knobs runs parallel to the trail with variable widths and open trailing edges, so the Mezcal corners fast on hard, slippery surfaces – despite being such a fast-rolling tire. For climbing, cornering, or careening down hill, no tire cooks like the Mezcal. Race Formulation: Graphene + Silica Compound provdes speed and grip without compromise. Designed to be the absolute fastest option from point A to point B. 60 TPI Nylon Casing provides a supple feel with dependable nylon construction, providing reduced rider fatigue and increased race-day reliability. Kevlar Bead with Tubeless-ready technology ensures easy inflation and dependable air retention. Hookless Compatible.
