Vittoria's Mezcal III G2. 0 XC-Trail Tire is a fast rolling mountain tire that adds an injection of speed to any ride or race. Featuring a densely packed, low profile knob configuration and an alternating center-ridge tread, you'll reap the benefits of improved efficiency on smooth hardpack and demanding singletrack alike. This version of the Mezcal incorporates Vittoria's XC-Trail TNT construction, which is compatible with tubes and, thanks to its folding aramid bead, sealant-based tubeless systems as well. It's constructed of a 120TPI nylon casing for light weight with an additional sidewall protection layer so your ride isn't cut short because of well, a sidewall cut. This tire also boasts Vittoria's new Graphene 2. 0 compound using 4 separate durometers for the best combination of wet grip, rolling resistance, cornering stability, and longevity. Graphene 2. 0 basically takes the original Graphene compound foundation that Vittoria previously used, and improves upon the metrics in every conceivable category.
