The Vittoria Mezcal G Plus 27. 5in TNT Tire brings smooth rolling speed to your weekend trail adventures. It features an almost continuous center ridge for efficiency on smooth hardpack and moderate side knobs to hook up in the corners and rail berms in soft or loose terrain. The Mezcal G Plus incorporates Vittoria's TNT casing, which is compatible with tubes and sealant-based tubeless systems and reinforced with a KEVLAR bead and sidewall protection. This tire also boasts Vittoria's revolutionary G+ Isotech compound. G+ Isotech involves the addition of grapheme, cycling's latest wonder material, to reduce rolling resistance and overall weight, increase durability, and improve grip in wet weather compared to tires without the G+ Isotech compound.
