Vittoria's Morsa G Plus TNT 27. 5in Tire effectively adds wings to your DH bomber. Featuring a bold open tread and squared off knobs, this tire provides mountains of grip for any enduro or downhill shred session in a multitude of conditions. As an added bonus, ramped leading edges on the knobs reduce rolling resistance for more speed when gravity's not doing the work. The Morsa G Plus incorporates Vittoria's TNT casing, which is compatible with both tubes and sealant based tubeless systems and enforced with a Kevlar bead and sidewall protection. This tire also boasts the revolutionary new G Isotech compound, utilizing graphene within the compound mix to reduce rolling resistance and overall weight, increase durability, and improve grip in wet weather compared to tires without the G Isotech compound.
