In the fastest conditions, on the smoothest dry hardpack, no tire flies like the Vittoria Terreno XC Race mountain bike tire. The tread, the casing, the compounds – everything is engineered for speed when speed is everything. The Terreno's revolutionary fish scale tread pattern rolls smoothly on straightaways and bites while cornering and braking, and the gradual transition from the center strip to the shoulder knobs takes the awkward bum-up out of cornering.
