Vittoria Corsa Evo CX Tubular (320 TPI)

The Vittoria Corsa Evo CX has already established itself by winning countless races all over the world and now it is even faster and tougher. First, Vittoria upgraded to a true 320 TPI corespun polycotton casing for a durable and incredibly supple ride even at high pressures. The PRB 2.0 puncture resistant barrier incorporates very thin yet strong Aramid fibers crossed at different angles for an incredibly tough tire without sacrificing low weight and supple ride feel. Kevlar SiO2 3D tread compound with added silica and microscopic Kevlar® fibers provides excellent grip even in wet conditions and low rolling resistance while maintaining a respectable tread life. Twin Tread technology places a harder compound in the center tread for low rolling resistance and a softer compound on the shoulders for better grip while cornering. 42mm removable smooth presta valve threads into the tire right at the base tape allowing the use of in-line valve extenders or specially designed replacement valves. 115 to 200 PSI. All black. Sizes 700 x 21mm (21-622 ISO; 245 grams) or 700 x 23mm (23-622 ISO; 250 grams).
