Vittoria Corsa Evo CX Tubular Tire
The king of tubular tires, the Vittoria Corsa Evo CX, now comes with an unbelievable 320 TPI Corespun K casing made from alternating Polycotton and Kevlar threads. More TPI means a more supple ride, no matter what PSI you prefer. Vittoria's Compressed Wrap makes use of the highest grade of Corespun casing cord and rubber compounds, resulting in a casing that allows the Polycotton and Kevlar threads to act independently, which reduces surface deflection and rolling resistance while maximizing puncture resistance. The victory list of the Corsa CX is spectacular, and folks who choose to race on tubies demand the CX more than any other tire we sell. Its herringbone tread pattern provides an ideal combination of traction and low rolling resistance thanks to its Twin Tread Technology where harder tread is placed in the center of the tire where the wear occurs, and a softer compound is used on the shoulder for better grip. A thin, lightweight PRB puncture resistant belt is placed immediately beneath the tread to achieve maximum puncture protection while maintaining low rolling resistance. A latex inner tube further adds to the puncture resistance and also lessens the rolling resistance over butyl rubber tubes. The tread is built with a silica enhanced Kevlar Carbon 3D SiO2 compound to give their tires longer wear life and supreme grip. It's available in 700x21c and 700x23c sizes and has a 42mm presta valve.
