Vittoria's Open Corsa Evo CX is a top-notch clincher with a great ride. This lightweight tire features an incredible 320-thread-per-inch casing for awesome road response and feel. In fact, the high TPI count allows you run pressures up to 200psi! Plus, its twin-tread compound places a hard, long-wearing and quick-rolling compound in the center and a softer, tackier compound on the sides for cornering confidence on all surfaces and at all speeds. This great tire also features Vittoria's excellent Puncture Resistant Belting so you can stop worrying about flats!
