The Open Cross Evo XG cyclocross tire is Vittoria's pro-quality option for riding and racing in loose and muddy conditions. Just like Vittoria's high end road tires, the XG uses a Kevlar 3D compound for flat-resistance, a PRB puncture resistant belt beneath the tread, and a cotton casing for a supple ride. Black sidewalls with a sharp-looking silver tread. 700x32.
