Vittoria Cross EVO XN Tubular Cyclocross Tire. When race day arrives and the cyclocross course is dry and firm, the Vittoria Cross EVO XN tubular tire is just what you need for blazing fast performance. Its diamond tread pattern rolls super fast while the minimal edge knobs provide just enough bite for cornering. The Cross EVO XN features a Corespun 320 TPI casing with a latex inner that provides maximum suppleness without compromising durability for optimal handling and traction. Additionally, its 700x31 size meets the width requirements of UCI level cyclocross racing if one happens to compete at that level.
