BARZO XC RACE: World Championship proven tread combined with XC Race Compound for coarse loose terrain Riding technical XC? The Barzo is the choice of the XC World Champion's, as well as the winner of the BC Bike Race. How can such an aggressive XC tyre roll so fast? The magic starts in the centre tread, where we place an alternating ridge design, and progressive sipe angles. Cornering duties are handled by the moto-style block knobs, laid out in a proven V-formation. The result is a tyre that corners as fast as it rolls, while still offering the protection of a full depth tread. Rocks and roots? Check. World Championship?
