The XCO World Champion tire Riding technical XC? The Barzo is the choice of the 2015 World Champion, as well as the winner of the BC Bike Race. How can such an aggressive XC tire roll so fast? The magic starts in the center 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 tire that corners as fast as it rolls, while still offering the protection of a full depth tread. Rocks and roots? Check. World Championship? Check.

When you want more speed on dry surfaces and are unwilling to compromise cornering ability, Vittoria's Mezcal G+ is your tire. The center ridge made of tightly spaced, low-profile knobs keeps you rolling fast and transitions cleanly into legit side knobs that tear into both hard and soft corners. The Mezcal offers hundreds of multi-directional biting edges across the tread for relentless climbing traction as well as reliable braking. And, you can forget about the usual speed versus handling tradeoffs, because Vittoria’s G+ Isotech compound firms up on the straights for blazing speed, and softens when dynamic forces are applied to the tread, such as when braking, accelerating, or cornering. This means race-winning speed, and fun-soaked berm carving, all adding up to a versatile and fun tire that gets down to business.
