Sneak it into a cross bike, fit it into a road frame, the overall wheel diameter stays the same as a 700 x 30mm road tire. Ride it on tarmac, take it to the dirt as well. Creating a new riding experience, regardless of where your exploits lead you.

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. - Aggressive XC tread for the most technical terrain - Medium spaced knobs for a range of terrain and conditions
