The Vittoria Barzo mountain bike tire is a new addition to Vittoria's dirt line up, and features a medium depth moto-block tread that's ideal for XC racing on technical terrain. The alternating center-ridge reduces drag, with the sidewall knobs dig into the dirt for improved cornering traction. A lean dependent sipe angle improves traction in all weather conditions. The PRB 2.0 breaker delivers excellent flat protection, while the strong nylon casing gives a superior ride feel. The nylon bead keeps the tire firmly seated in the rim while reducing weight.
