No tire handles every XC race course like the Barzo XC Race, and it’s got multiple UCI World Championships to prove it. Its speed isn’t limited to any specific weather or surface. Rain and mud, sun and hardpack, roots and rocks – it doesn’t matter, the Barzo shreds it all. The alternating center knobs roll fast, and – despite the tire’s speed-focused pedigree – the moto-style shoulder knobs bite hard while cornering. Siping throughout increases grip under lateral loads, helping to maintain speed across terrain of all types, and spacious knob placement cleans muck and loamy soil.
