The latest generation of the World Cup-tested tire, the Butcher GRID Trail 2Bliss Ready, features a completely new tread pattern. Wider shoulder knobs enhance cornering grip during hard turns, while the edges of the shoulder knobs have been moved further inward. The center knobs are staggered to ensure a smooth transition when cornering. Additionally, our proprietary Gripton® rubber compound improves high-frequency damping and keeps the tire better grounded on both small bumps and rough sections. Low frequencies during rolling are transmitted without filtering, allowing no energy absorption and maintaining high speed. Once you've ridden with the Butcher, you'll never want another tire for your trail rides. Casing: 60 TPI, lightweight yet robust with added bead-to-bead protection for exceptional durability, sidewall stiffness, and stability. Folding tire bead. Bead wrapped in Butyl = 2Bliss Ready.
