The latest generation of the World-Cup-proven intermediate tire, the Butcher GRID TRAIL 2Bliss Ready, receives an entirely new tread pattern. Wider shoulder knobs better support load under hard cornering, while the biting edges of the shoulder knobs are moved further inside, and the center blocks have been staggered and spaced better for a smoother transition when leaning the bike over. Meanwhile, our proprietary GRIPTON compound improves high-frequency damping, attaching the tire to the ground better on both small bumps and rough sections. The low frequencies of the rolling tire deflections pass through unfiltered, leaving no energy absorbed and keeping speed high. Once you ride the Butcher, you'll never want another tire for your gravity excursions. Our new GRID TRAIL casing is stiffer, delivering better handling at lower pressures—all while increasing pinch flat protection by 15% and puncture protection by 30%.
