The latest generation of the World-Cup-proven intermediate tire the Butcher GRID 2 Bliss Ready receives sawtooth faces on the tread blocks to increase stability under load & provide additional biting edges. This in turn improves rolling speed as well as control under hard braking & cornering. Meanwhile our proprietary GRIPTON compound improves high frequency damping attaching the tire to the ground better on both small bumps & rough sections. The low frequencies of the rolling tire deflections pass through unfiltered leaving no energy absorbed & keeping speed high. Once you ride the Butcher you will never want another tire for your gravity excursions. We recommend GRID tires for anyone seeking the utmost in flat & sidewall protection or additional stability.
