The latest generation of the World-Cup-proven intermediate tire, the Butcher 2Bliss Ready, receives sawtooth faces on the tread blocks to increase stability under load and provide additional biting edges. This in turn improves rolling speed as well as control under hard braking and cornering. 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, keeping speed high. Once you ride this new Butcher, you'll never want another tire for your gravity excursions. - Casing: 60 TPI - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - 650B x 2.3" PSI 25-50; approximate weight 760g

The Butcher GRID GRAVITY 2Bliss Ready T9 is the perfect choice for trail and gravity riders. Ramped and siped center tread blocks provide strong traction and accurate steering, while the shoulder knobs offer a continuous biting edge for railing through fast corners.

Building on this solid base, the high-dampening T9 GRIPTON compound rebounds slowly to grip and stick to the ground for total traction and control. - 650Bx2.3", psi 25-50, approximate weight 1050g - 650Bx2.6", psi 20-40, approximate weight 1200g - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Casing: 60 TPI, Dual-Ply - Compound: GRIPTON T9
