The 2019 Specialized Butcher Black Diamond 2 Bliss Ready Tyre is the latest generation of the World-Cup-proven intermediate tyre. The Butcher BLCK DMND 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, the proprietary GRIPTON compound improves high frequency damping, attaching the tyre to the ground better on both small bumps & rough sections. The low frequencies of the rolling tyre deflections pass through unfiltered, leaving no energy absorbed, keeping speed high. Once you ride the Butcher, you'll never want another tyre for your gravity excursions. The new BLCK DMND casing strikes the balance between suppleness & extreme pinch flat protection. In order to descend all-out, you need as much traction as possible—the tyre needs to conform & hold on to the ground, but also protect from pinch flats. In order for this to happen, only the treaded part of the tire needs to conform, grip, & dampen, while the tire base offers stability & support for steering inputs.
