The Specialized Hillbilly BLCK DMND 2 Bliss Ready Mountain Bike Tyre is a perfect option for front tyre use when the course features intermediate to soft terrain. When the soil is changing from hard to soft, the small blocks penetrate the ground surface & better connect you to the trail. Small surface centre knobs also increase the load on the ground & help surface penetration, while the shoulder knob row provides support in fast turns on all surfaces. Specialized’s GRIPTON compound, meanwhile, improves high frequency damping, better attaching the tyre to the ground over small bumps & rough sections alike. This means that the low frequencies of the rolling tyre deflections pass through unfiltered, leaving no energy to be absorbed & keeping your speeds high. 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 tyre needs to conform, grip, & dampen, while the tyre base offers stability & support for steering inputs.
