Riders have been asking for a tire that can enhance speed while also giving them confidence while cornering. & by lowering the center tread of the Slaughter Control 2 Bliss Ready tire for high speed while keeping plenty of knob edges for secure braking the result is getting you to the bottom first. This tire also features much taller side knobs that provide confident cornering traction. Weve found that its proper for rear usage but it can also be ridden as a front.
