Specialized Slaughter Grid 2br Tire Black 650b X 2.3 for sale online eBay Purgatory Grid 2BR T7 Mtb Bereifung Specialized IBKBike Cycling Shop GROUND CONTROL GRID 2BR Multibike Slaughter GRID 2Bliss Ready Opony 29 Opony MTB greenbike.pl. The Slaughter GRID 2Bliss Ready tire has been designed for heavy pedal, hard pack riding,receiving vertically stepped knob shapes for more knob core stability and additional biting edges. Fast courses on hard packed ground require a light, fast tire center to keep speeds high, but must also keep the speed through loose sandy corners and track well under hard braking. For these reasons, we've kept the high shoulder knobs. Our GRIPTON compound, meanwhile, improves high frequency damping, better attaching the tire to the ground over small bumps and rough sections alike. This also means that the low frequencies of the rolling tire deflections pass through unfiltered, leaving no energy to be absorbed and keeping your speed high. Please note that we recommend GRID tires for anyone seeking the utmost in flat and sidewall protection or additional stability.
