Specialized's Purgatory GRID tire is the standard bearer for trail tire performance. By applying FE Analysis and our GRIPTON compound to the Purgatory, they've optimized this tread to be fast rolling and to bite hard on loose terrain. Meanwhile, the GRID casing provides the utmost in cut and flat protection at the sidewalls, And of course, the 2Bliss Ready design is the icing on the cake, allowing you to run lower tire pressures and all but eliminate the risk of pinch flats. - Casing: Additional sidewall protection for exceptional durability, plus sidewall stiffness for stability. - Bead: Foldable - Butyl wrapped bead, 2Bliss Ready - Compound: GRIPTON

The new 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. - Casing: 60 TPI - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - 650b x 2.3", PSI 25-50, approximate weight 825g - 650b x 2.6", PSI 20-40, approximate weight 950g - 650b x 2.8", PSI 15-30, approximate weight 1040g
