The all new Hillbilly GRID 2 Bliss Ready tyre is a perfect option for front tyre use when the course features intermediate to soft terrain. When the terrain 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 GRIPTON compound meanwhile improves high frequency damping better attaching the tyre to the ground over small bumps & rough sections alike. This also means that the low frequencies of the rolling tyre deflections pass through unfiltered leaving no energy to be absorbed & keeping your speed high. Please note that we recommend GRID tyres for anyone seeking the utmost in flat & sidewall protection or additional stability. > Casing: Additional cap ply for exceptional durability plus added sidewall stiffness for enhanced stability. > Bead: Foldable > Butyl wrapped bead = 2 Bliss Ready > Compound: GRIPTON > 650b x 2.3; PSI 2550; approximate weight 900g > 650b x 2.6; PSI 2040; approximate weight 985g
