The Fast Trak Sport has become synonymous with fast and lightweight tires that are able to handle the most technical courses and the most grueling conditions. This model redefines what was thought possible with a cross-country tread design. Our Block-In-Block design uses a taller adaptable inner block to pierce the ground and claw for traction. The larger outer structure supports the inner block for additional speed, traction, support and stable handling. Adding to this, the Fast Trak profile and knob spacing has been optimized for a wide variety of internal rim widths. - Casing: 60 TPI - Bead: Wire - Compound: 60a

The all new Hillbilly GRID 2Bliss Ready tire is a perfect option for front tire 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 and better connect you to the trail. Small surface center knobs also increase the load on the ground and help surface penetration, while the shoulder knob row provides support in fast turns on all surfaces. 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: Additional cap ply for exceptional durability, plus added sidewall stiffness for enhanced stability. - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - 650b x 2.3" PSI 2550; approximate weight 900g - 650b x 2.6" PSI 2040; approximate weight 985g

The latest generation of the World-Cup-proven intermediate tire, the Butcher GRID TRAIL 2Bliss Ready, receives an entirely new tread pattern. Wider shoulder knobs better support load under hard cornering, while the biting edges of the shoulder knobs are moved further inside. The center blocks have been staggered and spaced better for a smoother transition when leaning the bike over. Our new GRID TRAIL casing is stiffer, delivering better handling at lower pressures, all while increasing pinch flat protection by 15% and puncture protection by 30%. Meanwhile, our proprietary GRIPTON compound improves high-frequency damping, gripping the tire to the ground better on both small bumps and rough sections. The low frequencies of the rolling tire deflections pass through unfiltered, leaving no energy absorbed and keeping speed high. Once you ride the Butcher, you'll never want another tire for your gravity excursions. - Casing: Additional bead to bead protection for exceptional durability plus sidewall stiffness stability - Compound: GRIPTON - Pressure: 25 – 50psi - Folding bead - 2Bliss Ready
