The latest generation of the World-Cup-proven intermediate tire, the Butcher GRID 2Bliss Ready, receives sawtooth faces on the tread blocks to increase stability under load and provide additional biting edges. This in turn improves rolling speed as well as control under hard braking and cornering. Meanwhile, our proprietary GRIPTON compound improves high frequency damping, attaching 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, keeping speed high. Once you ride this new Butcher, you will never want another tire for your gravity excursions. 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 870g - 650b x 2.6", PSI 20-40, approximate weight 960g - 650b x 2.8", PSI 15-30, approximate weight 1060g

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 Ground Control 2Bliss Ready is an exceptionally versatile trail tire. Not only does it feature improved cut-resistance, but we've also optimized the tread using FE Analysis. The end result is a tire that rolls fast and provides increased grip, traction, and confidence in every imaginable condition.

Specialized's Ground Control GRID is an exceptionally versatile trail tire. CAD engineered knob shapes strengthen knob structure for optimum braking and traction, but keep knob surfaces adaptable for best ground control. The GRIPTON compound helps make this the perfect choice for epic trail rides in any condition.
