Where speed and trail tough cut-resistance intersect, you'll find our Fast Trak CONTROL 2Bliss Ready tire. It takes the legendary tread design of the Fast Trak a step further by manipulating each knob with Finite Element Analysis—creating more consistent shoulder blocks for better cornering traction, while also optimizing block spacing for better self-cleaning. The tread of this 2Bliss Ready version is also slightly wider compared to the S-Works version, which protects the sidewalls and delivers additional cornering bite. Our new CONTROL casing has a slight extension in the casing overlap to give the best prevention of pinch flats. Lastly, our proprietary GRIPTON® compound gives the tire a livelier feel and more grip in either wet or dry conditions. - Casing: 60 TPI - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON®

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 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
