The S-Works Fast Trak 2Bliss Ready T5/T7 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. The S-Works casing is our lightest and most supple construction, shaving every gram possible from rotational weight. To top off this premium build the T5/T7 dual compound uses T5 center knobs for minimal rolling resistance and T7 shoulder knobs for extra cornering grip. - Casing: 120 TPI, lightest and most supple XC race construction - Bead: Foldable. - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON T5/T7 - 29 x 2.2", PSI 25-50, approximate weight 575g - 29 x 2.35", PSI 25-50, approximate weight 615g
