S-Spec tires utilize Tioga’s ultra-lightweight CYLEX 120 TPI casing. Feather light and super supple, S-Spec tires conform better to track surfaces for buttery smooth runs. Lightweight folding bead only.
The ultra-efficient design of FASTR unifies speed with control like no other tire. Ultra-low rolling resistance achieved through a smooth central tread. An ingenious pressure sensitive Grip-Pod system (patent-pending) that stays out of the way, minimizing momentum loss, while fully coming alive to maintain control when pushing through corners. FASTR is faster precisely for what’a there and what’s not.
