The FASTR-X is our most versatile race tire to date. Increased strategical placement of Grip-Pods matched to multi-facet Nano Knobs on shoulder and sides, capped off with friction enhancing chemical etching over the central tread, FASTR-X strikes the rarefied balance of speed and control like none before.
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.
