The Tioga Fastr React BLK LBL (Black Label) tire is a low-profile race tire with serrated-like knobbies to maximize grip during hard gate starts, a smooth centerline and pressure-sensitive side tread that increases corner traction when pushed to the limits. This design allows the tire to maintain minimal rolling resistance throughout the race without negatively affecting corner grip. The React BLK LBL is finished off with a Cylex 120 tpi casing, an Avntguard cut protection layer to help prevent flats, lightweight folding bead and a Pneumax 110psi high-pressure casing.
