The Tioga Powerblock S-Spec Tires are considered by many to be the ultimate BMX racing tire. The Powerblock is designed to optimally transfer pedal power into forward motion while providing maximum traction on pavement or dirt corners. The S-Spec version utilizes Tioga's thinnest sidewall and a folding bead for maximum suppleness and weight savings. In short, the Powerblocks are staple in the racing world and the S-Spec version steps things up to provide more weight savings.
