Tioga | PowerBlock S-Spec Tire - 120 TPI

Called by many the ultimate BMX race tire — the PowerBlock turns rider input into forward motion so you roll faster with less wasted energy. The S-Spec uses Tioga's thinnest sidewall for max suppleness and weight savings. Size for size, it's the lightest BMX tire in the world.

  • CYLEX 120 TPI superlight casing
  • UTC rubber compound
  • Block center tread for traction and low rolling resistance
  • Folding bead

Ships from our Apple Valley, CA shop.
