Tioga PowerBlock Tire-Wire-Black

The Tioga PowerBlock Tire-Wire-Black at J&R Bicycles is a hardworking lightweight racing tire built for speed and made available at a budget-friendly price. With the PowerBlock you get all the pro-performance of the S-Spec series but with a thicker and stronger sidewall with steel bead. Side lugs keep you in control around the corners while the smooth center tread offers less resistance on the straight track.
