POWERBLOCK

The Tioga Powerblock tire is a lightweight race tire with low profile directional side lugs for excellent cornering on hard pack surfaces and a smooth center tread for less rolling resistance.
All the sweet goodness of the PowerBlock S-Spec, but in steel bead with thicker, stronger sidewall. The standard PowerBlock strikes the sacred equilibrium between performance and value.
