Tioga PowerBlock — 60 Tpi, Wire Bead

Overview

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