Features

• The new Worlds Fastest Tire. More than 37 seconds faster over a 40K time trial than our closest competitor

• For higher performance, racing purposes only. Not intended for everyday use or training.

• 220 tpi casing provides ultra low rolling resistance and excellent ride quality

• CFD-aided tread profile for better aerodynamics on contemporary rim widths

• Aero wings help slice through the wind
