Zipp uses an advanced durometer rubber for lower rolling resistance, improved cornering grip and tread longevity. This enhanced longevity and performance was confirmed by internal testing showing that both rolling resistance and grip both actually improve in the first 100 miles as the tire breaks in. The Course R25 (a race or training tire) features a nylon puncture protection strip between the tread and its 120 TPI nylon casing.
