The Tangente Speed R tires have major upgrades over Zipp’s previous offerings in vital qualities most important to road cyclists. For starters, Zipp uses a more advanced durometer rubber, almost 12 months in development, for lower rolling resistance while also gaining 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. Simply put, Zipp’s Tangente Speed R tires provide the crucial tools riders demand from high performance tires — superior durability, rolling resistance, and cornering grip.
