Zipp is committed to offering pro-level 25mm tires, the go-to width for road cyclists and triathletes, especially those on rim brakes. The Tangente Course R25 is a major upgrade over Zipp’s previous 25mm-wide offering 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.

Beyond this, the Tangente Course R25 tires also have improved puncture resistance. The Course R25 (a race or training tire) features a nylon puncture protection strip between the tread and its 120 TPI nylon casing. If you’re after tires that allow you to lean in and push harder on the bike, and tires that give you the ability to focus on your actions, not your tires, this clincher tire is a great choice. Zipp’s Tangente R25 Course tires, designed for training or competition, provide the crucial tools riders demand from high performance 700x25 width road tires: superior durability, low rolling resistance, and cornering grip.
