Lean in and push harder
Designed for training or competition, Zipp's Tangente R25 Course tires provide the crucial tools riders demand from high-performance 700x25 width tires: superior durability, rolling resistance, and cornering grip.
In line with the brand's commitment 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 its predecessor.
For starters, Zipp used a more advanced durometer rubber, almost 12 months in development, for lower rolling resistance while also gaining improved cornering grip and tread longevity. The enhanced longevity and performance were confirmed by internal testing showing that both rolling resistance and grip actually improved in the first 100 miles as the tire breaks in.
Beyond this, the Tangente Course R25 tires also have stronger puncture resistance thanks to a nylon puncture protection strip between the tread and its 120 TPI nylon casing.
Zipp took no short cuts in the design and development of the Tangente Course R25 tires and the result is a must-have upgrade that will guide you swiftly and safely to the finish line in record time.
