You’re after tires that allow you to lean in and push harder on the bike. Tires that give you the ability to forget them so you’re fully concentrated on you and what you need to do. Zipp’s race-specific Tangente R25 Speed tires provide the crucial tools riders demand from high performance 700x25 width tires: superior durability, rolling resistance, and cornering grip.

Zipp is committed to offering a high-performance race tire at the 25mm width at the go-to width for road cyclists and triathletes on rim brakes. The Tangente Speed R25 tires are major upgrades over Zipp’s previous 25mm-wide 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.

Beyond this, the Tangente Speed R25 tires also have improved puncture resistance. The Speed R25 (designed as a race tire) features a 220 TPI nylon casing for an extra supple ride. We take no short cuts in development and you’ll see at the end of your ride, recovery drink in hand, just how hard you can push yourself when you only have to consider you.
