Zipp (USA) – “Zipp is proud to enter the tubeless road tire market as the top performer with the new Tangente Speed RT25 and Tangente Speed RT28. The new tires will be available in June and August respectively.”

Zipp’s Tangente Speed RT25 and Tangente Speed RT28 tubeless tires deliver the lowest rolling resistance, best dry and best overall corning grip among major brands, according to testing at an independent lab. Zipp’s Tangente Speed RT25 and RT28 are performance and race-oriented tires designed for on-pavement riding.

The new tubeless tires were modeled after Zipp’s pioneering wide road clincher tires, the Zipp Tangente Speed R28, Tangente Course R28 and Tangente Course R30. These tires feature low rolling resistance and high durability. The new tubeless Zipp Tangente Speed RT25 and RT28 feature the same tread pattern as these groundbreaking clincher models.
