RS01E, 2.3mm, 180-223mm

We took the world by storm in 2020 by developing, racing, and winning the UCI World Cup Overall in Elite Female, the Jr. World Championships, and a Silver in Elite Men’s with our 2.3 mm rotor technology. The RS01E rotor is stronger, reduces brake fade, and lowers vibration more than any other on the market. Say goodbye to bent and noisy rotors.
