Various road surfaces or weather conditions cannot deter you: the endurance-specific ERC 1100 wheels enable you to ride fast and stable. With AERO+ optimized rim profiles wider and more comfortable tires are better supported. Ultra low-friction SINC Ceramic bearings inside DICUT Aero hubs and the latest generation of DT Swiss aero spokes are technical highlights inside the wheels. The proven Ratchet EXP freehub system with its 36T Ratchets transfers each pedal stroke precisely into forward propulsion and speed from the start right to the finish of your ride.
