ROTOR CHAINRING Q 50AT – BCD110/113×5 – 11S – OUTER – BLACK – AERO

There’s no need to swap out your cranks to accommodate Q rings, ROTOR has Q’s for your Campagnolo cranks. In addition to biomechanical performance, there was one more important factor when designing Q rings: compatibility. We wanted everyone to be able to ride Q rings so we designed special Q´s for cranks requiring a specific bolt pattern. Oval chainrings feature subtle but efficient 10% ovality where the smallest diameter is at the weakest point of the pedal stroke and the maximum diameter at the strongest point of the pedal stroke.
