Rotor Q Rings BCD110x5. Oval chainrings featuring subtle but efficiente 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.

Road /TT Outer Aero and Inner Rings

Q Rings offer 5 Optimum Chainring Positions (OCP) that can be adjusted to take advantage of the pedal stroke´s most-productive zone. You could pedal more efficiently if only you could take greater advantage of your maximum power effort while lessening the time spent in the dead spots of a pedal rotation.
