Oval Chainrings
Biomechanical studies show Q-Rings perform better than conventional chainrings. The effect is achieved by making the largest muscle groups in the legs more effective and eliminating dead center on kicking. Overall, this results in a much smoother and rounder ride, with less fatigue on the muscles. The biggest benefits of using the Q-Rings are the significant improvement in overall fitness through improved kick, greater sprinting capabilities through the elimination of dead center, slower muscle fatigue, and ultimately increased cardiovascular endurance for athletes.
During a submaximal test followed by a time trial over a distance of 1 km, it was demonstrated that the Q-Rings reduce heart rate and oxygen consumption while achieving 1.6 seconds better performance than round chainrings.

OCP
Optimum Chainring Position (OCP) stands for the variety of adjustments that Rotor Q-Rings offer to accommodate the specific riding characteristics of the rider. Q-Rings have up to 5 OCPs (Road) or up to 3 OCPs (MTB). These positions help to optimize your pedaling behavior.
You can choose your OCP if you know your optimal OCA, which you can determine through a Torque 360 ​​kick analysis with the Rotor 2INPower and INPower user software.
