Want to add some color to your bike? Make your rivals see red with our anodized red oval aero chainrings for your compact cranks. Red Q-Rings feature the same wind-shucking, subtle but efficient 10% ovality as our standard aero Q-Rings. Designed to boost your cycling performance by varying drivetrain resistance inline with your legs´ natural strengths and weaknesses when pedaling, red Q-Rings with a 110BCD take advantage of the most-productive part of your pedal stroke by working with your body´s biomechanics to yield maximum efficiency. Choose from 5 Optimum Chainring Positions (OCP) to fine-tune your improved riding experience and go further and faster with less fatigue.
