ROTOR Q Ring Oval Inner Chainring - Shimano
The latest version of Rotor's popular Q Oval chainrings, compatible with all 4-bolt Shimano cranks including the R9100 and R8000. When mounted to Shimano cranks, the chainrings are set to intermediate position OCP3, which is the position most frequently used by road riders. For a perfect aesthetic integration with Shimano cranks, there is a set of bolt covers for the different crank models (available separately).
With Q rings you can ride further and faster with less fatigue because you are using your muscles more efficiently. Thanks to their oval shape, Q rings boost cycling performance by varying drivetrain resistance during pedaling inline with the legs' natural strengths and weaknesses. By orienting the narrowing diameter of the oval to the weakest point of the pedal stroke and the widening diameter to the strongest point of the pedal stroke, you can take full advantage of the most-productive part of your pedal rotation (while lessening time spent in the least-productive part).
To upgrade from round rings, we recommend choosing Q rings with the same tooth count. For example, if you currently ride a 52t noQ , then we recommend a 52t Q ring.
