In addition to a lighter, stiffer chainring, there was one more important factor when designing Qarbon Q rings: compatibility. No need to swap out your Shimano cranks to accommodate our Qarbon Q rings, ROTOR has crafted Q rings Qarbon Shimano 110x4 just for you. Choose from 3 Optimum Chainring Positions (OCP) to fine-tune your improved riding experience and go farther and faster with less fatigue.
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.
