With ROTOR's Q-Rings oval chainrings, you ride further and faster with less fatigue because you use your power more efficiently. The Q-Rings vary the resistance when pedaling according to the natural strengths and weaknesses of your legs. Because the smaller diameter of the oval is aligned with the weakest point of your exertion and the larger with the strongest point, you make the most of the most productive part of your pedaling movement while reducing the time for the less productive part. As a result, your pedaling feels significantly "rounder" than with classic round chainrings.

The Direct Mount (EM) chainrings from Rotor are created in a one-piece design and are milled from the solid. The result is beautiful chainrings that can be integrated into existing Shimano and SRAM groupsets when mounted on a compatible crank. The chainrings of the Rotor MTB Direct Mount (DM) cranks R-Hawk, R-Raptor and Kapic as well as the two power meters INpower DM MTB and 2INpower DM MTB are identical and interchangeable.

Direct mount:
All current ROTOR cranks from the ALDHU and VEGAST road series, the RHAWK, RRAPTOR and KAPIC MTB series and the INpower DM and 2INpower DM power meters use the Direct Mount system, which has been established in the mountain bike sector for years, to mount the chainrings. This enables easy chainring changes, direct traction on the axle and maximum flexibility when choosing the gear ratios and drive characteristics. In addition, the fine gearing between the crank and the chainring enables oval ROTOR Q-Rings chainrings to be adjusted to an accuracy of 1°.

OCP "Optimal Chainring Position":
The optimal chainring position with oval chainrings is important. OCP stands for the various adjustment options that ROTOR Q-Rings offer to adapt to the specific pedaling characteristics of the rider. You can determine your OCP if you know your optimal chainring angle (OCA), which you can determine by performing a TORQUE 360 pedaling analysis with ROTOR POWER analysis software (requires optional ROTOR INpower or 2INpower power meter).
