ROTOR 110×4 1x Chainring

The ROTOR 110×4 1x Chainring is stiff and lightweight. This chainring is available in both round and oval and comes in a variety of chainring sizes, making it extremely versatile.

This chainring is compatible with most Shimano road cranksets (please see Compatibility tab for details) as well as with ROTOR modular cranks and power meters. This includes the 2INpower, INpower, INspider, ALHDU, and VEGAST cranksets. Using ROTOR’s Universal Tooth Profile, these chainrings are compatible with 9, 10, 11, and 12-speed groupsets. This includes ROTOR 12 and 13-speed groupsets.

The direct mount spider, required for use with ROTOR cranks, features a spline interface that mounts directly to the axle. The spider also includes refined OCP Mount technology so you can adjust your chainring position in one-degree increments.
