ROTOR 110×4 Chainring

The ROTOR 110×4 Chainrings are machine CNC’d from ultralight aeronautic-grade 7055 aluminum. The result is great looking, stiff chainrings that feature clean shifting.

The chainrings are 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. It is compatible with 9-, 10-, 11-, 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.



The ROTOR 110×4 Chainring is available in the following chainring sizes:

  • Size: 52/36 | 53/39 | 52 | 53 | 36 | 39
  • Shape: Round | Q-Ring

The ROTOR 110×4 Spider is required for use with the 2INpower, INpower, ALDHU or VEGAST cranksets (not required for use with the ROTOR INspider or with Shimano cranksets).
