ROTOR 110×4 Aero 1x Chainring

The ROTOR 110×4 Aero 1x Chainring is stiff, lightweight and aerodynamic. For peak aerodynamics and aesthetics, we recommend using these rings with the ROTOR Aero Crown.

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. 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 chainring is available in the following chainring sizes:

  • Size: 40 | 42 | 44 | 46 | 48 | 50 | 52 | 54
  • Shape: Round | Q-Ring

The ROTOR ALDHU Direct Mount 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).


  • Crankset: With ALDHU Spider: Compatible with ROTOR’s 2INpower and INpower DM power meters as well as ALDHU and VEGAST cranksets
  • Crankset: Without ALDHU Spider: Compatible with most 110x4 cranks (does not fit Shimano R8100/9200 cranksets)
  • Chain: Compatible with 9-, 10-, 11-speed groupsets. Also works with 12-speed Shimano and 13-speed ROTOR groupsets.
  • Not compatible with SRAM AXS 12-speed groups
  • Not compatible with Stages drive side power meters


  • Color: Black anodized
  • BCD: 110x4 asymmetric
  • 100% CNC-machined, 7075 aluminum alloy
  • OCP Mount technology: Fine adjustment for OCP positions
