ROTOR 110×4 Oval Aero Chainring

The ROTOR 110×4 Oval Aero Chainring gives you the benefits of stiff chainrings in a neat, clean-shifting, aerodynamic package. In addition, the oval shape works to smooth your pedal stroke and increase both traction and power. For peak aerodynamics and aesthetics, we recommend using these rings with the ROTOR Aero Crown.

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 chainring is available in the following chainring sizes:

  • Size: 50/34 | 52/36 | 53/39 | 54/39 | 50 | 52 | 53 | 54 | 34 | 36 | 39

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).

    Purchased a 53t and it was perfect fit on my r7000 105 crank. Used it to replace a 52t and shifts flawlessly with a 36 small chainring. Powermeter city always makes purchases super easy and the customer service is amazing! Will be back for future purchases.
