ROTOR Oval Chainrings for Shimano GRX

The ROTOR Oval Chainrings for Shimano GRX bring the benefits of oval rings to your GRX crankset! Featuring a 110 BCD outer and 80 BCD inner 4-bolt configuration, these ROTOR rings are designed specifically for Shimano GRX cranks. They are 100% CNC-machined, 7075 aluminum alloy for high strength and low weight. In addition, the oval shape works to smooth your pedal stroke and increase both traction and power.



The chainring is available in the following chainring sizes:

  • 46/30
  • 48/31

Please note, we recommend using these chainrings only in the combinations listed above. For example, a 48/30 or 46/31 set-up would void your warranty, could result in poor shifting and performance and dropped chains.


These ROTOR chainrings are designed for Shimano GRX RX810 and RX600 2x cranksets.


  • Color: Black anodized
  • BCD: 110x4 outer | 80x4 inner
  • Ovality: 12.5%
  • Chainline: 46.9 mm
  • Weight: 46/30 - 123 grams | 48/31 - 149.5 grams
  • 100% CNC-machined, 7075 aluminum alloy
