ROTOR 107×4 Oval Chainrings for SRAM AXS

The ROTOR 107×4 Oval Chainrings for SRAM AXS bring the benefits of oval rings to your SRAM AXS crankset! Featuring a 107 BCD 4-bolt configuration, these ROTOR rings are 100% CNC-machined from 7075 aluminum alloy for high strength and low weight.



The chainring is available in the following chainring sizes:

  • 48/35
  • 50/37


The ROTOR 107x4 SRAM AXS Chainrings are compatible with SRAM Red, Force and Rival cranksets that use a 107 BCD, 4-bolt spider. This includes the SRAM RED/Force AXS 107 BCD Power Meter.

Note 1 - Installation on an AXS crankset requires new chainring bolts (sold separately on this page).

Note 2 - Some frames may run into front derailleur clearance issues with the larger diameter 50T ring. If you are currently running a 48T ring, please make sure you have room to raise your front derailleur in order to accommodate the 50T.
