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. In addition, the oval shape works to smooth your pedal stroke and increase both traction and power.

The chainring is available in 48/35 and 50/37 chainring sizes.


  • Crankset: The ROTOR 107x4 SRAM AXS Chainrings are compatible with 12-speed 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.
