Rotor Round Outer Compact Chainring

If you want a Rotor ring because of the high quality machining and anodization but are not fond of the ovalized profile, this chainring if for you. It has the same features and finish of the Q-Rings except it is completely round. Profiled teeth aid shifting and durable finish adds longevity. Works with all 10-speed drivetrains and mounts to most 110mm BCD cranksets. Best when paired with a Rotor inner chainring.


  • Black anodized
  • 110mm BCD
  • works with 10 speed drivetrains
  • Multiple drillings for weight savings
  • From $115.00

    When my 2009 R3 cracked and was replaced with a 2012 R3, I switched from a compact SRAM Red crank to a compact Rotor 3D crank with these round chainrings on them. Front shifting performance was noticeably worse that it had been with the pre-2012 SRAM Red crank. I swapped these Rotor rings out for a new set of pre-2012 SRAM Red chainrings and shifting is significantly better. I like the Rotor 3D crank, but was not happy with these chainrings at all due to poor shifting.

    Cons Poor front shifting
