Oval chainrings featuring subtle but efficient 10% ovality where the smallest diameter is at the weakest point of the pedal stroke and the maximum diameter at the strongest point of the pedal stroke. Q-Rings offer 5, sometimes 4 or 3, Optimum Chainring Positions (OCP) that can be adjusted to take advantage of the pedals stroke's most productive zone.


Q-Rings are ideal for riders trying these rings for the first time and getting the correct setup can take a short period of time. Would advise newbie users of Rotor Q-Rings to take careful note of setup and also NOT to try the QXL chainrings as these are designed for specific riders and riders with lots of experience in using Q-Rings.


  • Q-Rings offer 10% ovality, not 16% as the QXL chainrings
  • Q-Rings ensure exceptional drivetrain stability
  • Q-Rings can increase an avid cyclist’s performance by as much as 4 seconds per km in a sprint – that’s twice the benefit of an aero wheelset
  • Inner ring only fitting 110 and 130 BCD cranks (5 spider)
  • 5 Optimal Chainring Position (OCP) points (4 on 50/34)
  • Reinforced rigidity and aerodynamic
  • Designed to work with all 9, 10 and 11 speed groupsets
  • Some cranks require specific Q-Rings


  • Colours: Black or red
  • BCD options: 110 or 130, spider x 5
  • Material: 7075-T6 aluminium alloy, 100% CNC-machined
  • Shifting pins: steel
