Boosted efficiency.

Round chainrings aren't going away anytime soon, but ovalized rings are becoming a much more common sight within the peloton. Carrying claims of reduced dead spots and increased pedaling efficiency, Rotor's Shimano Outer Aero Q-Ring is the ideal upgrade for any cyclist searching willing to stray from tradition in search of a few extra elusive watts. This chainring attaches to your current four-bolt Shimano crankset and offers three positioning options to let you truly dial in your pedal stroke.

Please note that this generation of Q-Ring isn't compatible with Dura-Ace 9100 or Ultegra R8000 cranksets.

  • Pedal more efficiently with this ovalized chainring
  • Aluminum construction balances weight and power transfer
  • Continuous surface leaves few edges for wind to catch on
  • Not compatible with Dura-Ace 9100 or Ultegra R8000 cranksets
