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.
- Pedal more efficiently with this ovalized chainring
- Aluminum construction balances low weight and stiff power transfer
- Continuous surface leaves few edges for wind to catch on
