Rotor Shimano Outer Aero Q Ring

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.
