Advantages of our Oval chainrings:
Our Oval chainrings maximize rider efficiency by leveraging your pedal stroke where your power is produced and reducing resistance where your power is least.
Oval rings allow you to climb easier and faster with less fatigue.
They offer a consistent power delivery that allows you to maintain an even cadence and a higher output level for longer periods of time.
Oval rings provide a smoother feel on your legs during climbing
Higher average speeds have also been achieved in various studies.
The power output attained during intermittent maximal sprints in one study was 2.4% - 6.7% greater with non-circular (Oval) chainrings.
