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.
