The Feature of Oval Chainring
1. The ellipse is suitable for TT competitions.
2. If your limit is 150KM and you are participating in a 100KM race, using the elliptical disk can bring you a 7% speed increase, which is a speed increase in exchange for draining your physical energy in advance.
3. It is easier to increase the cadence on flat roads.
4. The dead center interval is easier when going uphill.
