Oval chainrings don't produce more force, they increase pedalling efficiency through better transmission of forces. This means that you won't necessarily go further by pedalling harder. But the less force you lose, the more energy you keep, allowing you to pedal harder when you need to and thus reducing your general fatigue. That's why you can ride faster, longer and further with oval chainrings.

Studies conducted by the University of Primorska, Slovenia, show significant differences between the use of AbsoluteBlack Oval chainrings and conventional round chainrings. It is proven that using an oval chainring can provide up to a 9% increase in pedal stroke efficiency, up to 7% less oxygen consumption, 15% less breathing and up to a 10% decrease in heart rate.
