Oval chainrings work so well because a rider does not consistently generate power during a kick. Their shape optimizes the transmission of power from the pedals to the rear wheel. Oval chainrings give the pedal kick more uniformity and make climbs easier. Hard to believe - a round chainring does not transmit the torque as evenly on the rear wheel as an oval creates! The rider will find pedaling with an oval chainring much "rounder" than with a true round.
