absoluteBLACK Oval Road 110BCD 4B 50T 2x Outer Traction Chainring Black

Oval chainrings work because a rider does not produce power evenly through a pedal stroke. Something cyclists minimize through working on pedalling technique. Oval rings negate the need for the precision in this technique as they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.
