AbsoluteBlack Oval Chainring
Oval chainrings work because a rider does not produce power evenly through a pedal stroke. The oval chainring maximises the part of the stroke where power is produced and minimises resistance where it isn't. Oval rings make the spin cycle a lot 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.
These AbsoluteBlack Premium Shimano 110/4(bolt pattern) oval chainrings are designed for new Shimano cranks like Dura-Ace 9000, Ultegra 6800, Shimano 5800 and others. This is a shift-able chainring for 2X cranks.
