Sram Compatible absoluteBLACK Premium Sram compatible Oval chainrings (110/5bcd) are designed specifically for Sram cranks that have 1 hidden chainring bolt behind the crank arm like Sram Red, Red eTap, Red22, Force1, Force22, Rival, Rival1 and more. These are finest shift-able oval chainrings on the market.
Why Oval Rings 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.
Fresher and More Relaxed Legs With oval rings, rear tyre traction improves greatly on loose and slippery terrain. Smoother power delivery to your rear wheel means that you will be able to maintain better, constant cadence; get less stress on the joints and be able to keep certain level of effort for longer. This results in higher average speed. According to absoluteBLACK 11 studies made by various Universities in the World show that using oval chainrings human legs utilize more muscle groups (compared to round one), but each of them to lesser degree. Load from pedalling an oval chainring is spread over greater muscle mass which in effect gives you the feeling of fresher and more relaxed legs.
