Why our oval chainrings work

Our Oval chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize 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.

Why it matters

Traction, Traction and Traction. With oval rings rear tire 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 (knees) and therefore be able to keep certain level of effort for longer. This results in higher average speed. Moreover, 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 pedaling an oval chainring is spread over greater muscle mass which in effect gives you the feeling of fresher and more relaxed legs. It is world's finest oval chainring backed by tens of thousands of customers.

Other elliptical chainrings on the market


Clocking (timing) and shape of the oval are the most crucial parts of the design. Ride quality of Absoluteblack Oval ring will be different to ovals from brand X or Y. 2 years of development of our ovals resulted in commercially most successful product of its kind. AbsoluteBlack is the First company who managed to successfully popularize ovals in mountainbike sport.

Other manufacturers offer one timing and ovality setting for all chainring sizes, but pedaling behavior changes with each size considerably. To optimize for this, every chainring size needs to be slightly different. For example the smaller the chainring size the bigger the ovality has to be to help climb steeper hills more effectively. This is where we specialize in and optimize every size to particular pedaling style. This is also why we do not provide exact figures about timing and ovality of the chainring as each one is special and we need to protect our Patent Pending solutions. Due to our Global popularity and success there are now more companies releasing "similar" products. But "similar" is not the same. Even very small change in parameters of the oval shape and timing gives entire different feeling and performance. We mastered our oval chainrings to perfection, so you can get best possible advantage from the oval/elliptical shape.
