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.

The importance of timing and shape with oval chainrings


The oval chainring movement across all cycling disciplines is growing rapidly, led by absoluteBLACK, the world leaders in this important product category.

However, not all oval chainrings share the same performance characteristics as absoluteBLACK. The 'clocking' (timing) and shape of the oval are the most crucial parts of any oval chainring design, absoluteBLACK spent three years in design development and have perfected both timing and shape design elements - ensuring the ride quality of absoluteBLACK oval ring will be different and superior to ovals from other brands (as many abosluteBLACK customers already realised).

Where most other brands retain the same timing (position of the crank arm relative to the oval) and shape of the oval across all their sizes - because it's cheaper and less time consuming. absoluteBLACK believe that each different size ring requires a bespoke, optimised, perfect pedalling solution. So that is what we do - for every chainring absoluteBLACK make. For example, the smaller the chainring size, the bigger the ovality has to be to help climb steeper hills more effectively. We keep our exact Patent Pending data a secret, to ensure we get the best possible absoluteBLACK advantage over other brands, and you get the best possible ride experience.

Our longterm belief in oval and development of our design, has led absoluteBLACK to become the most commercially successful oval chainring product in the world. So keep in mind that not every oval chainring is equal to an absoluteBLACK.
