Why absoluteBLACK oval chainrings work
Oval rings work with the natural human physiology. Oval chainrings maximise the part of the stroke where power is produced and minimise resistance where it isn't. As a direct consequence, oval rings enhance a cyclist's ability to spin with a smoother power delivery and feel easier on legs while climbing.
You will actually feel your pedal stroke to be more " round" with an oval chainring than with a round chainring.

Why using oval chainrings matters
In comparison to round chainrings, when using oval chainrings, human legs utilise more muscle groups - but each of them to lesser degree. The overall load from pedalling an oval chainring is spread over a greater muscle mass, which reduces the peak loads on knee joints.
This has three key benefits: firstly, it gives you the feeling of fresher and more relaxed legs. Secondly, it allows you to achieve higher average speed riding uphill. Thirdly, spreading the pedalling load over more muscles reduces the risk of cramp, even when riding hard. This means your overall enjoyment of the ride is enhanced. On MTB side in addition rear tyre traction improves greatly on loose and slippery terrain when using oval. Climbing becomes much easier in demanding terrain.
