absoluteBLACK specialise in manufacturing of performance enhancing bicycle components that change the way you ride.

The only scientifically proven oval chainrings on the market. Studies led by the University of Primorska, Slovenia show significant differences when using absoluteBLACK Oval chainrings compared to round. Up to 9% increase of pedaling effectiveness, up to 7% less oxygen consumption, up to 15% less Ventilation (breathing) and up to 10% heart rate decrease when using oval chainrings versus round.

Climb easier, pedal smoother and get less tired.

Oval chainrings don’t produce more power, they increase your pedalling effectiveness. This means they reduce the component of your pedal pushing force, which doesn’t contribute to moving your bike forward. The less force you waste the more energy you preserve, allowing you to push harder when it counts or simply reduce tiredness. This is the reason why you can ride faster with our ovals.

Why our oval chanrings work.

Our premium Oval chainrings work because riders do not produce power evenly through a pedal stroke –the musculature of human legs makes it difficult to maintain an even power delivery to a round chainring. Believe it or not, but a round chainring doesn’t transfer torque to your rear wheel as smoothly as an Oval one. Oval rings work with the natural human physiology. Oval chainrings maximize the part of the stroke where power is produced and minimize 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 much easier on legs while climbing. Meaning you will go faster and get less tired. You will actually feel your pedal stroke to be more “round” with an Oval chainring than with a round chainring.
