• Absolute Black


British design at its best. absoluteBLACK is the largest manufacturer of oval chainrings in the World. We are devoted to extraordinary design, European manufacturing and production of parts that perform great & are made to last.

We believe anything out there can be made better, including chainrings. We made it our goal to improve riders pedaling efficiency by changing the way how torque from the crank is delivered to rear wheel. This is how absoluteBLACK oval chainrings found its way to general market and gained Worldwide recognition.


We are passionate about every step of the production cycle. It starts from material sourcing where we only pick the very best aluminium alloy we can find for our chainrings. Such selection makes our products stronger and more durable from the very beginning. We use cutting-edge 3D CAD software that give us the freedom to create beautiful yet remarkably rugged parts that are made to last.

Our attention to detail is showing in every single path of CNC tools that carve the final product. Cooperation with the best anodizing plant in Europe deliver us not only excellent anodizing finish, but they also care about environment. It’s important to us.

We are in full control of every single step from designing through production to final product. Even our packaging and labels are designed by us and made by local producer.

We continually refine all of our parts until we’re satisfied that they are at its best – and we provide them to you at a competitive price.


The company’s foundation comes from our passion to cycling. absoluteBLACK is still a family-owned brand.

Our design office is based in London, England. All metal components are manufactured and dispatched from Poland (EU) using German aluminium, then skillfully anodized in the United Kingdom. Because of our attention to every detail, we’re proud to produce bicycle parts with an unbeatable combination of styling, performance, and precision.


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.


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.


Our studies led by the University of Primorska, Slovenia show on the below video significant differences when using absoluteBLACK Oval chainrings compared to round. Up to 9% increase of Force 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. What does that mean? In short, it means that you will consume less energy at the same power output using Oval chainrings so you can ride for longer and/or faster. Our data show that the higher you climb the more effort you have to put in, therefore it’s important to maximize efficiency and effectiveness and you can improve both by using oval chainrings.
