ROAD oval Chainrings


Why choose Premium absoluteBLACK Oval chainrings

Our studies led by University of Primorska, Slovenia show on the below video significant differences when using 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 that means? In short, 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 themore effort you have to put in, therefore it's important to maximize efficiency and effectiveness and you can improve both of them by using oval chainrings.

Why our oval chainrings 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 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 AbsoluteBlack oval chainrings matters

Absolute Black oval road chainrings deliver power more smoothly to your rear wheel. This means you are better able to generate and maintain, constant cadence. Because oval chainrings reduce the peak loads on knee joints, riders using them get less stress on the joints (knees) and therefore are able to keep certain level of effort for longer. This results in higher average speed. The compound effect of switching to oval chainrings; the relaxed legs, added climbing ability and reduction of cramp means your overall enjoyment of the ride is enhanced.



Why our Oval chainrings do not have adjustable timing

At Absolute Black we have extensively studied the relevant performance data regarding the optimum percentage of ovality, shape and, critically, the timing of the oval – the positioning of the high and low points of the oval, in relation to the position of the crank arm and focus this into one single mounting position – this is the really important part of what makes Absolute Black Oval chainrings so effective. By simplifying our oval chainring design, to reflect a single high performance ‘sweet-spot’, we are able to make the process of fitting Absolute Black oval chainrings faster and easier, as well as making our rings even lighter.


WE HAVE PROVEN OVAL


Absoluteblack believe that using oval chainrings bring significant efficiency advantages to cyclists. Oval chainrings do not produce more power, they allow you to unleash your true potential. They achieve this by optimising the pedalling torque you generate, reducing your effort on the climbs and increasing your speed at the same time - so you can be faster and more efficient. Naturally, we’re obsessed with making the finest oval chainrings in the world. We do this by spending countless hours refining the design and detail of each product. Then we use the best possible materials and high-tech, state-of-the-art CNC milling machines to produce oval chainring perfection. All Absoluteblack chainrings are compatible with 10 and 11 speed drivetrains.
