Why Absolute Black oval chainrings work
Absolute Black 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 Absolute Black 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. You don’t need to take our word at Absolute Black; 11 scientific studies by leading universities around the globe show that; in comparison to round chainrings, when using oval chainrings, human legs utilize more muscle groups - but each of them to lesser degree. The overall Load from pedalling an oval chainring is spread over greater muscle mass. 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. 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.
Word on BIOPACE
Please understand Absolute Black’s oval design IS NOT ‘Biopace’ technology. Shimano created their non-round Biopace chainrings with a completely different orientation of the biggest radius of the oval. Their ring orientation has since been widely accepted as being fundamentally wrong. Instead of positioning it in power zone - which is slightly below the level of the crank - they clocked it to the dead zone where human physiology generates least power. The result was that in power zone pedalling was too easy and in dead zone too hard, causing knee pain and lumpy pedalling cadence. Exactly opposite to how it should be. The opposite of how it is with an Absolute Black oval chainring fitted to your bike
Bonjour, j'ai actuellement Giant Defy Advanced Pro 1 de 2015 monté en Ultegra 6800 (50/34 - 11/32). Est-ce que je peux remplacer les plateaux 50 et 34 par des plateaux ABSOLUTE BLACK PLATEAU OVALE SUB COMPACT PREMIUM - 4 TROUS 110 MM en 46 et 30 ? Cela posera t il un problème au niveau du dérailleur ?
Bonjour
Ces plateaux fonctionnent sans aucun souci avec un pédalier Ultegra 6800. Il faut juste bien respecter le couplage 30/46 ou 32/48 dents et refaire un réglage de dérailleur avant comme indiqué dans la vidéo suivante

le plateau de 46 est il décliné en plusieurs couleurs sinon de quelle couleur disposez vous merci pour la réponse la visserie est elle classique et similaire à celles montées ?
Bonjour,
Le plateau de 46 dents existe en couleur gris :

Il existe aussi en couleur noir :

En en couleur champagne, pour le moment pas disponible
Le plateau 46 dents ne doit être installé qu'avec un plateau Absolute Black en 30 dents qui est livré avec la visserie nécessaire pour l'installation des deux plateaux
