Advantages of absoluteBLACK oval chainrings:

  • Have you ever had to walk the climb on sportive race? These rings will save you from it.
  • Your pedaling will feel smoother.
  • AB oval reduces stress on knees and helps your legs remain fresher for longer.
  • You will be able to maintain better cadence while climbing.
  • Reduces possibility of leg cramps.

Why absoluteBLACK's oval chainrings work:

Oval chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape 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. 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 pedaling 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 pedaling 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.

How to mount 110/5 Oval chainrings:

First you need to remove crank from the bike. Once removed, unscrew 4 bolts that hold two original rings together with T-30 torx key. Take off both original rings. Position Absoluteblack oval chainring in place where the big chainring was. Please note that small indicator on the chainring must sit behind crank arm - same way as original chainring indicates its position. Use provided AB bolts to lock the chainring in place using T-30 torx key with force of about 5-7Nm. Mount your crank back to the bike. Done

Mir persönlich dürfte es ja gern noch ovaler sein. Davon ab, sind es (wenn nicht) die leichtesten N/W, im Vergleich recht günstigen, dafür ziemlich robuste und steife Kettenblätter, die zuverlässig ihren Job machen. Seitdem ich sie drauf habe, ist mir die Kette bei 1x11fach noch nicht einmal abgesprungen - was bei dem Vorgänger einer namhaften Marke regelmäßig der Fall war.
