• One of a kind special oval shape that helps you climb easier and faster (Patent Pending)
• Over 15% stiffer than Rotor Qrings due to thicker, 5mm construction
• Bespoke AbsoluteBlack 6 point ramp and recess shifting design shifts better than any other brand and model of oval chainring
• You will not "feel" the oval shape while pedaling
• Your pedaling action will feel smoother
• Helps reduce stress on knees and helping your legs remain fresher for longer
• You will be able to maintain better cadence while climbing
• Reduces possibility of leg cramps
• You will reduce chainring/cog shifts by at least 15%

Installation steps

• First, you need to remove your crank from your bike. Once removed, unscrew 5 bolts that hold two chainrings together. Remove both original rings.
• If you have a removable spider on the crank - remove the spider by unscrewing 3x T25 torx bolts before mounting new chainrings. Locate new oval inner chainring with the small hole "timing indicator" positioned behind the crank arm. The bolt holes on the small chainring are recessed – so the nut heads will sit flush with the surface of the chainring - these recesses should face you when mounting the bolts.
• Absolute Black outer chainring has a specific hole indicator - position the outer ring to line up that hole with the crank arm. Reuse 4 original bolts that came with the crank and use our (provided) bolt for the hidden bolt hole when mounting both inner and outer oval rings (If you have carbon crank with integrated spider, reuse all 5 original bolts). If you are only switching the inner chainring to oval - use all original bolts that came with your crank.
• Tighten all 5 bolts with force of about 5-7Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur upwards by 2-3mm.

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.
