What size should I choose?

* 30T Oval chainring has an ovality of 28/32T and is best for someone who uses currently 28 or 30T round ring.

* 32T oval ring will suit best someone who uses 31 or 32T chainring currently. While pedaling, you will feel quite similar effort to the one riding round 31T ring ( the smallest diameter of the oval is 30T), but you will gain the speed similar to riding 33/34T chainring.

* 34T Oval chainring has an ovality of 32/36T and is best for someone who uses currently 33 or 34T round ring.

How to mount Absoluteblack oval chainring:

There is a small mark (triangle shaped) on the inner circumference of the chainring.

This mark Must sit behind the crank arm. Mounting procedure is identical for SLX and XT cranks. Use the stock 1X Shimano M8 chainring bolts that come with crank and Torque them to about 7Nm. IMPORTANT - if you are converting from 2X chainring setup to 1X and wish to mount 30T absoluteBLACK ring you need to purchase 1X bolts from Shimano for this crank, because 2X bolts are too short. Other chainring sizes can use Shimano 2X bolts.

It is ideal for 1x 10/11 and Singlespeeds. Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur(video at the bottom). It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant.

Ovality of the chainring is in range of 10.2-14.4%(size dependent) and feels perfectly round when riding. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market backed by tens of thousands of customers.

The most advanced, Patent Pending narrow/wide tooth profile currently produced, guarantee minimum 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.

Chain options

10, 11 or 12spd chain for geared bike or 6-8 spd one for SS (1/8" also fits).

Chainguide needed?

No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.

Designed in UK. Manufactured in Poland (EU).

The World's best oval (elliptical) narrow/wide Shimano 96bcd traction chainring.

If you wish to check for frame clearance with new oval ring, below you can find measurement of biggest dimension of the oval (tip to tip of tooth):

30T: 134mm ; 32T: 143mm ; 34T: 151mm

Word on BIOPACE - Please understand that this is not Biopace technology. Shimano created Biopace with the completely wrong orientation of the biggest radius of the oval. 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 generates least power. The result was that in power zone pedaling was too easy and in dead zone very difficult. Exactly opposite to how it should be.

The importance of timing and shape with oval chainrings


The oval chainring movement across all cycling disciplines is growing rapidly, led by absoluteBLACK, the world leaders in this important product category.

However, not all oval chainrings share the same performance characteristics as absoluteBLACK. The 'clocking' (timing) and shape of the oval are the most crucial parts of any oval chainring design, absoluteBLACK spent three years in design development and have perfected both timing and shape design elements - ensuring the ride quality of absoluteBLACK oval ring will be different and superior to ovals from other brands (as many abosluteBLACK customers already realised).

Where most other brands retain the same timing (position of the crank arm relative to the oval) and shape of the oval across all their sizes - because it's cheaper and less time consuming. absoluteBLACK believe that each different size ring requires a bespoke, optimised, perfect pedalling solution. So that is what we do - for every chainring absoluteBLACK make. For example, the smaller the chainring size, the bigger the ovality has to be to help climb steeper hills more effectively. We keep our exact Patent Pending data a secret, to ensure we get the best possible absoluteBLACK advantage over other brands, and you get the best possible ride experience.

Our longterm belief in oval and development of our design, has led absoluteBLACK to become the most commercially successful oval chainring product in the world. So keep in mind that not every oval chainring is equal to an absoluteBLACK.
