The ultimate solution for Cyclocross.  Its specially designed wide-narrow tooth profile keeps the chain really snug, allowing you to leave your chainkeeper in the garage. It saves more than 100g on average by removing the chainkeeper and the bashring from your existing 1x setup, or more than 200g if using 2x drivetrain. Works with Clutch type and non-clutch rear derailleur.


Please note, the chainring is optimized for running in the mud, having specially designed chamfers. But in the event of buildup of really heavy/sticky mud on the chainring, there is a small possibility of dropping the chain. KMC chains friendly. Always use a new chain with a new chainring. Suitable for Singlespeed conversions.

Chainguide needed?

No, but chainlength is important as you don't run clutch type rear mech. Short cage really recommended.


MSRP: from £58,99 only......


Important information for SHIMANO derailleur users.

In order to get best results we recommend increasing cage return spring tension. New derailleurs are assembled with the spring in the mount that allows the most relaxed position of the spring. However there is another position on the cage which will increase that tension.  It is a standard procedure, please navigate to point no.7 in the link. You may also ask your LBS to do it for you.

Sram users are not required to do that as oem springs are already in high tension position.


KMC chains: As some of you know we didn't recommend KMC chains in the past from few "dimension discrepancy" issues. We are very pleased to announce, that together with KMC we found a solution and KMC chains are now updated to work perfectly well with Absoluteblack chainrings. From now on KMC chains are recommended by us and updated version is already on the market. In fact KMC chains now perform much better than others with our rings, after this update!

Always use correct chain length

*Bypassing the rear derailleur, run the chain around front chainring/largest cog combination.

*Add 2 segments of the chain to this length for proper chain length.
