How to mount AB Oval chainring to Easton Cinch crank:

CINCH is a system used by Easton and RaceFace to secure a chainring on the crank. Hence same way of mounting apply. AB chainring has a mark on the backside that you need to line up with the center of the crank arm to achieve the correct position. Once this is done use BB key to close the lockring (torque spec written on the lockring itself)

It is ideal for 1x 9/10/11/12 system and Singlespeeds!. Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur. It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting.


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 for SS. If used in 1x9 drivetrain - 10spd chain must be used to obtain the performance. (yes - 10spd chain will work great on 9spd cassette)

Chainguide needed?

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