It's a Direct Mount chainring, so please use the original lockring to mount it on the crank. Always use a new chain with a new chainring

How to Mount Absoluteblack Oval Chainring to Shimano 12SPD Hyperglide+ Crank:

Using Hollowtech II BB Removal Tool (like BBB BTL-116 ), carefully open the lockring that holds the chainring on the crank(normal threads). Once the lockring is removed, remove the old chainring, and re-grease the splines on the crank. Place new oval chainring with convex side to the crank. The chainring/crank has special splines that only fit one way. Close the lockring to 35-50Nm of force. The chainring is only compatible with CN-M9100, M8100, M7100 & M6100 Shimano 12spd Hyperglide+ chains. Using other chains may cause the chain to drop very quickly from the chainring due to thinner than usual teeth.

It is ideal for 1x 12spd. The Oval (elliptical) chainring does not compromise the work of the clutch mechanism in the rear derailleur(video at the bottom). It also does not require a chain tensioner when used in single-speed applications. Riding out of the saddle, the uphill will become more pleasant.

The chainring's ovality is 10-14% (dependent on size) 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.

• Chain options: 12spd xtr9100, 8100, 7100 & 6100 Shimano 12spd Hyperglide+ chain only
• Chainguide needed? No. But if you want one, the chain guide should have two teeth more capacity than the nominal oval ring size.
