The Original one and only absoluteBLACK Premium, Shimano 12 speed compatible Direct mount 1X Oval traction chainrings are designed for XTR M9100, XT M8100 & SLX M7100 cranks. They feature the exact same excellent oval shape as rest of our oval chainring portfolio. This new type of direct mount chainring will make your Shimano crank looking great and perfectly mesh with new Shimano 12spd chain. This particular chainring will ONLY work with CN-M9100, 8100 & 7100 chain due to different thickness of the teeth.
It’s a Direct Mount chainring so please use original lockring to mount it on the crank. Always use a new chain with a new chainring

How to mount Absoluteblack oval chainring for XTR M9100:
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, take off old chainring, re-grease the splines on the crank. Place new oval chainring with convex side to the crank. Chainring/crank has special splines that only fit one way. Close the lockring to 35-50Nm of force. Chainring is only compatible with XTR CN-M9100 chains. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth.
