Estimated Shipping Widget will be displayed here! (with custom color)
The Original one and only absoluteBLACK Premium, Shimano 12spd Hyperglide+ compatible Direct mount 1X Oval traction chainrings are designed for XTR M9100, XT M8100, SLX M7100 & Deore M6100 cranks. They feature the exact same excellent oval shape as the rest of our oval chainring portfolio. This new type of direct mount chainring will make your Shimano crank looking great and perfectly mesh with the Shimano 12spd Hyperglide+ chain. This particular chainring will ONLY work with CN-M9100, 8100, 7100 & 6100 Shimano 12spd Hyperglide+ chain due to the different thickness of the teeth.
It is ideal for 1x 12spd. Oval (elliptical) chainring does not compromise the work of the clutch mechanism in the rear derailleur. It also does not require a chain tensioner when using in singlespeed application. Riding out of the saddle on the uphill will become more pleasant.
Ovality of the chainring is in the range of 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.

How to mount Absolute Black Oval Chainring to XTR M9100 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, take off the 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. The chainring is only compatible with XTR CN-M9100 chains. Using other chains may cause the chain to drop very easily from the chainring due to thinner than usual teeth.
