Absolute Black


Sorry, this item is out of stock


The Original, the one and only absoluteBLACK Premium (Shimano XTR M9100 compatible) Direct Mount 1X Oval Traction Chainrings are designed for Shimano XTR M9100 and M9120 Cranks Only. They feature exactly the same excellent oval shape as absoluteBLACK's other Premium Oval Chainrings.

This new type of direct mount chainring will make your Shimano crank looking great. This particular chainring will ONLY work with CN-M9100 chain due to different thickness of the teeth.

Premium Oval Ring is ideal for 1x 11 & 12 speed and Single-speeds. Oval (elliptical) Chainring does not compromise the work of clutch mechanism in rear derailleur, nor does it require a chain tensioner when using a single-speed application. 

Ovality of the chainring is in 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.

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, and place the new oval chainring, with convex side to the crank (Chainring/crank has special splines that will 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 easily from the chainring due to thinner than usual teeth.
