Description of absoluteBLACK Chainring - Direct Mount - Narrow Wide - Oval for Shimano XT FC-M8000 12-speed - black

The Original one and only absoluteBLACK Premium, Shimano XT 12-speed compatible 1X Oval traction chainrings are designed for Shimano XT M8000 and MT700 cranks only. They feature exactly the same excellent oval shape as rest of absolutBLACK's oval chainring portfolio. This new type of direct mount chainring will make your Shimano crank looking great. This particular chainring will ONLY work with CN-M8100 12-speed chain due to different thickness of the teeth.

Oval (elliptical) chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.

Always use a new chain with a new chainring.
If you wish to check for frame clearance with new oval ring, below you can find measurement of biggest dimension of the oval (tip to tip of tooth): 28T: 127mm ; 30T: 134mm ; 32T: 143mm ; 34T: 151mm
Chain options: 10, 11 or 12spd chain for geared bike or 6-9 spd one for SS (1/8" also fits).

Advantages of the special oval chainings for SHIMANO XT 12-speed:

  • absolutBLACK mastered their oval chainrings to perfection, so you can get best possible advantage from the oval/elliptical shape.
  • Finest design to provide excellent weight to strength ratio.
  • One of a kind special oval shape (Patent Pending).
  • Greatly improves traction and climbing abilities
  • Unique Patent Pending narrow-wide teeth profiles to keep your chain in place for minimum 12 months!
  • Special 3D teeth machining for ultimate mud relief decrease wear and noise dramatically
  • All rings have built in threads for easy of mounting and reduction in weight.
  • Superb quality and great look.
  • You will ride faster using ovals. If you keep using round ring then others will get quicker.
  • You will not "feel" the oval shape at all
  • Reduces stress on knees



How to mount Absoluteblack oval chainring:
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.

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.
