*Reduces stress on knees
There is a small mark (triangle shaped) on the inner circumference of the chainring.
This mark Must sit behind the crank arm. Mounting procedure is identical for SLX and XT cranks. Use the stock 1X Shimano M8 chainring bolts that come with crank and Torque them to about 7Nm. IMPORTANT – if you are converting from 2X chainring setup to 1X and wish to mount 30T absoluteBLACK ring you need to purchase 1X bolts from Shimano for this crank because 2X bolts are too short. Other chainring sizes can use Shimano 2X bolts.
It is ideal for 1x 10/11/12 and Singlespeeds. Oval (elliptical) chainring does not compromise the work of the clutch mechanism in rear derailleur(video at the bottom). It also does not require a chain tensioner when using in the single-speed application. Riding out of the saddle on the uphill will become more pleasant.

Chainguide needed? | No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size. |
