HOW TO MOUNT OVAL CHAINRING TO 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 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 CN-M9100, M8100, M7100 & M6100 Shimano 12spd Hyperglide+ chains. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth.
