Race Face Narrow Wide Chainring - Review - Pinkbike

First Look: Shimano's New Deore XT Group - Pinkbike
Shimano uses their own "DYNAMIC CHAIN ENGAGEMENT" on their chainrings that does the same thing differently.

anyway the Narrow wide chainring works pretty well by itself but but coupled with a clutched rear derailleur and you will almost never drop a chain. I'm running one on my rigid setup 1x9 with a non-clutch RD so on rare occasions I still drop a chain. Had one my last time out actually on it. The raceface ones are cheap $30 on amazon so worth a shot.
