I've found that unless you're doing big shreddz, a NW ring has much more of an impact on chain retention than a clutched mech, and generally a 1x drivetrain happily runs with just the NW ring.
Same. Currently have a NW with 10-speed 105 and 9-speed X0 and neither throw their chains. I used to ride a single chainring on the road BITD with 5-6 speed and it used to come off quite regularly when cross-chaining.
Thanks — that's what I figured too
