I hope so: I've built someone a TT bike without a NW chainring or a clutched mech...
The advice I got was that if you weren't using a wide-range cassette, chain slap was unlikely and so therefore was the risk of unshipping your chain.
The chainring does have full height teeth and no ramps or pins; the cassette is 12-25.
A clutched rear mech seems the most effective precaution to me, as it addresses the problem (chain slap) rather than the symptoms.
1x10 without a wide narrow chainring - does it work?
I've got a clutched rear mech and this bike is ridden on road, albeit through potholes and hopping off kerbs.
