Oval chainring - more dropped chains?

I switched to an oval ring again and have found that I seem to drop my chain more often than before (it dislodges from the bottom). Has anyone else had the same experience?

New chain, one-up chainguide, GX 12-sp drive. Makes me wonder if my clutch is starting to go. I've only noticed it on long-sustained downhills (WBP) and not locally on the Shore.

I'm curious if anyone has thoughts.

Top Guide?

yep, that's the one-up guide I have - and yes it is adjusted correctly.

So it is not a full drop, just bottom up to the guide. I take a pedal and it flips back...

I used oval rings for years and didn't notice any more dropped chains than before or since. I did not use any chain guide at all. Just NW rings and clutch derailleurs.

From personal experience, it’s your clutch. 

Also shortened a chain once and seemed to cure the problem.

I’ve found the chain will come off the bottom when I back pedal to drop the pedal down on the right side. My left foot is forward normally when cranks are level. So if I hit a bump at the wrong time the chain can come off.  More so when the chain and ring are worn. And clutch loose.

Running Shimano XT, between Narrow wide absolute Black chainring and the clutch der the chain almost never comes off IME, maybe once a season

Thanks for the feedback - I'll shorten the chain a couple of links first before replacing the derailleur - as it seems you can't adjust a Eagle clutch.

I have forgotten to turn the clutch lever ON .Lots of times never dropped a chain either. OneUp oval , OneUp guide, XT rear derailleur , XT chain
