Hey Garth, Really interesting points! I do need to look on the middle ring 'T clearance'. The frame I'm working with is the Saluki for this question though not the XO3. I've had 4 occurrences over 2 days of the chain coming off the 36T middle;
1. Came off entirely, onto the BB shell 2-3. 'downshifted' to the 24T ring 4. 'upshifted' to the 46T ring Honestly I don't remember alot of specifics but I was near the high or low rear cog in each of the instances and very often there was some kind of bump or sharp acceleration accompanying the issue. As for trimming the FD, its not a constant thing. Only when I move the rear chain line 3+ cog's usually... so not a terrible burden but definitely something I notice a couple times a ride. The lack of the FD has me shifting more boldly through 2-3 rear cogs at a time without having to think about adjusting my FD trim. This also might be something with the bar ends on drop bars, I'm not used to haveing to work both shifters simultaneously or near simultaneously in that handlebar setup whereas on the alba's or M-bars it was second nature.
