I am experiencing chain drop under certain situation and hope to find out if something is not adjusted correctly with the FD or that I am doing it wrong.

The symptom: Chain get thrown outside of the big ring.

Situation: Always when I try to accelerate. I am usually in the small ring (50/34) and I want to up-shift so I will move the RD to either the 3rd or 4th cog. Then I am still spinning and want to move to the bing ring. At which time the chain is thrown outside of the big ring.

I measured the gap between the the FD and the big ring when they are aligned and it fits one penny so I think I am okay with the spacing. Could it be the FD limit adjustment?

If I do the same thing but shift the front with a smoother spin (not trying to accelerate then it shifts fine.)

Thanks in advance for any suggestions.
