Chain dropping inside when shifting to big ring
I've recently upgraded my groupset to Di2 Ultegra. New chain and cassette included.
I've dropped the chain a couple of times now when shifting from the small ring to the big ring, but the chain is dropping between small ring and the frame. It seems that the chain moves up to the big ring, doesn't quite catch and then falls back to the small ring and past it until it's dropped.
It happens under relative light load. Not had any issues shifting from big ring to the small ring.
Any ideas on what causes this and how to fix it?

sounds like either the front mech hasnt been setup or not setup correctly

You need to adjust the high limiting screw to allow the mech to move out more.

Ok, thanks chaps, will try adjusting it. I was thinking if that was the case it'd keep partially catching and not quite making it, rather than completely slipping off in the opposite direction to where I'm trying to shit.0

Check your derailleur azimuth and vertical alignment. If they are not correct then it will make it very hard to achieve reliable shifting performance.- - - - - - - - - -
