Any tips on this? It happens when I'm shifting from the little to big ring on the front derailleur. The chain comes off (over the front ring) or has trouble finding the front ring. I had 2 bike shops adjust the limit screws and changed the chain. This is much more likely to happen when I'm in the middle of the cassette on the back (front derailleur shifting much smoother when chain is on the easiest first or second gear in the back-harsher from the third, and worse from there).

I'm running shimano 105 10 speed (2014 version).

Thanks!
