I have a 44/28 setup on my Hillborne with a Shimano 105 (FD-5700) front derailleur. I can't set it at the recommended height (1-3mm clearance above large chainring) due to the rear of the cage hitting the chainstay. It shifts fine without dropping the chain off the large chainring. In fact, I watched a Park Tool video on proper set up of a front derailleur and they state that if the gap between the ft derailleur and large chainring is more than recommended it can cause the chain to be dropped outboard. Interesting, when I set up my Disc Trucker with a 42/28 and CX70 front derailleur, I was able to set the hight as recommended and it caused problems with the chan being dropped outboard. When I raised the derailleur to create a larger gap to the chainring, it shift perfectly.
