2x front derailleur shifting adjustment for BB92 shell
I don't have enough 'reputation' to add a comment, but +1 on 'mikes' comment about the derailleur being too high. If the derailleur is a bolt-on (hard to tell from pix), maybe the bike was designed for a larger big chainring? 

Also, if the limit screws are all the all the way out, you might have to pre-load the derailleur travel a bit before tightening down the cable clamp.
