cel,

The trim function of your Shimano will work fine with the Campy front
derailleur. The compact specific front deraillure is not a marketing
gimmick. If you have a braze on, a standard front derailleur cage will
not be able to get low enough to allow the recommended 1-2 mm clearance
above the large chainring. Shifting works but not as well, with more
chain drops. I have a FSA compact 50-34. I recently replaced my
standard DurAce 9 speed front derailleur with a Campy Chorus compact
specific 10 speed front derailleur with remarkable improvement in
shifting.

lying
around) and everything continued to work fine. With only two
chainrings it
should be even easier. I have another bike that uses 48-34
chainrings, also
with Ultegra STI levers, and the derailleur on that is an old Suntour

XC-4050 that I fished out of my bits box.

But anyway, "compact specific" front derailleur is a solution to a
problem
that doesn't exist. It's just marketing designed to separate
credulous
cyclists from their money.

Will a Campy front derailleur work with a Shimano STI Shifter? The
reason
that I am asking is, that I want to use 10 speed Shimano STI
drivetrain
with
a compact road crankset (110 bolt circle with 50/34 chainrings).
Campy
seems
to be the only one making a compact specific front derailleur. I
main
concern is will the trim function of Shimano shifter work well with
a
Campy
front?
