Currently am running a 105 FD on my 50/36 Bontrager compact, and shifting is OK. I'm building up another old frame, and need to acquire a FD for it. Would you recommend just getting a FD for the frame, or going with a compact FD (thinking maybe Campy Centaur) for my current ride (LeMond carbon/steel spine w/clamp on FD)?

not campy...

If you will use shimano shifters, a campy FD doesn't make much sense. Stick with a shimano product. The shifters work quite differently. Shimano uses a single click to quickly release the cable needed to make the big ring to little ring shift, while campy's shifter action is more gentle, using 3 clicks to do the same job.

you only need a 'capacity' of 14 teeth with a 50/36 crankset. shimano FDs are designed for this, no probs. they even work ok for most 50/34 cranksets (16t capacity).

the FSA Compact FD is 16t capacity-specific. i doubt it would offer any improvement over your current FD.

though how is the shfiting now?

FD is shifting OK now, probably could tweak it.

This is a question about optimizing front shifting. Since I have to get a new FD for either the old frame or move the 105 from my current ride I'm thinking getting a compact-specific FD for the compact crank makes sense (although I'll pay a bit more than for another 105 FD).

I'm currently using 9-spd 105 STI, but just picked up some Centaur 10-spd levers I'll run w/my Ultegra rear via the hubba-something-cable-redirect-conversion w/a 9-spd SRAM cassette.

I have a new FSA compact FD that I will give you if you come and pick it up. FSA seems to have missed the boat or has a quality control issue with the 10 speed FD. The cage is at least 1 mm wider than my Dura Ace 7700 FD - and that was designed for 9 speed chains. The FSA FD might work for 10 speed chains if it is squeezed but I am not willing to go to that effort when the 7700 FD works fine.

I've been using the stock Ultegra 10 speed FD with my FSA compact crankset with no problems. When I had my LBS install the crank, I had ordered the FSA FD and they could not get it to work right.
