I want to use drop bar shifters (Ultegra 10-sp STI) with a 44-32-22 crankset (Raceface Deus).
Would an Ultegra front derailleur work? Do I need to get a new Ultegra 6700 (10-sp) front derailleur or would my existing Ultegra 6500 (9-sp triple) front derailleur suffice? Will either work with a large chain ring of only 44 teeth?
I've been happy for 35k miles with the latter and a large chain ring of 46 teeth....
Front derailleurs don't have a minimum sprocket size, just a maximum size. It might look weird but you dont really have any other good options. MTB front derailleurs won't work with road indexed shifting.
You might get smoother shifting with a 10 speed derailleur.
The photo is deceiving.
The curve of the cage does not follow the chainring very well.
The result is the trailing end of the cage is quite far from the chainring, making the middle-to-large shift sloppy.
