Shimano front derailleur compatibility with my shifters- 9/10 sp?
I'm fixing up/building up my Jamis Quest Femme and need a new front derailleur. I have ST-R700 shifters (Ultegra level 10 speed) and a FC-700 crank (also Ultegra level 10 speed, kind of an Ultegra predecessor). Rear is all matching 10 speed as well (6600). I happen to have a 6500 front derailleur which was made for Shimano 9 speed systems. Does anyone know if I can use this derailleur or should I buy one specifically for a 6600 or 6700 10 speed groupset? I found some compatibility charts online but didn't really help with the 6500... maybe front derailleurs aren't so picky?
