Shimano Ultegra Triple Front Mech 10sp 6603
If I choose the option "28.6mm/31.8mm" can I possibly use this with 2 different seat tube frames? I'm going to use this for 28.6mm seat tube chromo bike for the time being and am going to upgrade another alu frame with 31.8 seat tube.

Answer: 
Yes, this derailleur comes with a spacer/shim to bridge the gap between 28.6mm and 31.8mm; making it compatible with both diameters.

Answers

Answer: 
This derailleur is not designed to run with 9-speed shifters of chains. It could be setup to run with a 9-speed shifter but will not perform optimally; also as the cage is narrower for 10-speed chain, chain rub will occur.
