Replacing an Ultegra 6500 rear Derailleur with what?
Any suggestions on replacing a 9 speed Ultegra 6500 rear deraileur? I have a 3 speed Dura Ace crank and 105 shifters. Can I use 6600 or 6700. Should it be short cage or long cage? I also torqued my chain. So should I replace my cassette as well. I have about 9,000 miles on these parts?
