So based on comments above I got back into my stash to look for a RD-7700 since the RD-6600 is a longer cage. Realized I have a complete set of DA 7700 parts I could put on this minus the brakes. But I do have a set of BR-7800 so could really go this route. Dang decisions......
Whatever I use is going on this bike since it's pretty much mint and deserves so much better than the Exage stuff on it. I do have some Dura Ace hubbed wheels on it right now.
