so...can anyone tell me what i need to make it work?
i would guess the hub would be 130mm, after a quick measure though it looks like it might be 126.
a RD that will work...what?
are there downtube shifters that will work or will i have to use something else?
i was running the bike without a front der. but i don't know that will work with 9speed, any idea on that?
it has dura ace 7400 right now...
1. All Campy 8, 9 and 10 sp are 130mm
2. Campy made 2 versions of 9 sp derailleurs and shifters: pre and post 2001. They have different actuation ratios and aren't interchangable. Campy 8 sp and early 9 use the same rear derailleurs. They are getting very rare and expensive. That's the bad news. Good news next
3. You can ugrade early 9 sp brifters to current 9 sp with an Ergo gear change. That allows you to use current 9 sp derailleurs, which are plentiful.
4. Campy 9 sp cassettes are all the same. There are no early versions. That's also good news.
IMO, if you want Campy 9 sp, use any post 2001 rear derailleur and and a set of Mirage brifters. Campy 10 sp rear derailleurs have narrower busings in the cages. An 8 or 9 sp chain is usually too wide to fit. So confine your shopping to derailleurs that actually say 9 sp. Good luck
