Campy ergo shifters with 7400 Dura Ace (pre '97) rear derailleur. Possible to mate?

Hi guys, I'm new around here. Been reading for the forums for ages, finally signed up to participate! I'm pretty green with a lot of this stuff so I'm not sure how much help I'll be yet, but I'm looking forward to joining in the discussion.

Now , to the matter at hand:

I've got a Dura Ace 7400 (pre '97) gruppo that is currently running a 6 speed freewheel. I was planning on swapping my wheelset and picking up a freehub to run an 8 speed or greater cassette. I will need to swap out my 6 speed downtube shifters to do this and figured i may as well make the change to brifters. I was thinking about going with campy and using a shiftmate to compensate for the shimano/campy ratio difference.


Now all things being equal, i think this would work, but I've read about the pre '97 dura ace compatibility issues. I've also read that newer shifters 1 speed greater than the cassette will work with older dura ace rear mech...

Anway, my head is about to explode!



can anyone tell me if there is a way to mate pre '97 dura ace derailleurs with campy ergo shifters? I can't seem to figure it out.

Thanks in advance

That only holds true for newer Shimano shifters, ie. not Campagnolo. For more information, look here: http://www.ctc.org.uk/desktopdefault.aspx?tabid=3946

Sorry, my mistake, I meant to write 'new', that was the article I was thinking of.

Cheers

Dura-Ace 7400 shifter cable pull is very nearly the same as any Shimano 9-speed. A Shiftmate designed to work with Shimano 9-speed shifters and your particular RD should fix your problem.
