do I need new rear derailleur?

sundog-<< I am building up a new bike with Campy 10 speed stuff. I have an older 9 speed derailleur
which I would like to use. Campys Q&A section states the following >><BR><BR>

What crappola...I wonder if they have tried it. If the rear der is not worn out, it will work with
10s shifters w/o modification...try it...

I have put 10s rear ders onto old 8s systems and have used old, like a 1996 Athena on 10s
systems...just try it.

Q Does the 9s rear derailleur work the 10s drivetrain?

A Absolutely not. There are major problems with that lateral clearance and excursion, and with the
geometry of the parallelogram.

My 2003 Record levers work perfectly with a 9sp "Titanium" rear derailleur. It's old and pre '91. I
didn't change the pulleys or anything. The same derailleur has been in use with Campy 9 and 10 for
about 5 years and I ride thousands of miles/yr.

What do you think this is, a racket? This is NOT the Shimano STi Department! Relax!

Any post 1992 Campagnolo rear changer will shift any 8, 9 or Ten Campagnolo system. It's so logical,
but a lot of people expect it to be hard. I'm afraid Campagnolo has gone over to the "buy more"
side. You'll find that pre 2000 stuff works with itself better than mixing pre and post 2000 ( that
is the year the B screw moved from the upper pivot to the lower).

And the wearing part of your system, the indexing springs, fit all models made after 1987!!

This seems a little hard to believe. Has anyone found this to be true? If I need a new derailleur
I would rather find out now so that I don't have to mess the chain twice. Could this just be
marketing hype to get me to drop another 200 bucks or is this really true?

You can surely trust Qui si parla Campagnolo and Andrew Muzi....I just converted a Record Triple
nine speed to a 10 by changing the front right shifter, chain and rear cogs. It works!
