campagnolo 9sp indexing

Does anyone know the situation with 9 speed indexing compatibility between the different years of
groups? On the Excel web site they have the following.

"The right-hand 9-speed control had to be adapted to the new geometry of the 2001 Record 9-speed
rear derailleur. This control now includes a new indexing mechanism which makes it incompatible with
previous 9-speed rear derailleur."

So does this mean that in 2001 they made a change in the cable pull of the lever that makes all
pre-2001 9 speed different than after 2001?

I'm also wondering if a campy 10sp derailleur with work in place of a 9sp.

Just trying to understand the differences between the models and years and indexing/cable pull.
Maybe there is a web site that explains this in more detail?

Thanks

Jay

In practice, we use current Campagnolo rear derailleurs in systems all the way back to 1992 eight
speed. They work just fine. I have never seen a case of early/late Ergo or early/late changer
incompatibility.

I think the theoretical difference is probably less than the float in the upper pulley.

Occasionally we get a call from a customer asking if his new nine speed bike should really have come
with a "ten speed" changer. They seem the same to us in all respects except the nameplate and the
upper pulley.

Not true at all...we use 9 and 10s ERGO(2003) with old(like from 1993/4/5), not worn out Campag
rders all the time. Additionally, we use new(2003) rders for older ERGO(like 1992) w/o any
modification...all works just fine.

<< This control now includes a new indexing mechanism which makes it incompatible with previous

Not true in our very extensive experience...

<< I'm also wondering if a campy 10sp derailleur with work in place of a 9sp.

Yep, we even put a Record 10s rder onto Colby Pearce's 8s system, worked great, no modifications.

I'll make it simple, you can use ANY Campagnolo rder that was produced from 1992 until now with ANY
Campagnolo ERGO produced from 1992 until now...just match the number of cogs with the 'speed' of the
ERGO shifter.
