campy & shimano 9spd compatability(6 posts)

campy & shimano 9spd compatabilitygamara
May 19, 2002 6:03 PM
Not trying to open a can of worms or be flamed. I'm finally putting together a new ride and finally putting the old 7spd to pasture. My old bike was a mutt that had a little of everything from dura ace, superbe pro to chorus. I'm trying to stick to a budget for this project and thus don't have a gillion $$'s to work with or else I be going top end all the way.

I would like to know if 2000 chorus 9spd ergos will work with a shimano 9spd rear derailleur and cog combo? Will this shift as smoothly and as quietely as if it were all campy or shimano? If this info is already available on the web, I would appreciate the address or if someone has personal experience with this already, I greatly welcome your input.
you'll need a campy derailleur. nmweiwentg

The cable pull of the campy shifters will not match the requirements of the shimano derailleur and the shimano cog spacing is not the same as campy. 2000 model ergo lever are also not the same as 2001 and newer shifters. Campy changed the 9 speed derailleur design in 2001 to make it similar to the 10 speed model, and altered the amount of cable pull. See the exerpt from the brandfordbike.com website:

Please note that Campagnolo has changed their 9 speed rear derailleurs in 2001. They are now modeled after their lighter and faster shifting, 2000 10 speed rear derailleurs. Campagnolo 2001 9 speed rear derailleurs are NOT compatible with 1997 to 2000, 9 speed Ergo levers unless you upgrade to a new 2001 Ergo Cam. However, your current 9 speed system is NOT obsolete! All of the 2001 and 2002 9 speed cassettes and chains will work with all Campy 9 speed systems.
If you wish to upgrade your 1999 - 2000 9 speed system all you need to purchase is a 2001/02 rear derailleur and a 2001/02 Ergo lever 9 speed Ergo cam. Another cam will fit all 1992 to 1998 8 and 9 speed Ergo levers and allow them to be used with a 2001/02 9 speed rear derailleur.

The ergo levers can also be modified to 10 speed shifting and used with a shimano 9 derailleur as described at the following website, but I sure wouldn't recommend it.

the latter actually looks like the better solution. thanks!
why wouldn't you recommend it?
lousy cable routing...C-40

Take a close look at the pictures. Misrouting the shift cable under the sharp edge of the cable clamp won't provide good cable life. These guys should have a machine shop make an extension for the derailleur arm that would allow normal clamping of the cable.

Also there's a lot of time and fair amount of expense converting an ergo lever from 9 to 10 speed. If you go to all the trouble to convert the ergo lever to 10 speed, buy a Centaur rear hub, 10 speed cassette,front and rear derailleur and a 10 speed chain. Then you'll have a real campy 10 drivetrain that will work properly. Otherwise, just buy all Shimano parts and have a properly working shimano 9 drivetrain.

Works very well. In fact, I think that 9sp Campy levers and a Shimano rear derailleur/cassette shifts better than straight shimano.

This is from someone who is currently riding the setup that you mention.
