Again: Campy shifters, DA drivetrain(9 posts)

Again: Campy shifters, DA drivetraint5rguy
Sep 10, 2003 7:57 AM
My question: can I use a DA rear derailler and cassette with Campy Record or Chorus Ergo shifters? After reading many posts and the hubbub site, I think (but am not sure) I have to use the 10-speed shifters (because of cog spacing) and use the cable routing as described.
Am I right in thinking the 9-speeds (either post-1997 or pre-1997) will not work?

Sorry to beat the same drum again! Will post my experiences if the solution offered works!
Exactly wat are you asking here?the bull

Campy 10 shifters will not work with Shimano 9 drivetrain.

What are you tring to accomplish and how much money do you have?
Please try to be clear!
yes they will...C-40

You haven't read up on this subject. Campy 10 shifters will operate a shimano 9 derailleur if the cable is misrouted under the cable clamp to increase the lever arm on the shimano derailleur. Apparently it's a fairly common practice among tandem owners who want ergo levers with their otherwise shimano drivetrain. Campy 9 shifters would need to have the rachet wheel changed to a 10 speed model to make this work.

Another method of adapting different shiftera and derailleurs is at this site:

I have read up on the subject. I found posters that say 9 speed will work, and posters that say only 10 speed will work. The 9 speeders seem to be of the ''practical'' school (if it works, it works), the 10 speeders have a good theoretical argument why 9 speed shifters should'nt work (not good at least).
In both cases the different cable route fot the DA rear derailler is necessary.
So if there's any more real life experience with the 9 speed shifters, please let me know. Thanks.

There are two ways to go:

1. Campy 9s shifters and Campy 9s derailer. This will shift a 9s Shimano drivetrain just fine.

2. Campy 10s shifters and Shimano 9s derailer--using the Hubbub cable attachment method. This will also shift a 9s Shimano drivetrain just fine.

I'm using approach #2 (Centaur/Ultegra mix) and it works great!

... will work with a Dura Ace 9 speed group. I just installed a new product called Shiftmate, made by Jtek Engineering....
and I can say the combination works flawlessly. I posted concerning this earlier, but hadn't yet tried it out. It involves a pulley with two grooves of different depths that installs just before the rear derailleur. It changes the gear pull ratio. Jay, who designed these, sent me one, but I'm not sure if they are on the market yet. I'm thrilled with the ergonomics of the Campy levers over the Dura Ace and the shifting is lightning fast. I'm planning on getting 2004 Campy stuff next year, but I was tired of the ergonomics of the Dura Ace levers in the short term. Hopefully, my wife won't figure out there isn't really a good reason now to switch to a new groupset :)

Run a Campy rear der. and brifters and Shimano everything else, and keep on trucking.

I've done the Campy 10 brifters/der on a Shimano 9sp cassette and it worked great.

Why go through all the rigamarole when running the "right" derailleur will save you all the hassle of adjusting, fiddling, running adaptors, etc. Its not like road derailleurs will wear out before you upgrade anyway!
