If I have campy ergo shifters and a cassette spaced with campagnolo spacers buth an ultegra rear derailler will everything work right?

Depends on your definition of "right"... it "may" shift, due to the built in slop of a Shimano rear derailleur, but it certainly won't work "right." It may shift, but it won't be perfect and it won't be smooth. The spacing that a Campy derailleur throws per shift and a Shimano derailleur throws are not the same. You are best off to get a Campy derailleur, but as a temp fix, your Ultegra may work. I just wouldn't suggest using it all the time and certainly don't expect it to shift like it would on an otherwise Shimano drivetrain.

I could be wrong, but I have seen this tried a few times at the shop I work at.. it never works as good as the customer hopes, and they often bring it to me to ask why. Not the same spacing in the cassettes and shifters... so they are not 100% compatible. They may be like 80% compatible, but just get the Campy derailleur and be 100%.

Dura Ace rear derailleur and it worked fine. I helped him set it up and it did take me a long time to get it dialed in perfect although it did work.
Why do you want to do this?the bull

How many speeds do you have?I am assuming that you cant find a 9 speed derailleur for campy.

because I have the derailler and the cassete lying around and I'm building up another extra road bike and I'm being given the shifters. I'm trying to spend as little as possible here, but if I have to I will.
what model are the shifters and how much do you sell them for ?PeterRider

The cable pull per shift on ergo levers is not the same as shimano. I assume you have a 9 speed cassette.

You need a campy rear derailleur to work with the campy spaced cassette and shifters.

Another option that apparently works to some degree is to use a 10 speed campy shifter with a shimano rear derailleur, which has the shift cable routed under the cable clamp on the derailleur. Apparently the reduced cable pull on the 10 speed shifter and the reduced travel created by routing the cable improperly work together to produce aproximately the correct shifting for a SHIMANO spaced cassette. The site below has details.

So two wrongs makes a Shimano!

I'm using the technique described on the hubub site; Centaur 10-speed ergos talking to an otherwise Ultegra drivetrain. It's still in the experimental stage, but on the workstand, seems to work like a charm.

I've put 2200 miles on a Centaur 10v ergo shifter talking to an XTR derailleur and the shifting is perfect. Just follow the hubbub directions.
