Campy 8 speed newbie

Hi all,

I am building a bike with 8 speed Campy ergo shifters (1991-1997 version). I am on information overload trying to figure out what is compatible with what, so here goes:

I have the 8 speed ergo shifters and 8 speed cassette but no rear derailleur yet.

Can I use a current model derailleur with these components? I have heard that it might work with a 9 speed chain, and maybe swap the derailleur pulleys to 8 speed? Apparantly Campy changed the indexing slightly in 2001 - some people say pre and post 2001 matching does work, some say it's not possible???

Also, the left ergo shifter (for the front derailleur) seems to have 12 indexed positions. Is this normal, and do I just set it up so 2 of the indexes move my front chainrings?

Thanks in advance.

Yes, a current model derailleur with 8 speed pulleys will work. I installed a Veloce rear der on my wife's bike, using 8 spd brifters and a SRAM 8 spd chain. It works fine.

Your left brifter is normal, works for double or triple cranksets. Adjust your limit screws on the der to get it properly positioned over the small ring, then install the cable. Make sure the shifter in the "small ring" position. How many clicks it takes to get the der to the large ring is what it is. (My bikes seem to be around 4 or 5 clicks IIRC.) Then adjust the limit screw for the large ring.

Thanks for the info nuovorecord.

I'm not sure what you mean by "My bikes seem to be around 4 or 5 clicks IIRC". Do you mean it takes 4 or 5 clicks to shift between front chain rings??? Surely it only takes 1 click? But hey, I've never used Ergo brifters before...

Thanks.

It's not supposed to work because of indexing differences, but I am running old 8s Ergo Chorus shifters with a 2006? Centaur rear derailleur. It works but it's not perfect.

For the front - one good push, but you will hear multiple clicks. It's different than Shimano, but has basically infinite trimming.

Yes, that's correct.

Good information from the other posters. That said, most all modern derailleurs dont care what kind of system your running. As long as the shifter cable pull matches the cog spacing on the cassette, and you use the appropriate chain for whatever speed system you got, then your derailleur should be able to handle it, providing the derailleur pulleys are matched for that speed.

I run campy 8-speed on my bike, shifting with 'Syncro ll' 8-speed DT shifters through a 'Shimano 600' 8-speed rear derailleur to an 8-speed Record cassette. The shifting on my bike is great, eventhough 'Syncro ll' does'nt have all that good a rep.

I've been looking at some similar setups. There is a lot of conflicting info out there on what works and what doesn't. I tend to trust the people who say "I have this setup and it works" more than the people who just dismiss it. There also seem to be a lot of combinations that work even though all the info says it shouldn't. Mostly you just have to try it and see.

The best resource I've found so far is this page:
http://www.ctc.org.uk/DesktopDefault.aspx?TabID=3946

He has a lot of data about cog spacing, cable pull, derailleur mechanical advantage, and how different RDs will work with different shifters. It takes a little time to get your head around it but it's good stuff. Here's what they say:

"Unlike Shimano, Campag's 9-speed mechs do not happily accept 8-speed chain, however their 9-speed chain runs okay on 8-speed sprockets, so best use that if you have to fit a new mech. And although in theory, this mech will overshift by 0.22mm per click in an old 8-speed system, Campag's website implies that it's near enough okay."

Great advice. Thanks everyone. I will proceed with sourcing a nice Record or Chorus rear derailleur in 8,9 or 10 speed knowing that it "should' work with my 8 speed Ergos!

While some say it works fine, most of us are less than satisfied. My Campy Daytona 10 works absolutely perfect every time. I could never say that about my 8 sp that used a current der.

There is a good reason that Campy 8 sp rear ders go so high on ebay. It's because they work better than late model versions. IMO, source the correct der for the job. You won't be sorry. Good luck
