Campy housings and Shiftmate for Chorus ergo levers and Dura Ace rear derailleur?

Hey everyone,

I've been gathering Campy parts in hopes of putting together a straight-Campy bike, but since it looks like I'll be a bit short of cash to splash out on the last parts I need (Campy compatible rear hub, cassette, and rear derailleur) for awhile, I thought I'd try to make something work with my current shimano-compatible wheels/cassette and Dura Ace derailleur.

After a little looking around I found the Shiftmate, and as far as I can tell I would need the Shiftmate 3 model to accomodate the Campy shifters (Chorus 10) with Shimano cassette and derailleur (both 10 speed). I also need some housings/cables/ferrules, and since I'm new to using Campy, am wondering whether I need Campy housings/cables or other special ones. I've heard some grumblings of needing Campy-branded housings/cables, but am not sure how accurate/diehard that is. Any thoughts (or is it just clear-cut that I need Campy stuff)? Does this setup sound reasonable with the Shiftmate? Anyone had good experiences with it?

Thanks in advance!

Cory

If you buy new Campy shifters they will come with cables. The only potential problem might be in using the new ultrashift levers with the Shimano RD. As long as the RD has enough spring tension to pull the cable down to smaller cogs, there will be no problem, but the new shifters don't properly if the RD has inadequate spring tension. A few people mixed the 2009 shifters with with Centaur or Veloce RDs from '07-'08 and found that the spring in paralleogram was not strong enough. The result is poor shifting to smaller cogs. The 2009+ ultrashift levers are more sensitive to cable friction and require the new Campy ultra low friction housing or another brand of 4mm housing with low friction. I've had good luck so far with Shimano housing and Campy cables.

I'm not a shiftmate expert but from what I know it's pretty straightforward which one to buy if you know what parts you're using.

As for cable housing, I suspect you'd be okay with Shimano or other shifter-specific housing that is compressionless and low-friction.

campy cables are different enough that they don't work with shimano right out of the box.

the brake cable head for shimano needs to be filled down in order to fit campy levers.
the gear cable is interchangable, as long as you use gear cable housing for shimano type.

but it's best if you don't mix them.

I've had great success using Campy 10-speed Ergo levers (2006 so pre-ultrashift) with a Shimano 9-speed 105 rear derailleur and 9-speed cassette with the appropriate Shiftmate (#2) and the Campy cables and housing that came with the Ergos have worked just fine.

AEO is correct that Shimano cables don't fit Campy levers. However, he is incorrect that the shifter cables are interchangable. Both the shift cable and brake cable heads are larger on Shimano-compatible cables so you must use all Campy-specific cables at the brifter end. At the other end of the cable, the brake calipers and derailleurs are indifferent to what you use.
