Campy 04 Record Shifter with Shimano 04 Derailleur(7 posts)

Campy 04 Record Shifter with Shimano 04 Derailleurglia

Does anyone have knowledge regarding the compatibility between these components. I would prefer to be able to use a Campy shifter but at the same time would love to leave the rest of the bike Shimano. Does the new 10 speed come close enough to allow the shifters to be used with Shimano's rear derailleur?

Throw ratios are different between campy and shimano RDs.Sometimes it works because of serendipity,and sometimes the cable mount to the rear derailer can be fudged to make it work.Also, cog spacing between campy and shimano 10 speeds is different by about .22 mm or so.
Don't know about the derailleur interchangeability...Spunout

but if you center the RD while in the 4th or 5th cog, you will only be 5 or 4 shifts either way. That would be a maxium of 1.1mm error. Looking at my 10 speed system, 1.1mm isn't going to mess up my shifting.

So try it out and let us know!

If I've read correctly, the new DA RD works backwards like the XTR. If so, it would be weird to perform shifts to larger cogs with the thumb buttons.

It's also known that a 10 speed Campy shifter pulls too much cable even for a 9-speed Shimano derailleur. The campy 10 speed shifter will operate a 9-speed shimano derailleur, only if the cable is routed under the cable clamp to lengthen the lever arm on the derailleur and shorten it's throw.

I see no advatange to this proposal, unless you really need the 12-27 cassette that is not offered by Campy.

Really.New one on me.Where is the info on that?

....the confusion might be due to some description in an article regarding the derailleur parallelogram linkage. On the new derailleur the second part is now keyed to the inside of the parallelogram instead of the outside. On DA that's the only part wich is reversed. See XTR image below for a comparison.
probably misinformation...C-40

Some major magazine that I subcribe to published early info that claimed the DA 10 RD would be in the "rapid rise" configuration, like XTR. Apparently this is not the case.
