Mixing Campy and Shimano....

This is pretty interesting. Apparently you can use Campy levers to operate SRAM drivetrain. If you don't like the double tap feature but want to try SRAM this would be an option. Also, would give you the ability to use campy levers and still run your shimano wheels.

SORRY - title was supposed to say MIXING CAMPY AND SRAM! :crap:

Another interesting way to do this is with a little part called the J tek shiftmate.

I've been using one with Campy Chorus shifters and a Dura-Ace rear derailluer and cassette. Works like a factory setup. In the past I tried the American Classic conversion cassettes, but they always had at least one gear that would be toublesome. With the shiftmate, I can't say I've missed a shift due to anything other than pilot error, and the Shimano derailleur and cogs are cheaper and lighter than the Campy.
The only problem is that it looks a little weird with the components mixed, purists may find it disturbing.

anybody tried sram shifters with campy everything else?

This topic is being discussed on other websites, too. I don't agree with Zinn's measurements. I've measured the cable pull on a Campy 10 RD and only came up with 25.5mm. In addition, the cable pulls are not all the same. The first five are only 2.5mm each, 6-7 are 3.0mm and 8-9 are 3.5mm. By my calculations, the RD will be off location by about 17% after five shifts, stay that way through shifts 6 & 7, then get a better on the last two shifts. After 9 shifts, the difference is only 6%.

A SRAM shifter is supposed to pull a uniform 3mm per shift, for a total of 27mm, according to the SRAM video on their website.
