Hmmm ... that is interesting. There is a slight difference from the article (3.1mm per click SRAM vs. 3.0mm on Campy), but apparent Zinn says it works.

I'd just run the Jtek shiftmate. I've used one for a couple of years on my old road race bike (Campy shifters I like, but Dura Ace rear and cassette for wheel swap/support) and it shift perfectly once set up.

A lot of people question that article. Consensus was that it can work, but not for everyone. Depending on which gears you use (some people never cross chain), which cassette sizes you use, cainstay length etc.
