I would love to see a scanned copy of Frank Berto's 1980ish article on derailleurs. If I remember it was a two part article and came to me at a time when I was making a new derailleur purchase. I decided on a an ARX Suntour but all my better angels knew that the Campy anything was a better choice based on love not function. (Love of those who did the design, not only my love of things Italian.) Is it possible to post the article here on the list? Garth Libre
