Just when you think you have heard it all, something new comes along. My buddy Bill, a 40 year bike shop owner and mechanic Par excellence, tells me that in the 'late '70s or early '80s there was a Zapp (sp?) electronic or electric derailleur that cost something like $1300 way back then. He said it was so expensive that bike leagues banned it from competition.
I was flabbergasted...never heard of such a thing. It would seem to be within the CR timeline, yet searching the archives produced no hits at all. I almost suspect my leg is being pulled a bit.
Any of you sages familiar with this?
