I'd love to see photos of your friends Echelon. I presume its a racing frame, not a sport tourer like Bob's?
My friend Jeff Linder rode the Echelon that I now own for Team McCall in the mid-eighties, sponsored, if I recall correctly, by a motorsport business and pizzeria. Could this be the team you are referring to?
All the earlier discussion on the CR list suggests that Echelons were built by Cherubim, see the links in my other email on this topic.
