Sounds neat. How about some pics and a road report?
I've been slowly gathering up circa mid- 80's Gipiemme bits mixed with Campy Triomphe for a Basso. The style for both marques in that era are blocky, hard edged cool. That Exploit rear derailleur you have is clean lined vs. the Triomphe.
Sorry if I'm only talking of the aesthetics as I've yet to finish building the Basso. BTW: Curious if your bike is complete with Gipiemme pedals, what type? Was there ever an Exploit pedal?
