There is a rust bucket Cambio Corsa bicycle on ebay (1079595748) that is
listed as a Bianchi. I emailed he seller to tell him the head lugs and seat
stay attachment identify it as something other than a Bianchi, as I'm 99%
sure they were using their proprietary headlugs and headset at that point.
Dave in Martinez said it has the same fork crown and similar lugs to a
Cinelli Riviera that he is aware of. I imagine there were a limited number of
high quality lugs, crowns and BB shells available at the time, high quality
meaning grotty sand castings that with enough filing could be made to look
pretty good. Any body know what it is?
