The discussion of the rare Campagnolo "cheater bar" reminds me of the rarest of all Campagnolo accessories - the 1977 Campagnolo CPSC reflector! It was only offered for a single year, and it came only on brakesets sold with Raleigh Pro's sold in America. Here is a photo :
It was offered for such a very short time that it never made it into the catalogues (who would have believed it anyway?) So rare !!!
I wish I still had mine but I put it on my kid's TREK JET and it fell off while we were out on a trail ride last year ...
