Thanks for the comments, folks, and particularly bigbossman for the offer; I like the idea of adapter hardware, though, because there's something perversely appealling about mounting beater Campy on my beater bike ... unfortunately, the drop bolts (see image from Sheldon's site below) which Harris Cyclery used to sell aren't in stock any more. Anybody know where I can find 'em? If not, I may take bigbossman up on that offer ...
