I have more pictures from the seller for the Derosa that is attracting so much attention----ebay link here:
For what it is worth, appears to have been ridden in the rain for sure and if it was hung vertically after such a ride, then I would bet there is rust inside the chainstays near the rear dropouts--not the place to have a weakness in your tube wall in my opinion. Also, for prospective buyers, the front derailleur is missing the screw and nut that holds the cages together at the rear of the outer cage--not a deal stopper by any means, but worth noting. If you want the zipp package of pics, email me off-line. Or, you San Francisco dinner goers could just buy it and dissect if over Italian food on 7 November. Lou Deeter, Orlando FL
