I take that it is Dave Schnakenberg who is offering up a no-name frame with a Paris Roubaix gear on ebay:
It seems like quite a good opportunity, however I would like to point out that this frame was not meant to be used with a Paris Roubaix gear. It was designed solely with the use of a Cambio Corsa gear in mind. This can be seen by the fact that the drop-outs have 17 teeth instead of the 19 used for bikes built for use the Paris-Roubaix gear system. You could perhaps run into problems if you want to put a 5th cog onto the bike.
