Frame sources?
 

OK, I'm sure it's been mentioned but I can't seem to find anything on a search. I was wondering if there are any good sources for vintage bikes and parts? I've been thinking about a new project involving an older steel frame to build up.

I haven't found any consistent sources of parts, etc., for vintage bikes on the web that are as good and reasonable as eBay. Cyclart always has an extensive list of stuff for sale; check that out. The price is high, but you always get a fair assessment of the condition of the parts and frames, and who knows, maybe they'll discount one of their outstanding finishes...

There are a couple of sites that have some older, nice NOS frames out there: R & A Cycles has a bunch of nice Casati's and Reparto Corse has some cool Guerciottis and Mosers. I'm sure there are others.

For parts, heck, e-bay is probably about it or try a WTB in the ad section of this forum.
