Fantome Fixed

We all know about NJS export as a resource for importing crashed out, candy colored frames made out of obsolete tubing. But what if you wanted a crashed out, chromed out European track frame? Check out Fantome Fixed. They run a similar operation to NJS Export, they go around to several velodromes, buy up old (mostly French) bikes and sell them off their blog. Heres a few gems.

They're pretty affordable compared to an NJS frame but the quality is dubious in comparison as these are pretty obscure builders using older tubesets. I'd watch out for the hard to replace French threaded bottom brackets and headsets too. They also have a decent selection of vintage parts to go along with their frames if you're serious about building up a vintage French bike.
