initially posted this in Fix/SS forum, they reconed i'd have more luck over here
Recently bought this frame as a pre converted fixed gear. was lying in the back of a bike shop. The whole bike was very cheap. Stuck some deep V's on it, a new break lever and a bigger back cog. It’s got no markings on it at all apart from the knackered paint job and a bit of decal...
I don't really know too much about bikes in general but every bike shop I’ve taken it into has been seriously admiring the frame and I’m wondering if I’ve picked up a bit of a bargain. It’s got a 531c sticker on it, that might have been stuck on for show but its light as hell. In fact it's lighter than alot of my friend’s pretty expensive fixies. I’ve been doing a bit of research on the steel type and it seems to be fairly high quality competition racing steel. You can just make some lettering out on one of the tubes. It looks like "PH" or "FH"?
Anyway, if anyone has any ideas it'd be great to know what type of frame this is. If it's a good'n I’d quite like to restore it to it's original paint job. If not then I think I’ll just powder coat it black.
