I was given a home made fixed gear conversion yesterday, it's been sitting for quite a while but it's pretty much complete. The frame is an unknown, the wheels look to be Nisi Pista with French nutted hubs. The front axle is 10mm, as is the rear, they are built and dished properly too. The single cog in the rear is held on using a BB lock nut.
The frame is marked 531, by the look of the three holes in the head tube its a Raleigh frame, maybe an old Super Course. The tires are all but rotted away.
Now the big question, do I dare buy new tires for this and try to ride it on tubulars? I'm over 300lbs. Old school thinking says no way, but I figured I'd ask since a lot has changed in the past 30 or so years. The old tires came right off, as did most of the glue. Pretty much just dust where the glue was.
If not, I might as well find someone that needs a set of tubular wheels to swap with.
It's a shame because they're dead true and they don't look like they've ever seen a brake caliper. They have been ridden and show some age but considering I got the whole bike for $20, if it had tires, it's rideable. I wouldn't mind trying a fixed gear bike but I don't think I care enough about it to build a new wheelset.
However, after pricing out tubular tires, it may be cheaper to build new wheels than by tires.
