I recently got this random frame for free and try to identify it for my project.

Some details:

- Bocama lugs (BCM logos on lugs with numbers 67 and 70)
- "B10023" on the bottom of the top tube
- Suntour headset
- Simplex dropouts
- BSA bottom bracket (68mm)
- was originally (splatter) colored with bright red/orange, white and possibly green (some remains were found under the terrible blue/black paint)
- quite long frame (seat tube 51,5 c-c, top tube 57 c-c)
- stem steerer diameter 21mm, seat tube diameter 26.2mm
- rear fork width 126mm, front fork width 99mm (approximations)
- probably used to be a 26" MTB or hybrid due to the brackets for cantilever brakes for 26" wheels
- no other text or numbers found on the frame

See pictures before and after removal of the ugliest paint ever.

Thanks!

unusual to find a 26" Mtn. frame with lugs, certainly rare to find one built with BCM lugs and Simplex DOs. Given that and the splatter paint and serial number, I'd say it's a European-made (maybe French) frame from a major brand and mid-'80s era. First thing I thought was "Peugeot", but looking at their catalogs this doesn't seem to be one. Unicrown fork might be original, but could be a replacement: are the forkends marked?

Wait. You removed the cantilever brake bosses?

I don't get that either, I wonder what the plan for brakes is?

Looks like he is going for a fixed gear since he also cut off the RD dropout, I would guess there is no plan for brakes.

I wonder if the OP's name is Drew.

Same color could be found on the fork, too.

As some of you are asking why I removed the cantilever brake bosses, it's going to be a single speed and no need for them.

Thanks for ideas, not the easiest one to surely identify

The frame is in Finland, so your guess about Europe could be right.

Whatever it was, it isn't anymore.

When does a single speed not need brakes?

When it is ridden on a track. Only then.

That would be fixed/track. Hmm. Fixed MTB?

Well, a track bike has only one speed. I was just answering your question. I've seen a few fixed MTBs. All of them had brakes.
