Help identifying this frame This frame used to be black with a campagnolo sticker though under it I found a green layer of paint. When I went to set it up they told me it's probably an old UK or Belgium bike. For what i can see the frame number looks like 81    6836.

Well the wheels, chainring, cranks, chain, singlespeed thing, and single front brake are all non-original.   I'd even suspect the headset has been replaced - it looks far too new.

I'm going to guess its a Raleigh or otherwise English frame from the 80s.  Here's my old 1981 Raleigh Arena, and while the lug cuts are different, the seat stay caps look very similar.


Also, one of the main similarities is the rear brake bridge, which is a plate of metal welded to the seat stays where a nicer bike would have a more-elegant brake bridge.



So no its not exactly this bike, but its this era and down at the lower end of the price range.

I'd be surprised if its chromolly steel - that always feels surprisingly light for a steel bike.
