Yep thanks to Engineering101, that's right. Sorry I should have put it in the ad. Its at my parents, where it was supposed to be available for pottering around there, but I just haven't got there enough.
Will take a reasonable offer if my price is too far out.
If it's pink, I'd take a stab at it being a 700, which means Reynolds 2070 (653 equiv I think) tubing. Might be wrong.
I have one waiting to be built up when space in the stable becomes available...
