Oh shit! Are you OK though? That's the main thing.
The dawes linear was dawes' top of the range frame back in the day. Its a raw/unpainted finish with decals lacquered over - original factory finish.
I have another Ribble(!) slightly smaller though (I think it's a 55cm) and built up as a geared 8 speed at the moment - I don't think I can bring myself to strip the group off it as it all rides amazingly.
Both are 653.
For a wildcard, I also have a Specialised Langster that I'm just finishing off...
Are you in Oxfordshire anytime soon? You're welcome to take a look otherwise I can send some photos at some point this week.
