Well, a glass of red wine and some fine local cheeses and I feel positively relaxed!
to be honest, I don't think many people will be that discerning to recognise what sort of bike you are on anyway, so I wouldn't worry.
My life, what are you saying, that Joe Public will be unable to spot some finely crafted, old steel when they see it? I am crushed
Do you mean to say that in some way you might be undeserving of the bike? I reckon that might be true if you were a 'rich prat' who never used it for the purpose it was designed for. To me the bottom line is that you have paid for the bike, which unless you are rich (not necessarily a prat!) you will have had to work for. So you should feel as though you have 'earned' the bike and are therefore deserving of it. And since you obviously ride (and well if other posts are anything to go by) then that marks you out as a (retro)biker, hence not a prat!
QED - case closed!
I'm loving the way you're putting the case there - not only am I demonstrably not a prat but by jove I DESERVE the bikes I ride. Now if I can only explain this as succinctly to my wife.....
PS People above are being kind about my riding although I'm, not so modest to say that I don't rule on gentle fireroad climbs
