I am glad I read this. I asked sort of the same question in bike mechanics.
I have a raleigh MTB I want to refurbish. I bought it 20 years ago. I want to refurbish both because of nostalgia, and because it fits me really well. The LBS said if I want a 'modern' wheel ( I am thinking of rhyno lyte) then I need new gears, shifters, chainring and chain. But if this is just normal maintenence anyway, I dont mind to spend the bucks and fix it up and pretend like Im 20 again. Its fire engine red, and I rode it until everything wore out--no maintenence at all
