I have a Peugeot PGN-10 from somewhere between 1984 and 86, and it's a beautiful, fast ride I really enjoy except for one thing: I have a persistent mid-back problem, and the drop bars make it hurt. Long story short, I want to put North Road handlebars on my Peugeot. I know it'll look funny, but hey, I'll be able to ride without getting so sore!
I'm trying to determine if I need a 25mm or 25.4mm bar. The current stem and bar are CTA. I've tried to measure it, but without a nice caliper, it's mighty hard to determine a difference of .4mm! Were all the CTA stems/bars post-1984 25.4mm?
