I've read prior threads in this group that seem to indicate that
9/16"x20 pedal threads are really very standard, yet I still find that
generic new pedals don't fit my old (probably mid-'70's) Raleigh
Sports. They get about a half-turn in and that's it. I have three old
sets of pedals (in five years I've broken three pedals, all on the same
side; what's up with that?), two of them Raleigh-branded and one
unbranded but "for Raleigh", and they all thread in very easily.
They're all visibly the same diameter and all 20 tpi (I've checked with
a thread gauge). Under certain light I can almost convince myself the
new ones have a different helix angle, but I have no tools to quantify
that parameter or thread angle.
Any comments appreciated,
