can i get away with?
i've got an old motobecane that is an entirely unspectacular frame, but it was my first fixed gear and holds some sentimental value. i know the bottom bracket has been rethreaded at least once, and it's held up quite well, but i've stripped a few plastic caps in it and now the threads are starting to look damaged (cups still thread in smoothly, but it looks like some of the threads are chipping off).
my question is can you rethread an already rethreaded bb shell? will it work as well as the first rethread? will it not last as long?
this frame's been good to me, but i don't want to throw a lot more time and money into it if it's not worth the effort.
