    What is ‘BSA’ BB means?

    I know it is English-threaded.


    But what is really ‘B S A’ meaning?
    British Standard something?


    Tell me if you know...

    It stands for "Birmingham Small Arms company", which was the company that started the standard, after that BSA just stuck on the name.

    Boy Scouts of America. They sell bottom brackets like Girl Scouts sell cookies. But only threaded bbs.
    Oh, wait never mind. They are now just "Scout" bottom brackets and they sell pressfit..too.
