• Is that miche bb not just a British thread 68 shell width bb?

  • how can you tell? A friend of mine gave to me a while back and just said it was Italian threaded as he couldn't thread it into his British threaded shell. I'll be honest, I didn't think to check.

  • I'm not an expert, but all the Italian threaded bbs I've come across have had a shell width of 70mm, and it says bsc on it

    Sheldon brown:
    1.37 x 24 tpi is British ISO thread (shell width 68mm, 73 oversize)

    36 x 24 tpi is Italian (shell width 70mm)

    Just an FYI! And cos I'm after an ital. threaded bb :-)
