Most bottom brackets are reverse threaded on the drive side, so that you aren’t slowly loosing the bottom bracket as you ride. Well, if you have an older Italian or French bottom bracket, then they got that backwards. Awesome. Your BB is threaded the same on both sides, regular old right-handed.

If your BB says ‘36×24T’ on it, it’s Italian. Otherwise, look it up in Lord Sheldon’s BB database.

    some newer bikes still use italian component standards! i could be wrong, but i’m pretty sure colnago does, among others.
