So what do you do when you don’t want to pay $100 bucks for a bottom bracket? you ghetto-phy an old one to make due.

Start with a Sugino bb

mill some stuff, tap some holes, get some duct tape…. presto

    Most impressive dirtbaggin there, my friend.
    Did you turn the bearing races after weld by chance or are you going to run it as-is?

    Darned good stuff.
