    What tool do I need to take this bottom bracket bearing cup out?

    Any help would be appreciated! There are eight grooves in it. Thanks!

    I demand a recount!!! (just getting in the spirit of the upcoming political debacles, or whatever that nonsense is that we'll be inundated in for the next three months)

    Actually, it's pretty clear from your picture that there are 12 splines.

    The only BB's that I know of that use that kind of BB interface are Campy's. The Park BBT-5 is the correct tool for that BB. And, it also works on Campy cassette lockrings ;-))

    Wrong. It's from a Shimano FFS "Octa joint" bottom bracket:
    http://www.sheldonbrown.com/shimano1982/pages/35.html
    It uses an old-style Shimano freewheel tool to remove them:

    Note that this is the pre-1985 style remover. Later-style freewheel tools, like the Park FR-1:

    will not work- they're larger in diameter.

    I would love that. Then everything would be cheaper, more people would bike and understand biking and the environment would be saved. YAY!

    -ish. At least the FFS cups, once extracted, will reveal a "standard" English-threaded bottom bracket shell.

    The wonderful thing about standards is that there's so many to choose from.
