    tooth count IRO bb?

    have an IRO crankset and bottom bracket on the way.

    had emailed IRO to see what the proper BB tool was and the response was "a tool for any Shimano bottom bracket".

    now i go looking and there are all sorts of tools for Shimano.

    what is the proper tooth count (or proper tool part #) for the IRO bb?

    thanks from the noob.

    They probably mean that guy right there. Check out the pictures that they have on the site and make sure.

    no pics on the IRO site to compare.

    It's a standard square-taper sealed cartridge bottom bracket. As waldo said, takes the Park BBT-22 tool. (The old BBT-2 and the small BBT-32 would also fit). "Tooth count" is 20 teeth or, more accurately, splines.
