  1. I know that at least one company offers a kit to change from the old single
    piece to a standard 3 piece, they sell the kits at harris cycle via
    www.sheldonbrown.com and was wondering if anyone has done this and what the
    outcome of the conversion was?

    The outcome was a 3-piece crank in an Ashtabula-sized BB shell, which
    allowed better bearings, less weight an triple chain-rings.

    The conversion was done with a kit not purchased at Harris Cyclery, but
    as far as I can tell they all work about the same.

    Remember that you need pedals, too. Worked well on the two that I've
    done.

  4. Just wondering, what kind of bikes did you do this too? I have this old
    early 80's murray 10 speed. It's in nice shape but still has the single
    piece crank yuck!

    One was an ancient GKW[1] with 26" EA3 rims that was being converted
    into a pseudo-English-roadster, and the other was a 1960s-era Schwinn
    touring frame.

    [1] GKW= God Knows What. In this instance, with no badges, no
    decals, and a fresh coat of paint that had been applied after far more
    work than the frame was worth in my opinion.
