    A cool thing about Schwinn bicycles is that many of the parts were date code stamped.
    has anybody been keeping an eye on these and noting what they came from to put a date range to them? here's a bottom bracket and crank the came out of a frame serial #'d to 1949.

    I would like to bump this thread. I am eager to learn which parts were coded, and the method behind the madness.

    Not many parts were dated until the mid 60's. I've noted a few years back that the blade forks were dated with month and year stamping on the inside of the left leg just above the axle slot. earliest one I've had was 1961.

    Really? I didn't know they started so late. In that case, replacing the broken parts on my bike shouldn't be all that stressful. It was made prior to date coding, if that is the case.
