    Older Specialized Hardrock bottom bracket?

    I have an older cr. moly Specialized Hardrock 17" frame, shimano 200gs components, 21 spd. I need to replace the bottom bracket. Does anyone know what size came on this bike?

    Thanks,
    lee

    How can I tell? I just picked it up at a yardsale for $10. It rides great, just some play in the bottom bracket.

    Thanks,
    I will remove it this weekend. How are the measurements taken for the bottom bracket.
    The 68 and 113.

    Shell is the hole in the frame that the BB threads into, end to end. The Spindle length is literal. Its the square spinning "axle-like" part in the BB itself.
    Heres a pic of how to measure Shell Width...
