    Need help with Klein Pulse Race serial #

    Can anyone id this frame for me? It appears to be a 1998 Pulse Race but I don't know what I'm looking at when it comes to the serial #. If you can id it please let me know how to break down the serial # so I can id another frame.
    Thanks for your help.

    Yikes - were you planning on a re-paint of the frame anyway?
    I don't know too much, but the "21" in the middle of the bottom line refers to the frame size. On the Pulse models (maybe others), there were 5 sizes: 18 to 22 inch, which was roughly Xsmall to Xlarge. So, a 21" would be a large.

    I have the same serial number format on my pulse pro i just picked up. I'd love to know more about it. My paint was black and destroyed as well so i did repaint it.

    Maybe I'll have to try again. Any of them happen to have this type of format?

    Ha, wouldn't it be funny if the Pulse Race frames actually started life as Trek 4300s.... wouldn't surprise me one bit

    I wanted to contribute another trek-era serial number to this thread:

    This frame is known to be a Pulse Comp in size 22" (XL)

    As far as I can tell the serial #'s are as follows:

    X
    K 003803
    4300 22 S1 1245
