    identifying frame tubing

    I remember there was a thread about it within the last few weeks, but I can't seem to find the answer to my question: Can you identify frame tubing by flicking it with a fingernail? I was trying to use that technique on a (repainted) bike my friend picked up last night, and I noticed it sounded different on the middle of the frame tube vs. the ends near the lugs. Might that indicate that it's double butted tubing?

    You can get an idea whether or not it's butted that way, but you won't know for sure until you chop it up and look.

    How important is it that you know?

    Spam-B-Gone? I was just asking...
    It's not that important for me to know, it isn't my bike anyway. Just trying to get a better idea of some ways to be able to quickly discern whether a bike is a good deal in time sensitive cases where I'm not familiar with a particular bike.
