  1. I have a raleigh international, 1974, and the previous owner hit a car with it. The front fork is
    bent but probably fixable, since it wasn't bench much. However, the top tube is gently rainbowed
    near the headset and the nervex lug, the chromed ones on top, have some hairline cracks in the
    chrome. signs of stress but probably not major.

    I'm not worried about the fork because i did the same thing to my raleigh grand prix and it took a
    second accident before the fork was unfixable - but still it never failed on me. however, can the
    top tube be replaced on such a 531 steel bike at an affordable rate ?? who could do that for the
    supposed $100 i saw quoted somewhere. I'm in southern CA and most builders down here would probably
    charge a lot more. who specializes in such frame repairs, and if the lugs are pinned, how would that
    be done ??

  2. Ouch. Frame damage is not something to take lightly. You'll probably have to replace the down tube
    as well. And I would see about getting the forks straightened and aligned, if their only, as you
    say, slightly deformed.

    Most frame builders can do this. Use a real bicycle frame builder, however, they know more about
    bicycle frame alignment then an everyday brazer.

    Unless you are restoring the bicycle, however, or it has special sentimental value, I would
    gracefully retire it and look for a new frame.

    May you have the wind at your back. And a really low gear for the hills! Chris

    This is not a good basis for faith in the International's fork and there is a very high cost of
    being wrong about a fork.

    It sounds to me like this bike needs alignment more than a tube replacement. Frames that take a
    head-on collision and bend at the head tube often do not need the tube replaced at all, they just
    need straightening. Naturally it depends on how much it's bent.

    Anyway, anyone qualified to straighten the frame should be able to inspect and straighten the fork
    as well, and let you know if it's too far gone.

    "You'll probably have to replace the down tube as well." ?? We don't know that at all from his
    description.

    The earlier (Paul?) comment about getting competent in-person advice, and possibly an alignnent,
    seemed the more prudent approach, IMHO.
