    What's the best way to rid your bike of rust inside the frame. I think my bike is in the early
    stages of rusting.

    I have a one inch adjustable reamer you could borrow, but your frame is likely larger than that. I
    could see how far up it goes.

    I used it to remove rust and a weld blob inside a cheap frame. Got the post moving so smoothly,
    that with a spring, it wouldn't have been a bad suspension setup. But it wouldn't last. Aluminum
    on steel...

    There are tube cleaning brushes that work well with an electric drill. Get one with a long stem, and
    measure the ID to get a brush to fit. MSC at

    Oh, and go both directions when you do it, and go in and out in long strokes. And take out the bb
    first, or do the whole thing upside down. :) Not recommended.

    It gets real dirty.

    To seal the finished work, wrap with a little bundling wrap or Saran.

    what needs to be done, lie to it. Don't try this trick on people.
