• Servicing the headset on my Dart I've noticed some light surface rust on the inside inside of the head tube and can see it has crept into the top tube. Exploring further I found a little in the BB shell and I'm assuming there will be some in the sea tube and chain stays. I believe the tubing is a combination of Air and Spirit.

    The BB shell rust came off very easily with a wire brush and although the HT is a little more set in I think I can get the majority of it off. The seat, down and top tube will be harder to get to and the stays particularly tricky with a brush.

    Unless someone tells me different I don't think I need to be too worried about it (should I be?!) but I would like to stay on top of it and not let it get worse. What frame saver applications do people recommend and does anyone have a link to some long wire pipe brushes for getting down the tubing? Watching a tutorial on YouTube it was noted to avoid bb threads with frame saver, any reason? Also I'm assuming it would be a good idea to remove my alloy headset?

    Thanks.
