I have a kestrel fork w/ a 1" threaded steerer. Is it possible to shorten the steerer tube and cut new threads into the fork steerer. I am not sure on the thickness of the steel throughout the tube. I am assuming the thickness is the same the length of the steerer and this would not compromise the fork steerer. thanks, Andy

Most good LBS's have the die to do this, and it is commonly done if the steerer tube is steel.
The steerer tube is beefy tubing (typically 1 - 1.1 mm) all along its length because it has to handle the internal expander from a 1" stem, anywhere inside the tube, and this is the more strenuous load on the steerer tube.

Sorry, most steerers are butted and thicker at the crown than at the top. Shorten the sttere too much and the quill of the stem won't insert far enough. Phil Brown
Mea Culpa !! I was looking at steerer tubes on Nova Cycles yesterday, but I must have gotten steerer tubes mixed up with head tubes (which are the tubes that are typically 1.0 mm and not butted, steerer tubes indeed are typically 1.6mm or thicker, and they are butted, viz :

It's done the other way around; first you extend the existing threads, then you shorten the tube. This is *far* more reliable than cutting first.

While I've heard tales of wierd butted steer tubes, I have yet to actually see one. You should be safe.

Butting at the bottom is common, yes, but I was told a tale of woe concerning a goofy steerer that was butted at both ends; when the threading was extended, it got really thin and twisted off. I don't recall what kind of fork it was, but the guy who had encountered it said he'd never seen another one like it, so it's rare enough that this should not be an issue. -- Typoes are a feature, not a bug.
