Default Trek Steerer tube size

I am considering replacing the threaded headset system of my '2001 2200. I
hear there's about a pound to save and better handling too. I know I need to
replace the current carbon fiber icon fork for a new threadless model but I
don't know what diameter steerer tube I need. Anyone know, and what
forks/headsets do you recommend?

The same diameter as your existing threaded one. The only possibilities
are 1", 1 1/8" or (incredibly rare) 1 1/4".

The handling won't change unless you buy a fork with a different length or
offset than your present one. You'll also be lucky to save a pound just by
going threadless, unless your current parts are unusually heavy.

It's a 1".

How much do you want to spend?

Maybe 7 or 8 ounces, but I doubt that you'll save a pound unless the
existing stem's a boat anchor. As for handling, there should be zero
difference. The principal change will be that if you trim the
threadless steerer to the minimum length useful for your setup, you
will no longer have a method of adjusting bar height without swapping
to a different stem. If you leave the steerer uncut and add spacers,
you can move the stem up and dpwn a little, but not as much as is
typically possible with a conventional quill. (You commented that
you're looking at a carbon fork; if it has a carbon steerer, that
limits the amount of spacers permitted.)

Before you go any farther, I suggest a stop by your local bike shop to
check availability and price of all of the various items you'll need.
It would be wise to have them fit the fork and headset so that you
have some assurance that the lower bearing is correctly seated and
that the tube is cut properly.
