Takes a standard english/japanese threaded bb.

standard 1" fork. There is an extender in the fork steerer tube that the quick release stem clamps on to. You will see a 6mm bolt down inside that holds the extender in place. Leave the stem on for leverage, loosen the recessed extender bolt about a quarter of in inch high, tap on your allen wrench since the bolt is recessed. That should loosen the wedge and it will lift out. If its rusty, shoot some wd-40 in there before you start. Clean the inside of the steerer tube, put some grease in there to prevent future rust. A normal quill stem can be installed.

Steel frames can be respaced pretty easy. 2.5 mm on each side isn't much but it beats trying to wrestle your wheel in & out each time. Sheldon Brown has a web page on doing just this on steel frames. Also use the string method to measure progress and to make sure it's even. Don't just bend one side out 5 mm, do each side 2.5 mm to keep the wheels tracking straight. I've done many steel frames, forget it on aluminum, ti or carbon.
