Wrong, wrong, wrong! For a quill stem-the type shown in photo. You do not want to unscrew the the headset nut-the large nut at the top of the headtube where the stem comes out. That large nut holds the headset bearings in place and has nothing to do with stem height. What you want to do its loosen the singel allen bolt at the top of the stem 2 turns then gently tap it downward with a hammer. This will loosen the wedge at the bottom of the stem that holds it to the forks steerer tube. Then you can raise or lower it, and then retighten the allen bolt. Three.very important details to remember: 1. Do not overtighten that allen bolt-it can damage the steerer tube. Check that it is tight enough by standing in front of bike holding front wheel between your legs and giving the bars a good strong turn. The wheel and bars should move together-if it slips, tighten bolt up a bit more. 2.Do not raise your stem past the minimum insertion line. This line is on the stem where it inserts into the fork steerer tube. If you see it, you are to high. 3. This is a quill stem, but many stems now are the aheadset type and are installed and adjusted completely differently. You must be clear about which type is which and what you are doing, or else your stem could pop of while riding-which could could cause serious injury or even be fatal. Take it to a shop if you are not absolutely clear about what you are doing-I've seen too many people muck about with these thing and no idea they were doing it completely wrong.
