    How do you flip stems on threadless steerers?

    Just turn it over. The logo will be upside down when flipped. Some stem makers have their logo right
    side up on one side and upside down on the other just for this purpose.

    If this is a lot of work, take it off the bike first. :)

    if you are new to bikes:

    yes, you just flip it over. but before you do this, unscrew the bolt holding the cap onto the stem.
    usually a 5mm allen. take the bolt and cap off. then unscrew the bolts in hte stem. while you do
    this, hold on to the fork or it will just fall out the bottom of the steerer. when it is loose flip
    it over, put the cap and bolt back in, and screw down the cap just enough so that you dont feel any
    play at all in the fork/headtube. feel for this easily by putting the front brake on and rocking the
    bike on the floor, or by whatever means you feel best with. you should not feel any grating, and the
    headset should feel as smooth as it did before. then, and only then, you tighten the stem bolts.

    cheers

    Also check if the cables and housing are still long enough. Front and rear brake.

    Secure the fork to the bicycle*. Remove top cap. Unscrew stem fasteners. Remove stem. Reinstall stem
    with the other side up. Install handlebars, lubricate and tighten handlebar fasteners.Install top
    cap. Lubricate and screw the top cap screw gently tighter until headset play is taken up**.
    Lubricate and secure stem fasteners.

    *If you work on bicycles in midair, the first time you remove an AheadSet stem there's a high risk
    of puncturing your foot when the fork slams through
    it. Ouch.

    **Even those who work in midair finish two things on the floor. One is headset bearing adjustment,
    which can be evaluated best with the front brake applied and the bicycle rocking front to back. The
    other is saddle angle. Hard to get 'em level without the bike on the floor.
