Removing a tight stem
Old ID
Symptoms
The stem on my new Bike Friday can sometimes be difficult to remove. Any tips?
Causes
The connection between the steerer tube and the stem collar can be a bit tight when the bike is new. As the stem is removed and inserted over and over, the two surfaces will wear together and the stem will become easier to remove.
Be sure to liberally grease the part of the stem riser that slides into the steerer tube before reinserting. We recommend cleaning and replacing the lubrication on the stem riser annually.
Solutions
A simple trick to aid in the removal of a stem is to use your Bike Friday headset/pedal wrench between the headset top nut and the quick release at the base of the stem. Pry lightly up as you pull upward on the stem. See the attached diagram.
It can also help to keep a layer of grease between the steerer tube and stem collar.

I like this method a little better than the prying technique because there is less chance to chip paint or slip and scratch the paint, although it is a little slower. Just carry a screw (or you can ditch the QR for the screw like I did) and insert it on the threaded side of the bracket. Slide a coin in the space and as the screw begins to press the coin against the other side of the bracket (only a small amount of pressure is needed), it creates the slightest spreading effect and the stem riser slides right out. You can leave the screw and coin the way they are for quick reassembly when it is time to ride again.
