|Is changing a threadless stem as easy as a quill? Do I just unscrew the bolt on top, or are there a bunch of small pieces that would preclude a lame-o like me from doing it?

|Lots of quills didn't have removable faceplates, so you had to remove a shifter.
Nearly all threadless has a removable faceplate. Its easy. The only thing that makes it easier is to have a buddy hold the bars up when you install the new stem.
Remember the top cap screw only sets the bearing preload. The stem bolts actually secure the stem to the steer tube.
And remember the grease, if applicable. And don't forget to use a torque wrench!!!

|This is cake...you can easily do this on your own.
1. Take off the top cap.
2. Then unscrew the stem. (this will free the fork so be aware if you bike is on a stand, I like to remove my front wheel first)
3. Swap the stem. (don't tighten stem yet)
4. Install Cap. (note: at this point you might need more or less spacers to have cap work correctly.) This cap is how you control the pressure on the bearings, so tighten untill there is no longer play in the headset.
5. once you have got the play out, tighten the stem bolts and done.
Problems you might run into...changes in stack height of new stem causing a need for more or less spacers...droping the fork to the floor and lossing part to the head set...a carbon steer tub needs special attention, mainly just don't get stem too tight and don't use spider type binder nut.
