switched out the handlebars!

[DebW]

First I learned that you can't get the handlebars off by loosening the nut that attachs them to the stem.

Then I learned that you can't get the stem out of the headtube by loosening the rather large nut there.

Then I learned that when you have a threaded stem, you don't need to unscrew the thing all the way, because the little piece at the bottom falls out..

Tools to remove a quill stem include a wrench and a hammer (for tapping the stem bolt if it sticks up after you loosen it). What did you learn about rubber handlebar grips?
