I want to lift the handlebars on my bike up a little bit because I'm uncomfortable with them this low. I tried loosening the bolt thing (I don't know the name of the parts) but there are two (the second one is on the other side that isn't pictured), one would come out and the other wouldn't. The one that wouldn't come out I am assuming is supposed to like, help keep the other one in. With only removing one, the handlebars won't move at all. If you know how to adjust the handlebars, I would appreciate some help.
