So on another thread I was having trouble getting my new handlebars through my stem (finally got that fixed, so thanks all who helped) and someone suggested removing the stem as a way to help (I was thinking about removing the stem anyway just to get one with a removable faceplate as the bars were stuck in at the time and I couldn't move them forward or backward - also it's a bit rusty), so I tried to take it out. It's a quill stem. So anyway, I removed that long ass bolt from the top of it and loosened that collar or whatever you call it that goes around where the stem comes out of the top of the frame and couldn't get the thing to budge. Is there something else I'm missing that I needed to loosen to get it out of there, or is it possible that what I thought was just superficial rust on the stem has continued below and allowed the thing to freeze in place. If so, how to I go about getting it out? Or am I just stuck with it?
