Background: I have no bicycle maintenance experience except for tightening brakes and installing racks. How hard is it to install a new stem? I have a new stem for my bike, is it pretty simple and easy to do just using youtube/explanations, or should I just take it to the LBS and have them do it? I have allen wrenches etc., I have no idea what is needed or how to do it, although intuitively it seems like just taking the other stem out, taking the handlebars out, attaching them to the new stem, putting the new stem in and tightening it.
