I hope this isn't a stupid question, but do most of you do this yourself? I've had my bike for a few months, and yesterday as I was riding, I seemed to be slipping out of gear. Very annoying. And alarming on hills, too!

Should I just bring the bike in to the shop? I know directions are out there online, but I'm not mechanically inclined, and I don't know anything, really, about bike mechanics. I can change a tire and clean and lube a chain, but that's pretty much it!

Perhaps I need to take a clinic or something at the LBS.
