LOL! Don't!! I'm amazed at how much they don't tell newbies and think bike shops should be more newbie friendly! I wish all bike shops offered courses where they taught newbies classes on how to do a lot of basic maintenance, etc. I got the lesson "watch me" lesson on how to change my tube in case of a flat, but have yet to have a flat. Now I'm wondering over a year and a half later, if I remember a thing they told me. I prefer to learn by practicing and wish the shops offered classes to give me practical experience.
