You ordered a good one in Joe Friel's "Cycling Past 50". I read mine a lot still. A good maintenance manual such as Lenard Zinn's "Zen and the Art of Road Bicycle Maintenance", Park Tool's "Big Blue Book" and some others are useful to learn how to do the things you need to underatand in order to keep your bike running smoothly. the people here will chime in with their favorites soon and you can build a helpful library with their suggestions.
