Hello there. I'm new to cycling, but I've been having a blast with my new 2012 Trek 8.3 DS. Yesterday, I had my first flat and unfortunately, it was the rear tire. I had no idea how to remove the tire and gears so I had to take it to my local bike shop for repair. I'm wondering whether anyone can suggest a comprehensive and visually instructive book regarding routine bike maintenance and general "how-to" information? I think it would be a great help and better than running to Google for everything.
