How to Rock and Roll: a City Rider's Repair Manual

This is exactly what the name implies. A bicycle repair manual for people who commute on their bikes. I've been waiting for a resource like this for years. It takes you step by step through every process of bicycle maintenance with pictures too! Includes stuff on frames, wheels, brakes, drivetrains, overhauls, safety checks, accesories, and more. This is thorough and bound to teach something to the most educated cyclist.
