ZINN AND THE ART OF BIKE MAINTENANCE. From basic repairs like how to fix a flat tire to advanced overhauls of drivetrains and brakes, Lennard Zinn’s clearly illustrated guide makes every bicycle repair and maintenance job easy for everyone. Lennard Zinn is the world’s leading expert on bike maintenance and repair. His friendly step-by-step guide explains the tools you’ll need and how to know you’ve done the job right. The book’s two-color interior is easy to read—even in a dimly-lit garage or workshop. Hundreds of hand-drawn illustrations and exploded parts diagrams show just the right level of detail to lead you through every bicycle repair task. I worked closely with Lennard to get each illustration correct to his high standards. He is a great guy, and a true pro. I have worked on both his road bike, and mountain bike books.
