One Gear is a unique, much needed contribution to the culture that explains in simple, easy to understand language the steps required for a beginning or intermediate bike mechanic to learn how to rebuild and convert a geared bicycle into a slick, personalized fixie or single-speed. One Gear also contains chapters on single-speed variants such as flip-flop hubs, torpedo hubs and modern coaster brakes, as well as pictorial essays featuring frame builders ranging from classic standard bearers such as Cinelli and De Rosa to contemporary practitioners like Icarus Frames.
