Cycling Science tours readers through a wide variety of topics, from tire rolling resistance and the difference between yield strength and ultimate strength, to the importance of aerodynamics and the impact that shaved legs have on speed. Each chapter explores a different subject-fundamentals, strength and stability, materials, power, aerodynamics, and the human factor-and is organized around a series of questions: What is the ideal frame shape? What is the biggest source of drag? What keeps a bicycle from falling over? How much power can a cyclist produce? Which muscles does cycling use? Each question is examined with the aid of explanatory diagrams and illustrations, and the book can be used to search for particular topics, or read through for a comprehensive overview of how machine and rider work together.

Athletes have much to gain from understanding the science of their sports, and Cycling Science will be a must-read for cyclists of all stripes-professionals, recreational riders, and anyone seeking to enhance their enjoyment of cycling.
