Technical issues, such as hardening (difficult to activate) and shrinking (causing the horn to sound without activation) of the rubber, and a lack
The Bicycle Wheel The Bicycle Wheel The Bicycle Wheel is a treatise on wheelbuilding by Jobst Brandt. "The Bicycle Wheel" is an educational book that explains the structural theory of a wire wheel, and teaches the practical methodology of building bicycle wheels. The book is made up of three parts. Part one, 'Theory of the Spoked Wheel', examines how a wire wheel supports various loads, what causes wheel failure, what aspects of a wheel confer strength and durability, discusses each of the individual components that make up a spoked wheel, and examines wheel design. Part two, 'Building and Repairing Wheels', explains how to
