Bicycle wheel some other fixed point may be used as a reference mark, however this is less accurate. At one end of each spoke is a specialized nut, called a nipple, which is used to connect the spoke to the rim and adjust the tension in the spoke. The nipple is usually located at the rim end of the spoke but on some wheels is at the hub end to move its weight closer to the axis of the wheel, reducing the moment of inertia. Until recently there were only two types of nipples: brass and aluminum (often referred to as "alloy").
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
