Bicycle wheel metal or carbon fiber rim which holds a pneumatic rubber tire. A hub is the center part of a bicycle wheel. It consists of an axle, bearings and a hub shell. The hub shell typically has two machined metal flanges to which spokes can be attached. Hub shells can be one-piece with press-in cartridge or free bearings or, in the case of older designs, the flanges may be affixed to a separate hub shell. The axle is attached to dropouts on the fork or the frame. The axle can attach using a: Modern bicycles have adopted standard axle spacing: the
The Bicycle Wheel select components, how to build a wheel, and how to repair various forms of damage. Part three, 'Equations and Tests', provides a mathematical analysis of spoked wheels. "The Bicycle Wheel" is considered by many to be the premier resource on building bicycle wheels. Noted bicycle mechanic and technical expert Sheldon Brown called it "the near-definitive text on the theory and practice of building spoked bicycle wheels." 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
