Spoke tangentially to the hub. Tangential spoking allows for the transfer of torque between the rim and the hub. Tangential spokes are thus necessary for the drive wheel, which has torque at the hub from pedalling, and any wheels using hub-mounted brakes such as disk or band brakes, which transfer torque from the rim to the brake in the opposite direction—(via the hub) when braking. Constructing a tension-spoked wheel from its constituent parts is called wheelbuilding and requires the correct building procedure for a strong and long-lasting end product. Tensioned spokes are usually attached to the rim or sometimes the hub
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
