Tandem bicycle stem that is clamped around the captain's seatpost. The stoker handlebars are typically bullhorns or drop bars with "dummy levers" instead of brake levers for gripping. Because of the extra weight and stresses, tandem wheels may use a higher spoke count, sturdier rims, higher pressure tires, a stronger freewheel, dishless spoke configuration, or asymmetric wheels. Tandems wear out rear wheels faster than front wheels; therefore, they may use non-symmetrical wheel setups, such as more spokes or a sturdier rim on the rear wheel. The dish of a wheel measures the amount of asymmetry between the rim and the hub flanges.
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
