Conventional metallic bicycle wheels have 24, 28, 32 or 36 spokes. Wheels on tandems and BMX often have 40 or 48 spokes to support additional stresses and weight. Lowrider bicycles may have as many as 144 spokes per wheel. [20] [21] [22] Wheels with fewer spokes have an aerodynamic advantage, as the drag is reduced. The reduced number of spokes ...
Skirt guard or coatguard: a device fitted over the rear wheel of a bicycle to prevent a long skirt, coat or other trailing clothes or luggage from catching in the wheel, or in the gap between the rim and the brakes; Spindle: an axle around which a pedal rotates; threaded at one end to screw into crank arms; Spoke: connects wheel rim to hub ...
Commonly used models vary from 18 spokes for racing bikes to 36 for cross-country touring bikes to 48 spokes on tandems and heavily abused BMX bikes. The minimum number of spokes allowed for competition is 12. [1] Some lowrider bicycles use as many as 144 brightly chromed spokes per wheel, although these are not meant for serious riding.
A spoke nipple holds a bicycle wheel's rim to each spoke. The spoke nipple is a headed cylinder with threading on the inside through part of its length (there is an unthreaded lead-in nearest the "flats"). Traditionally, the nipples fit in holes in the rim, so that the head of the nipple is on the outermost part of the rim, while the other end ...
Tensioned spokes are usually attached to the rim or sometimes the hub with a spoke nipple. The other end is commonly peened into a disk or uncommonly bent into a "Z" to keep it from pulling through its hole in the hub. The bent version has the advantage of replacing a broken spoke in a rear bicycle wheel without having to remove the rear gears.
Bicycle manufacturers build millions of wheels annually, using the common crossed-spoke patterns whose crossings of adjacent spokes are governed by the number of spokes in the wheel. Wheelbuilders of racing teams and in good bicycle shops build wheels to other patterns such as two-cross, one-cross, or no-cross (usually called radial).
