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 ...
Bicycle parts. List of bicycle parts by alphabetic order: Axle: as in the generic definition, a rod that serves to attach a wheel to a bicycle and provides support for bearings on which the wheel rotates. Also sometimes used to describe suspension components, for example a swing arm pivot axle
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.
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.
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).
