The radial, lateral, and tangential stiffness of spoked bicycle wheels relies upon the rim's bending inertia, torsional inertia, spoke sizes, and spoke geometry. The spokes of three rear bicycle wheels with different spoke patterns were equipped with strain gauges to study the effect of the spoke pattern on the spoke strain and fatigue resistance properties of the wheels. In the laboratory, spoke strains due to radial loads were measured. Time records of the strain of a right pulling spoke were gathered from each of the wheels under actual riding conditions. Analytical, numerical, laboratory, and field studies revealed that spoke strains due to radial loads and in service conditions are not sensitive to spoke pattern. Small differences in the spoke strains between the wheels in the road tests can be attributed to load variations, but do not significantly affect the fatigue life of the wheels.
