Abstract
Spoke wheels need to make spokes overhung to secure the stiffness of wheel. However the overhunged spokes would cause the air resistance. Therefore, in this study we suggested a racing bicycle wheel which have no overhunged spokes without reducing the stiffness of wheel. Concretely, we performed an optimum design of the racing bicycle wheel with the section radius of each spoke as design variable parameters and gross weight of the wheel as an objective function. Consequently, it was estimated that the optimized model on the section radius 2.3mm showed less deformed than existing racing bicycle spoke wheels. Finally, we maked a full-size model with the result of the optimum design.
