ABSTRACT:
A bicycle wheel includes a rim, a spindle and a hub articulately mounted on the spindle. A first pair of sections with opposite-hand threads are located symmetrically on the middle portion of the hub. A second pair of sections having opposite-hand threads of less diameter than those of the first sections is located on the hub at the end of the hub. Adjacent threads between the first and second sections are opposed in direction, and carry first and second flanges respectively. Situated on opposite sides of the hub are reinforced composite material diaphragms, shaped as an annulus, and interposed between the first and second flanges. The diaphragms are rigidly coupled with their inner side to the first and second flanges, and with their outer side to the rim.
