Streamlined wheel for bicycle

A streamlined wheel upon which a tire of a bicycle is mounted, the wheel comprising:

• first and second half-shells which when joined form a hollow wheel;
• each half-shell being made of reinforced composite plastic material, being circular about an axis and having a thin cross section;
• the half-shells each having identical, continuously convex curved outer surfaces terminating in rim portions extending inward of the convex outer surfaces, each rim portion being formed by a radial flange extending radially inwardly toward the axis and joined to the continuously convex outer surface by a peripheral portion and by an axial flange extending in the axial direction from the radial flange;
• means for joining the axial flanges of the half-shells to one another at a location on each axial flange spaced from the radial flange of the other half-shell to form a groove around the periphery of the wheel for receiving the tire, which tire forms a substantially continuous curve with the continuously convex outer surfaces.
