ABSTRACT:
A method of making a skate wheel is formed of a transparent, high strength rigid core having a high degree of clarity, which firmly secures and positions a pair of inner bearing races. A transparent wear resistant resilient wheel casing is injection molded completely around the core. The materials are chosen and molded so as to provide an entirely transparent wheel that exhibits the color of the core and in which a display imprinted upon the sides of the core is protected by the casing and made readily visible by light transmitted through both core and casing.
