US Patent 11932351 Conical bicycle cassette sprocket structure

A conical shaped bicycle cassette has a unitary sprocket assembly. Each annular portion of an individual sprocket is mechanically supported either from a back of the sprocket, in an axial direction toward a bicycle hub or from an inner radial direction toward a centerline axis of the bicycle cassette and hub. The axial support zones and radial support zones are alternated around a circumference of the sprocket so that an entirety of the sprocket is supported in either the axial direction or the radial direction. In this way, the chain driving loads on the cassette are spread throughout the entire cassette and the areas of highly localized stress from the cassette are removed.
