Abstract

【Item Uses】 This design relates to a bicycle part, specifically a one-piece molded bottom bracket cup. 【Design Description】 Please refer to the drawings. The dotted lines in the drawings represent the parts that are not recommended for design in this case. The main feature of this design is that the five-way bowl is made in one piece, making both ends of the bowl concentric along the axis, thus combining practicality and visual recognizability. The five-way bowl is a symmetrical cylinder, therefore the rear view, top view, and bottom view are omitted in the drawings.
