ABSTRACT:
A multi-speed bicycle free wheel assembly comprises a free wheel body and a plurality of sprocket wheels different in diameter and fixedly mounted on the free wheel body, the free wheel body including an inner ring or driven member, an outer ring or drive member, a ratchet mechanism interposed between the two members for transmitting one way drive power to the outer ring, and a screw cup screwably secured to one side of the free wheel body, the screw cup having an annular flange formed integral with and extending circumferentially from a screw cup body, the annular flange extending parallel to and beyond the smallest sprocket wheel so as to prevent a bicycle drive chain from being accidentally disengaged outward from the smallest sprocket wheel disposed outmost relative to other larger sprocket wheels.
