Abstract

A multiple freewheel for a bicycle comprises a set of diametrically different sprockets axially fitted onto a sprocket ring or carrier which is rotatably supported on an inner ring via a one-way clutch. The sprocket set is preassembled by retainer pins each of which has an enlarged head engaging with an axially innermost sprocket of the set and penetrates through the set to project out from an axially outermost sprocket of the set in press-fit engagement therewith. A nut member is screwed on the sprocket ring to press the pin tip out of press-fit engagement with the outermost sprocket.
