More Information
Summary:The invention relates to a torque transmission assembly (9) for a bicycle. The torque transmission assembly (9) comprises an adapter device (13) and at least one driving body (12) that is rigidly connectable to the adapter device (13) in a torque transmitting manner. The adapter device (13) has at least three support arms (14) that extend with a radial direction component (23), and the driving body (12) has a corresponding number of support cutouts (15). The support arms (14) are able to be received in the support cutouts (15), in each case forming a press fit. The torque transmission assembly (9) is characterized in that the press fit of the support arms (14) and support cutouts (15) has two fitting planes (18, 22), which are parallel to one another and to an imaginary plane containing the axis of rotation (19) of the assembly (9). In this case, there is a clearance (25) between the support arm (14) and support cutout (15) along the radial direction component (23).
