A drive hub for a bicycle has a driving member with a plurality of annular members positioned on an outer peripheral face of the driving member. A mounting sleeve is used for facilitating the assembling of the hub. This mounting sleeve is provided on its outer peripheral face with an angular positioning profile substantially identical with the torque transmitting profile of the driving member. First and second axial abutment members are provided on the outer peripheral face of the mounting sleeve adjacent a first and a second axial end of the mounting sleeve. Centering tongues and counter centering grooves are provided on one axial end of the mounting sleeve and on the driving member, respectively. When these centering elements are brought into engagement, the angular positioning profile of the mounting sleeve is both in axial and angular alignment with the torque transmitting profile of the driving member. So the annular members which have been pre-assembled before on the mounting sleeve between the first and the second abutment members may be axially slid onto the driving member while the first abutment members are deflected by the annular members sliding from the mounting sleeve onto said driving member. |
