Abstract
Bicycle hub includes a shell rotatably supported relative to a hub axle, a rotor rotatably supported by two rotor bearings, and a freewheel device having two interacting freewheel components: a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each include axial engagement elements and are axially movable relative to one another between a freewheel position and an engaging, driving torque position. The hub-side freewheel component includes a threaded axial body section and is screwed into the hub shell. The hub-side freewheel component has an axial, annular surface on which the axial engagement elements are configured. The rolling members of a hub bearing show a defined accommodation inside the hub-side freewheel component to support the shell relative to the hub axle. The hub-side freewheel component includes a tool contour which couples to an adapted tool for releasing the screw connection of the hub-side freewheel component with the shell.
