Abstract
A hub for bicycles includes a hub shell which is rotatably supported relative to a hub axle by two roller bearings disposed on opposite ends of the hub shell, a rotor rotatably supported relative to the hub axle by two rotor bearings, and a freewheel device having an interacting hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each have axial engagement elements and are axially movable relative to one another between a freewheel position and an intermeshing engaging position. The rotor is disposed in the same axial position both in the freewheel position and in the engaging position. A driving torque is transmitted in the engaging position. The hub-side freewheel component has an inner central receiving space with a bearing seat and a roller bearing received to rotatably support the hub shell. The hub-side freewheel component includes an appendix protruding outwardly from the axial body section.
