Hub, in particular for bicycles

A hub for at least partially muscle-powered vehicles comprising:

• a hub axle;
• a hub shell;
• a threaded ring;
• a rotor;
• and a freewheel device;
• wherein the freewheel device comprises a hub-side toothed disk device and a rotor-side toothed disk device interacting therewith, each comprising an end toothing for engagement with one another, and biased to an engagement position by means of at least one biasing device,
• wherein the threaded ring has an outer contour with an external thread, and a central through hole with an inner contour, wherein the inner contour is configured with a non-round inner coupling contour, which couples, in a rotationally fixed manner in a driving direction, with a matching non-round outer coupling contour on the outer periphery of the hub-side toothed disk device;
• and
• the threaded ring has a central depression at the rotor-side end, so that the external thread on the threaded ring extends in a direction to the rotor axially further outwardly than does the inner coupling contour, so as to widen the external thread of the threaded ring in the direction toward the rotor.
