A freewheel hub device includes two locking rings with axial grooves formed in the locking rings and being essentially V shaped in cross-section. The groove walls of one locking ring form a first and a second wedge surface, and one groove wall of the other locking ring forms a third wedge surface. A roll holder with rolls, which extend into the grooves of the locking rings, is mounted in the locking rings. A hub is rotationally arranged in the roll holder ( 14 ) and has a circumferential surface for cooperation with the rolls. The locking rings and the roll holder are turnable relative to each other in a limited manner and can take three different setting positions relative to each other.
