The hub spindle (1) consists of two parts (17, 23) axially disengageably coupled with one another. The first part is independently securable to the frame (15) of the cycle, and a drive member (5) is rotatably mounted thereon. On the second spindle part (23) a hub sleeve (3) is mounted by ball bearings (51, 53). A pawl freewheel (13) with radial pawls (73) mounted in the hub sleeve (3) couples the drive member (5) with the hub sleeve. A stop (81) formed preferably by the outer race ring (57) of the adjacent ball bearing (53) holds the pawls (73) approximately in the position determined by a pawl toothing (79) of the drive member (5), even when the hub sleeve (3) is removed. The hub sleeve (3) can be removed from the drive member (5) and fitted on to it again without problem after the removal of the insertable second spindle part (23). The hub sleeve and spacer (71) are clamped in position by a cap (43) cooperable with eccentrics (41) on a pin having a hand lever (45). <IMAGE> |
