The fixture stirrup (1) is placed around the rear axle (2) of a bicycle, and has a shaped part (5) on which a ball-shaped hinge part (7) is fitted via a rod-shaped component (8). Both the hinge part and the rod-shaped component are tapped and through the tap a bolt (9) is inserted, provided with a self-tapping nut (10). In the fixture stirrup is formed a relatively large aperture (11), through which the rear axle extends, through which a part of an axle location (12) of the frame (4) is visible. The aperture is provided with internal teeth (13). An auxiliary piece (14) is fitted around the axle, successively provided with a collar (15), external teeth (16) and a projection (17). |
