This invention relates to bicycle hub nuts which, however, according to the invention, are of a mushroom-shaped construction, have a non-slip knurling on the outside and have reflector discs and the like in their interior. These reflecting knurled mushroom nuts have no sharp edges and make it unneccessary to carry a (heavy) screwdriver or to attach spoke reflectors which, as a result of the rotation, produce an increased air resistance.
