Chacun des bras (22, 23, 24) présente au moins un élément mobile (32a, 33a, 34a) qui peut se déplacer dans la direction radiale. Une griffe (12, 13, 14) amovible est placée sur chacun des éléments mobiles (32a, 33a, 34a), cette griffe étant conçue pour venir en contact avec la bande de roulement de la roue (1) lorsque le support de roue (2) est monté sur une roue (1). Au moins une des griffes (12, 13, 14) peut être placée dans au moins deux orientations différentes sur au moins un des éléments mobiles (32a, 33a, 34a).
