Abstract
Cette fixation pour guidons de bicyclettes comprend une potence adaptée à une extrémité pour s'accoupler à un tube de tête C et présentant à son extrémité opposée un oeil pour recevoir le guidon. L'oeil est divisé par une fente 4 en deux mâchoires dont l'une 5 présente un trou borgne fileté 7 et dont l'autre présente un trou traversant 8 fileté, dans l'alignement du trou borgne, pour recevoir une vis 10 qui sert à resserrer les mâchoires l'une contre l'autre pour resserrer l'oeil sur le guidon. Lorsqu'on a dévissé la vis du trou borgne, on peut insérer une plaquette de butée 11 dans la fente puis serrer la vis contre cette plaquette pour écarter les mâchoires à force et permettre d'enfiler le guidon dans l'oeil ou de l'en dégager.
