Abstract
L'invention concerne un dérailleur avant utilisé pour faire passer une chaîne d'entraînement d'un pignon à l'autre parmi deux pignons. Selon l'invention, il comprend un organe de fixation 9, un guide-chaîne 10 supporté sur l'organe de fixation, et qui est axialement mobile par rapport à chaque pignon et par rapport à l'organe de fixation, et vers au moins deux positions correspondant à chaque pignon, et il sert à faire passer la chaîne d'entraînement de l'un à l'autre des pignons, un moyen d'ajustement 11 de la position du guide-chaîne 10 par rapport à l'organe 9, avec un moyen de soutien 12 pour maintenir la position ajustée du guide-chaîne par rapport à l'organe de fixation. L'invention s'applique notamment aux bicyclettes.
