Abstract

La présente invention concerne un guidon sur lequel la localisation et la fonction d'une poignée varie en fonction de l'application de la bicyclette et de la posture du cycliste. Ce guidon de bicyclette comprend une barre de guidon (10) située au sommet d'une fourche avant (F) et des poignées (20) possédant des parties repliées (130) orientées vers l'avant d'une roue, des deux côtés de la barre de guidon (10), ces poignées (20) étant connectées aux parties repliées (30) de façon à tourner selon un angle donné. Chacune de ces poignées (20) comprend un tuyau (23) possédant un certain nombre de rainures (22a) et une projection courte (22b) formés sur sa circonférence extérieure, une unité de couplage de poignée (25) couplée de façon rotative au tuyau (23) de sorte que la rainure (22a) et la projection courte (22b) soient confinées dans l'unité de couplage de poignée (25), cette unité de couplage de poignée (25) étant couplée à la poignée (24) qui fait saillie vers le haut à partir de cette unité et une projection anti-rotation (25b) verrouillée à la projection courte (22b) est formée sur la circonférence intérieure de l'unité de couplage de poignée (25) et, une unité de limitation d'angle (26) qui sert à arrêter une unité de couplage de poignée (25) avec l'unité de couplage de poignées (25) tournée contre le tuyau (23) à un angle donné, ce tuyau (23), cette unité de couplage de poignée et cette unité de limitation d'angle (26) étant situés sur les deux côtés de la barre du guidon (10).
