ABSTRACT:
The bicycle gear mechanism, in particular a rear wheel change mechanism, comprises a derailleur provided with a drive chain guide element. The derailleur comprises: an arm (2); a first attachment element (5), rotatingly constrained to the arm (2) by a first shaft (3), the first attachment element (5) being predisposed to connect the arm (2) to the bicycle frame; a second attachment element (6), rotatably constrained to the arm (2), the second attachment element (6) being predisposed to connect the arm (2) to an element (7) predisposed to guide the drive chain (30) of the bicycle; a mechanism predisposed to rotatingly connect the first shaft (3) and the second shaft (4); at least an actuator, operatively connected to the arm (2) and the bicycle frame, which actuator is predisposed to rotate the arm (2) about the first shaft (3).
