The invention concerns a motor actuated derailleur (1) for a bicycle gearshift, comprising:
- a support body (102) suitable for being mounted on a bicycle frame,
- a chain guide (103) suitable for moving a bicycle chain between different engaged positions on respective gear wheels,
- a pair of connecting rods (104, 105) that connect said chain guide (103) to said support body (102) in a mobile manner, a first connecting rod (104) of said pair of connecting rods (104, 105) being rotatable about a first rotation axis (X) at a first end (104a) thereof,
- a gear motor unit (10), housed in said support body (102) and provided with an output shaft (13) able to rotate about a second rotation axis (Y),
- a motion transmission (14, 104b) between said gear motor unit (10) and said first connecting rod (104), housed in an inner chamber (102a) of said support body (102),
in which said inner chamber (102a) comprises at least one adjustable end stop element (20, 220) that prevents the rotation of the output shaft (13) beyond a certain rotation angle, in at least one of the two directions of rotation of the output shaft (13). |
