A device (42, 50, 70, 75, 80, 85) for manually inputting commands for an electronically servo-assisted bicycle gearshift (8) comprises a lever (54, 86) configured to actuate a first switch (60) when it is rotated by a first predetermined angle, and to actuate the first switch (60) and a second switch (61) when it is rotated by a second predetermined angle after the rotation by the first predetermined angle. A command input requesting gearshifting in a first direction is considered to be valid when only the first switch (60) is actuated, and a command input requesting gearshifting in a second direction is considered to be valid only when both of the switches (60, 61) are actuated. |
