• a casing;
• a lever moveable relative to the casing for actuating a gear change of a bicycle;
• and
• a rail arranged on the casing, wherein the rail extends between a first end and a second end, wherein the lever is configured to move along a length direction of the rail, which extends between the first end and the second end of the rail, for actuating the gear change of the bicycle,
• wherein the rail extends about a width direction, and wherein the rail projects from the casing about a height direction,
• wherein the casing comprises a flange located at the second end of the rail, wherein the flange is configured for inhibiting the lever to continue moving beyond the second end of the rail in a direction which extends away from both the first end and the second end of the rail,
• and wherein the flange:
• at least partially spans, and projects beyond, a first side of the rail,
• at least partially spans, and projects beyond, a second side of the rail, wherein the second side is opposite the first side, and
