Bicycle shift control device

摘要

The device has a rotatable unit (60) coupled to a fixed unit (22) between two shift positions. The fixed unit and rotatable unit include a visible fixed contoured line (46) and a visible movable contoured line (70), respectively. The lines cooperate with each other to define a geometrically shaped area (G), which changes upon rotation of the rotation unit between the shift positions to indicate one shift position.
