ABSTRACT:
A shifting apparatus for a bicycle includes a fixed shaft, a takeup element rotatable about an axis of the fixed shaft to wind a control cable thereon, a shift lever for rotating the takeup element, and an indicator. The indicator includes a rotatable member interlocked to the takeup element to be rotatable about a rotational axis, and a fixed member for a speed stage of a change gear device based on a displacement relative to the rotatable member. The rotational axis of the rotatable member extends at an angle to the axis of the fixed shaft. At least a portion of the indicator is present on an extension of the axis of the fixed shaft.
