Abstract:
A bicycle transmission includes an axle, an input component, a power transmission mechanism, a shift mechanism and an output component. The input component receives manually applied rotational force. The output component is rotatably supported by the axle. The power transmission mechanism transmits the rotational force of the input component to the output component through one of a plurality of power transmission paths. The shift mechanism includes a shift input member, a shift control member, a first saver spring and a second saver spring. The shift input member is settable in a plurality of rotational positions. The shift control member rotates in conjunction with movement of the shift input member to select one of the power transmission paths. In the shift mechanism, as the shift input member rotates in the first direction, the shift control member receives the rotational force applied in a first direction through the first saver spring.
