摘要： A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing in accordance with a permitted cadence range and a first threshold of the driving torque.

摘要： A bicycle derailleur comprises a base member, a movable member, a pulley assembly, a rotational-force adjustment structure, an electric actuator, and a controller. The rotational-force adjustment structure is at least partly disposed between the movable member and the pulley assembly so as to apply resistance to rotation of the pulley assembly relative to the movable member. The electric actuator is configured to operate the rotational-force adjustment structure. The controller is configured to control the electric actuator based on a driving-force related information.

摘要： A bicycle chain comprises a first outer link plate, a second outer link plate, and an axial protuberance protruding. The first outer link plate comprises a first end portion, a second end portion, and a first intermediate portion. The second outer link plate comprises a third end portion, a fourth end portion, and a second intermediate portion. The axial protuberance protrudes from a first inner surface of the first intermediate portion in an axial direction. The second intermediate portion of the second outer link plate is free from an axial protuberance protruding from a second inner surface of the second intermediate portion in an axial direction.

摘要： A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one chain-curvature limiting protuberance. The sprocket body is configured to be rotatable about a rotational center axis. The plurality of sprocket teeth extend radially outward from an outer periphery of the sprocket body. The at least one chain-curvature limiting protuberance is configured to limit axial curvature of a bicycle chain engaging with an independent neighboring bicycle sprocket which is adjacent to the bicycle sprocket without another sprocket between the bicycle sprocket and the independent neighboring bicycle sprocket. The axial curvature is curvature of the bicycle chain relative to the bicycle sprocket when viewed from a radial direction perpendicular to the rotational center axis. The at least one chain-curvature limiting protuberance is disposed on at least one of an outward facing side and an inward facing side.

摘要： A bicycle chain comprises a first outer link plate, a first inner link plate, and a first link pin. The first outer link plate comprises a first end portion, a second end portion, and a first intermediate portion. The first end portion includes a first opening having a first center axis. A first outer-link distance is defined from the first center axis to a first end edge. The first inner link plate comprises a third end portion, a fourth end portion, and a second intermediate portion. The third end portion includes a third opening having a third center axis. A first inner-link distance is defined from the third center axis to a third end edge. A second inner-link distance is defined from the third center axis to a third end edge. The first inner-link distance is larger than the second inner-link distance and the first outer-link distance.

摘要： A bicycle rear sprocket is basically provided with a sprocket body and a chain engagement structure. The sprocket body has a center rotational axis, a first side surface and a second side surface. The first and second side surfaces face oppositely with respect to an axial direction of the bicycle rear sprocket. The first side surface is a smaller sprocket facing side of the sprocket body. The chain engagement structure includes a plurality of sprocket teeth extending radially outward from an outer periphery of the sprocket body. The sprocket teeth include a first shift tooth and a second shift tooth. The second shift tooth is positioned at a third tooth position in a downstream direction of a rotational driving direction of the bicycle rear sprocket with respect to the first shift tooth. The first shift tooth and the second shift tooth function as a shift tooth when a bicycle chain moves from a smaller bicycle rear sprocket to the bicycle rear sprocket.
