Abstract: A bicycle chain connecting link comprises a link pin and a link plate. The link pin has a center axis and comprises a main-body, a head portion, and an intermediate portion. The intermediate portion has an outer diameter smaller than an outer diameter of the main-body and than an outer diameter of the head portion to define a groove between the main-body and the head portion. The link plate comprises an elongated opening to which the link pin is removably attached. The elongated opening comprises an insertion opening and an attachment opening connected with the insertion opening. The guiding portion includes a sliding surface slidable with the head portion. The protrusion is provided between the insertion opening and the attachment opening and protrudes from the sliding surface to be slidable with an outer periphery of the head portion.

Abstract: A bicycle chain comprises a first inner link plate. The first inner link plate comprises a first end portion, a second end portion, and a first intermediate portion. The first end portion includes a first opening, a first chamfered section, and a first chamfer-free section. The first chamfer-free section is provided in at least a first chamfer-free angular range when viewed from an axial direction parallel to a first center axis. The first chamfer-free angular range is defined from a first circumferential end of the first chamfered section to a first inner-link longitudinal centerline of the first inner link plate. The first chamfer-free angular range is equal to or greater than 30 degrees with respect to the first center axis.

Abstract: 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.

Abstract: A derailleur comprises a base member, a movable member, a linkage structure, a pulley assembly, and a rotational force control structure configured to control rotational force of the pulley assembly relative to the movable member. The pulley assembly is pivotally movable relative to the movable member about a pivot axis in first and second directions. The pulley assembly is configured to move in the first direction upon moving from a second pivotal position toward a first pivotal position. The rotational force control structure includes a cam member having a first cam surface, an abutment member configured to abut the first cam surface, and a biasing member configured to bias the abutment member. The abutment member is configured to abut the first cam surface by the biasing member to apply first additional force to the pulley assembly in the first direction while the pulley assembly is in the first pivotal position.

Abstract: A bicycle rear sprocket comprises a sprocket body, a plurality of sprocket teeth, a shifting facilitation recess, and an upshifting facilitation projection. The plurality of sprocket teeth extends radially outwardly from the sprocket body. The shifting facilitation recess is to facilitate a shifting operation in which a bicycle chain is shifted between the bicycle rear sprocket and a smaller rear sprocket adjacent to the bicycle rear sprocket without another sprocket between the bicycle rear sprocket and the smaller rear sprocket. The upshifting facilitation projection is provided in the shifting facilitation recess to support the bicycle chain in an upshifting operation in which the bicycle chain is shifted from the bicycle rear sprocket to the smaller rear sprocket.

Abstract: A bicycle sprocket includes 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 sprocket. The first side surface is a smaller sprocket facing side of the bicycle sprocket. 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 at least one shift assist tooth having a recessed portion recessed from the first side surface toward the second side surface. A protuberance is formed in the recessed portion.
