    Abstract: A rear sprocket comprises a sprocket body, a plurality of sprocket teeth, a plurality of spline teeth, a maximum spline distance, and a radial tooth-bottom distance. Each of the plurality of spline teeth has a spline crest. The maximum spline distance is defined from the rotational center axis to the spline crest. The radial tooth-bottom distance is defined from a rotational center axis to one of plurality of tooth bottom center points. The maximum spline distance is larger than the radial tooth-bottom distance. The spline crest of each of the plurality of spline teeth is positioned radially inwardly from the tooth outline of each of the plurality of sprocket teeth in the radial direction.

    Abstract: A bracket apparatus for mounting a derailleur to a frame of a human-powered vehicle comprises a bracket body and one of a restriction member and a restriction opening. The bracket body includes a frame attachment portion configured to be attached to the frame of the human-powered vehicle and a derailleur attachment portion to which the derailleur is to be attached. The restriction member is configured to be at least partly provided in the restriction opening to restrict a rotation of the bracket body relative to the frame of the human-powered vehicle in a bracket mounting state where the bracket apparatus is mounted to the frame of the human-powered vehicle.

    Abstract: A bicycle rear sprocket assembly comprises a plurality of sprockets and a sprocket carrier. The plurality of sprockets includes a first sprocket and a second sprocket. The first sprocket has at least one circumferential coupling point. The first sprocket is coupled to a radially extending surface of at least one of a plurality of sprocket mounting portions at the at least one circumferential coupling point. The second sprocket has at least one additional circumferential coupling point. The second sprocket is coupled, at the at least one additional circumferential coupling point, to at least one of the sprocket carrier and one of the plurality of sprockets. A total number of the at least one circumferential coupling point is different from a total number of the at least one additional circumferential coupling point.

    Abstract: A bicycle hub assembly comprises a sprocket support body. The sprocket support body includes at least ten external spline teeth, a base support, and a larger-diameter part. The at least ten external spline teeth are configured to engage with a bicycle rear sprocket assembly. The at least ten external spline teeth radially outwardly extend from the base support. The larger-diameter part extends radially outwardly from the base support. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

    Abstract: A bicycle rear sprocket comprises a sprocket body, a plurality of sprocket teeth, an opening, and a torque-transmitting structure. The plurality of sprocket teeth extends radially outwardly from the sprocket body with respect to a rotational center axis of the bicycle rear sprocket. The opening has a minimum diameter that is smaller than a minimum outer diameter of a sprocket support body of a bicycle rear hub assembly. The torque-transmitting structure includes at least ten torque-transmitting teeth configured to directly or indirectly transmit a pedaling torque to the sprocket support body of the bicycle rear hub assembly.

    Abstract: A rear sprocket assembly comprises a first sprocket and a lock device. The lock device includes a first lock member and a second lock member. The first lock member includes a first axial end and a second axial end. The second lock member includes a third axial end and a fourth axial end. The third axial end is configured to be attached to the second axial end of the first lock member in an assembled state where the first sprocket and the lock device are assembled as one unit. The fourth axial end has at least one radial projection configured to abut against a first sprocket in the axial direction in the mounting state. The lock device is configured so that the first sprocket is slidable relative to the lock device in the axial direction in the assembled state and before the mounting state.

    Abstract: A bicycle hub assembly comprises a hub axle, a hub body, and a sprocket support body. The hub body includes a first spoke-mounting portion, a second spoke-mounting portion, and a first axial length. The first axial length is defined between a first axially outermost part of the first spoke-mounting portion and a second axially outermost part of the second spoke-mounting portion in an axial direction and is equal to or larger than 55 mm. The sprocket support body includes a plurality of external spline teeth. The plurality of external spline teeth includes a plurality of external-spline driving surfaces. The plurality of external-spline driving surfaces each includes a radial length defined from a radially outermost edge to a radially innermost edge. A total of the radial lengths of the plurality of external-spline driving surfaces is equal to or larger than 7 mm.
