Abstract: A lock device comprises a first lock member and a second lock member. The first lock member includes a first axial end, a second axial end, and a first surface. The first axial end is configured to be detachably attached to a sprocket support body of the rear hub assembly in a mounting state where the plurality of rear sprockets is mounted to the rear hub assembly. The second lock member includes a third axial end, a fourth axial end, and a second surface. The third axial end is configured to be attached to the second axial end of the first lock member in an assembled state where a smallest sprocket and the lock device are assembled as one unit. The lock device is configured so that the smallest sprocket is slidable relative to the lock device in the axial direction in the assembled state and before the mounting state.

Abstract: A rear sprocket assembly comprises a first sprocket, a second sprocket, and at least one tooth-position maintaining member. The at least one tooth-position maintaining member is configured to maintain a relative position between a plurality of first sprocket teeth and a plurality of second sprocket teeth in a circumferential direction with respect to a rotational center axis. The at least one tooth-position maintaining member includes a fixed portion and at least one guide portion. The fixed portion is configured to be fixed to one of the first sprocket and the second sprocket. The at least one guide portion is configured to engage with the other of the first sprocket and the second sprocket such that the other of the first sprocket and the second sprocket is slidable relative to the one of the first sprocket and the second sprocket in the axial direction.

Abstract: A rear sprocket assembly comprises a sprocket carrier, a first sprocket, and a second sprocket. The sprocket carrier includes at least one sprocket mounting portion having a first radial section and a second radial section. The first radial section has a first maximum axial length with respect to the axial direction. The second radial section has a second maximum axial length with respect to the axial direction. The second maximum axial length is larger than the first maximum axial length. At least one second mounted portion of the second sprocket is configured to axially contact the first radial section and the second radial section of the at least one sprocket mounting portion of the sprocket carrier with respect to the axial direction.

Abstract: A sprocket support comprises at least ten internal spline teeth configured to engage with a bicycle hub assembly. The at least ten internal spline teeth of the sprocket support includes at least ten internal-spline driving surfaces. The at least ten internal-spline driving surfaces each include a radially outermost edge and a radially innermost edge. A radial length is defined from the radially outermost edge to the radially innermost edge. A total of the radial lengths of the at least ten internal-spline driving surfaces is equal to or larger than 7 mm. At least one internal-spline driving surface of the at least ten internal-spline driving surfaces has a first internal-spline-surface angle defined between the at least one internal-spline driving surface of the at least ten internal-spline driving surfaces and a first radial line. The first internal-spline-surface angle ranges from 0 degree to 10 degrees.
