Abstract: A bicycle hub assembly comprises a hub axle, a hub body, a sprocket support body, and a freewheel structure. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface. The freewheel structure includes a first ratchet member and a second ratchet member. The first ratchet member includes at least one first ratchet tooth. The second ratchet member includes at least one second ratchet tooth configured to engage with the at least one first ratchet tooth in a torque transmitting manner.

Abstract: A bicycle sprocket assembly is basically provided that includes a sprocket support member, a first sprocket, a second sprocket that is a separate member from the first sprocket, and a third sprocket that is a separate member from the first and second sprockets. The sprocket support member is configured to support at least one of the first, second and third sprockets. The sprocket support member includes a plurality of sprocket support portions extending radially outwardly from a central cylindrical portion. A first reinforcement member is attached to at least one of the first and second sprockets, and extends between the first and second sprockets. A second reinforcement member is attached to at least one of the second and third sprockets, and extends between the second and third sprockets. Each of the first and second reinforcement members is disposed between an adjacent pair of the plurality of sprocket support portions.

Abstract: A bicycle sprocket assembly is basically provided that includes a sprocket support member. The sprocket support member includes a hub engagement portion, a first sprocket supporting member, and a second sprocket supporting member. The first sprocket supporting member extends from the hub engagement portion in a first axial direction parallel to a rotational center axis of the bicycle sprocket assembly. The second sprocket supporting member extends from the hub engagement portion in a second axial direction parallel to the rotational center axis. The second axial direction is opposite to the first axial direction. At least one of the first sprocket supporting member and the second sprocket supporting member includes a plurality of sprocket supporting arms.

Abstract: A bicycle hub assembly comprises a hub axle, a hub shell, and a sprocket support body. The sprocket support body includes a tubular part, a first sprocket engaging tooth, and a second sprocket engaging tooth. The tubular part includes an outer peripheral surface and an attachment portion. The first sprocket engaging tooth includes a first radially outer surface provided radially outward of the outer peripheral surface. The second sprocket engaging tooth includes a second radially outer surface and a third radially outer surface. The third radially outer surface is provided radially outward of the outer peripheral surface and radially inward of the second radially outer surface. A first distance is defined from the outer peripheral surface to the first radially outer surface. A second distance is defined from the outer peripheral surface to the third radially outer surface. The second distance is shorter than the first distance.

Abstract: A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first ratchet member, a second ratchet member, and a holding member. The sprocket support body includes a first helical spline. The first ratchet member includes at least one first ratchet tooth, and a second helical spline configured to mate with the first helical spline. The second ratchet member includes at least one second ratchet tooth configured to mate with the at least one first ratchet tooth, and a hub shell engagement portion configured to engage with the hub shell. The holding member is configured to hold an assembled state where the sprocket support body. The first ratchet member and the second ratchet member are assembled as a single unit.
