Abstract: A bicycle rear sprocket assembly comprises a plurality of sprocket members and a supporting member. The plurality of sprocket members have a rotational center axis. The plurality of sprocket members are arranged in an axial direction parallel to the rotational center axis. The plurality of sprocket members each include a sprocket body and a plurality of sprocket teeth. The plurality of sprocket teeth extend radially outwardly from the sprocket body with respect to the rotational center axis. The supporting member is a separate member from the plurality of sprocket members. The supporting member includes a supporting portion and a hub engagement portion. The supporting portion is configured to support the plurality of sprocket members. The sprocket body of each of the plurality of sprocket members is attached to the supporting portion of the supporting member without using a separate metallic fastening member.

Abstract: A composite bicycle component comprises a first member, a second member, a bonding member, and an inner holding member. The first member is made of metallic material. The second member is made of non-metallic material. The first and second members are configured to form an interior cavity therebetween in a state where the first and second members are attached to each other. The bonding member is configured to attach the first and second members to each other. The inner holding member is configured to be disposed within the interior cavity so as to prevent the first and second members from being separated from each other until completion of attaching the first and second members to each other.
