Abstract: A bicycle sprocket comprises a first member and a second member. The first member comprises a plurality of first teeth and a first body. The first body includes a plurality of first arms arranged in a circumferential direction of the bicycle sprocket. The second member comprises a plurality of second teeth and a second body. The second body includes a plurality of second arms arranged in the circumferential direction. The second member is configured to be attached to the first member so that an interior cavity is provided between the first member and the second member. The interior cavity is at least partially provided between at least one of the first arms and at least one of the second arms facing the at least one of the first arms in a state where the second member is attached to the first member.
