Abstract
A bicycle sprocket apparatus comprises a sprocket mounting member, a first sprocket, and a second sprocket. The sprocket mounting member includes a hub mounting portion and a sprocket mounting portion, wherein the hub mounting portion is structured to be mounted to a rotating hub that rotates around a rotational axis. The sprocket mounting portion includes a first sprocket mounting surface that faces in a first direction and a second sprocket mounting surface that faces in an opposite second direction. The first sprocket is disposed at the first sprocket mounting surface, and the second sprocket is disposed at the second sprocket mounting surface. A fastener fastens the first sprocket to the first sprocket mounting surface, and a chain supporting structure extends from the fastener in the first direction and projects in the first direction away from a side surface of the first sprocket that faces in the first direction.
