Abstract
A bicycle rear hub is configured to improve the external appearance and the resistant to corrosion of a drive body. The rear hub also has a hub shaft, a hub shell, a pair of bearing units, a one-way clutch, a sprocket, and a cover member. The hub shell is rotatably mounted to the hub shaft by the bearing units. The drive body is mounted to one end of the hub shell by the one-way clutch that transmits rotation from the drive body to the hub shell in one direction. The sprocket is fixedly mounted to a radially outward-facing surface of the drive body. The cover member is mounted to the drive body 19 to cover the radially outward-facing surface of the drive body and with its tip edge contacting the outside lateral surface of the sprocket.
