The splined system allows you to quickly and easily replace worn SPEEDHUB sprockets without the need for special tools. All you need to do is buy the splined adapter and the corresponding sprocket when your existing sprocket is worn out. After that, you only need to purchase the cheaper sprocket with splined connection. All retrofit SPEEDHUBs currently supplied by Rohloff AG are already equipped with the splined adapter.
Order art.#8540 (splined adapter) if you are switching from an original threaded sprocket version to this sprocket.
A primary gear ratio of 3.0 or more is required when using the 13t or 14t sprockets.
This is necessary to prevent damage and personal injury from overloading these parts. This restriction applies to all application areas.
13t sprocket = smallest permissible chainring of 40 teeth
14t sprocket = smallest permissible chainring of 42 teeth
