Splined Sprocket - 21 tooth
The splined sprocket system enables consumers the ability to quickly and easily re-place/flip worn SPEEDHUB sprockets without the need for special tools. All existing customers need to do is purchase the special splined carrier and corresponding sprocket when their ex-isting sprocket wears out. After which, they need only purchase the cheaper splined sprocket. All retrofit SPEEDHUBs currently shipped from the Rohloff AG will be supplied pre-fitted with the splined carrier. Original threaded sprockets will only remain available while current stocks last.
