SFHub - Silent Freewheel Hub

The SF-HUB has a noiseless freewheel and simultaneously excels with close to zero backlash. This instant engagement means that the energy that the rider applies to the pedals is transferred directly to the rear wheel without the annoying backlash. This is made possible due to a modified, innovative principle with regard to the conventional roller freewheel. An exceptional riding experience that will never cease to surprise every time.


The hub feels at home in many areas of use. Whether you are out on a relaxed cruise with your city bike or on gravel roads with your cyclocross — the hub's special properties will impress you every time you use it. It must be considered that the maximum torque of 180 Nm can't be exceeded. Due to its compatibility with all common gearshift systems, various frame mounts, and the 6-hole disc brake mount, there are hardly any limits to the available combinations.

The laser-engraved Kappstein-K on the black anodised finish additionally guarantees an elegant appearance.
