SONdelux SL Wide-Body Generator Hub


Generator hubs provide light when you need it. No batteries to charge, no worries about running out of juice. Simply turn a switch, and your lights come on. And with the SL “connector-less” system: No more wires! Using a special dropout on your fork, the electrical connection is automatic: One pole is routed through the axle (and your frame), the other through an insulated ring that mates with a corresponding, insulated ring on your dropout. Simply insert the wheel, and the light is connected!

The latest SONdelux hub from Schmidt Maschinenbau, pioneer of generator hubs, is lighter, has less resistance and lasts longer than any other generator hub.

The “Wide-Body” model has widely spaced flanges (68 mm vs. 50 mm) and a steel axle to make a stronger wheel. Many also prefer the “Wide-Body” for aesthetic reasons, as the wheel fills out the fork more.
