SONdelux SL Wide-Body Generator Hub


The generator hub we use on our own bikes! The SL “connector-less” system simplifies wheel changes: 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 Delux Wide-Body features extra-wide flange spacing (68 mm vs. 50 mm) and a steel axle for a much stronger wheel. This hub is strong enough for off-road racing and even tandems. The wider flanges also make for a better-looking wheel, with less space between the spokes and the fork blades.

The internals are the same as the Delux generator hub: lightweight and with ultra-low resistance. The weight penalty over the standard Delux amounts to just 27 grams. This combination of features makes the Wide-Body the best choice for most riders.

Note: The SL system requires a fork with special dropouts that feature a built-in connecting plate. This generator hub is also available with standard connectors to fit all bikes with quick release wheels.

We also offer rims and spoke kits to build a complete wheel with this 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. Schmidt Maschinenbau in Germany has pioneered modern generator hubs since introducing their first SON model in 1995. The latest models are lighter, have less resistance and last longer than other generator hubs.
