SONdelux SL Wide-Body Generator Hub


The generator hub we use on our own bikes! The connector-less SL system makes wheel changes easy: 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! Even better, with no exposed wires, there is no risk of wires breaking or connectors coming off!

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 internals are the same as all SON Delux generator hubs: lightweight and with ultra-low resistance.

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.

Made in Germany.

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.
