SON 28 15 mm Disc Centerloc 110 mm


The ultimate generator hub for mountain and adventure bikes with 15 mm thru-axles and 110 mm Boost Standard. The internals are the same as Schmidt’s proven SON 28 hub: There is a little more resistance than with the SONdelux, but the upside is more light at low speeds – ideal for riding in rough terrain. The widely-spaced flanges make it easy to build a strong wheel.

Pro Tip: Make sure your thru-axle is well-lubed and tight. Otherwise resistance can turn the hub axle in the fork when the light is turned on. This can damage the connectors.
