The slimmest high-output dynamo hub from SON, handmade in Germany.
The SON 29 S packs a full-power generator into a body so narrow you'd hardly guess it's a dynamo. A redesigned generator reaches its rated 6 V / 3 W output at lower speeds, so it delivers full power even in 29" wheels. Paired with modern charging electronics, it produces exceptionally high output for lights and USB charging. Winner of a Eurobike Gold Award.
