SON 28 Disc hub dynamo

The SON 28 hub dynamo is universally approved for all wheel sizes from 16" to 29". It reaches its nominal power in a 28" wheel at approx. 16 km/h. This makes it highly recommendable when you ride slowly and need a strong light or when you want to use or charge other devices, e.g. a navigation system or smart­phone. Compared to its predecessor, no-load losses have been reduced by approx. 15% and weight by approx. 140 g.
· 65% efficiency at 15 km/h in a 28" wheel
· Power consumption when idling: 0,5 watt at 15 km/h in a 28" wheel (corresponds to a gradient of 12 cm over 1 km)
· Threadless hollow axle made of cold harden­ed, stainless steel
· Hub sleeve made of aluminium 6082 T6
