SON hub dynamo SON 28 | 9x100 mm quick release
The SON 28 is a hub dynamo that is universally approved for all wheel sizes 16 "to 29". It achieves its rated power in a 28-inch bike at around 16 km / h (SONdelux 19 km / h). It is therefore recommended if a lot of light is required when driving slowly, or if other devices are to be operated or their batteries are to be charged.
The new SON 28 is similar in structure and appearance to the SONdelux. In the standard version (non-disc), the flange spacing and bearing spacing are increased by 12 mm and 10 mm compared to the SONdelux.
Compared to the SON 28 classic (model year 2000 to 2011), the idle losses were reduced by approx. 15% and the weight by 140 g.
