Full power even at slow speeds: the Son 28 6-bolt hub dynamo by SON


The SON 28 is a hub dynamo universally approved for all wheel sizes from 16" to 29" . It reaches its rated power in a 28" wheel at about 16 km/h. It is therefore recommended if a particularly bright light is required when driving slowly or if other devices are to be operated or if batteries are expected to be charged. Compared to its predecessor the Son classic, the power loss during idling has been reduced by approx. 15% and the weight by has been decreased by 140 g.
Disc version with 6-bolt brake rotor mount.

verified purchase
item: black/36 hole

Mated with Edelux II front light, Supernova E3 tail light and Igaro D1 power conditioner for device charging. Silent and worry free operation with excellent power output even at lower speeds. It's premium but worth it.
