Products description

Son 28 Dynamo Hub

For Rim Brake
 

Blue, Orange and Light green only available as 36-Holes Version!

 

SON 28 is a generally approved hub dynamo for all wheel sizes up to 700c (29"). On a 28"-wheel nominal output is reached at about 16 km/h (SONdelux at 19 km/h). SON 28 is recommended when more light is required at low speed or when other devices are to be operated or their batteries recharged.
Compared to the SONdelux, the appearance is similar but the flanges are more widely spaced by 12mm and the bearings by 10 mm.
