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.
The new SON 28 relates to SONdelux regarding assembly and appearance. Compared with SONdelux the distance between flange and bearing of SON 28 standard version (non-disc) is 12 mm wider which results in a sturdier wheel. Hex axle included.
Available in 32 and 36 holes, polished aluminum. Disc versions or other colours available on special request.
