Schmidt SON Delux Front Dynamo Hub
The SONdelux is the first hub dynamo generator specially designed to match with the requirements of modern LED headlights. SONdelux has received the German legal mark of conformity to be used together with the Edelux in all wheels of sizes from 16" up to 700c. SONdelux replaces the SON 20R, which is almost identical in construction. SON 20R had the legal conformity for 16" upto 20" wheels only. So now for nearly all applications SONdelux & Edelux are the ideal dynamo powered lighting system providing maximum illuminance at minimal physical effort.
