The SON28 has a bit more power at low speed than the SONdelux so it's a bit better for those who use the hub's power for charging a GPS or mobile telephone on tour.
The Schmidt Dynamo front hub or SON (Schmidt's Original Nabendynamo) is extremely reliable and has almost no drag. Made by Wilfried Schmidt Maschinenbau in Tübingen, Germany, the hub is quiet and is designed to give at least 50,000 kilometers of trouble free riding between servicings. The hub powers many different six volt headlights including Schmidt's own Edelux II LED headlight and assorted taillights, both older halogen and LED headlamps and taillights made by Busch & Müller in Meinerzhagen, Germany, plus Supernova and Spanninga lights.
Many cyclists want to charge a cell phone or GPS while they ride. The SON hubs are ideal for keeping your GPS going. We have several AC to DC converters for this purpose.
When your bicycle can make its own light, it becomes a reliable means of transportation, not just a toy or play thing for an afternoon's entertainment or exercise. With an automobile, you take its lights for granted. You get in the car, turn on a switch, and drive on down the road with the light you need. With the SON, you can take quality lighting on your bicycle for granted, just as you do in a car, making your bicycle just as convenient to use for everyday transportation as an automobile.
SON dynamo hubs have a five year warrantee.
