SON hub dynamo SON 28 12 Disc Centerlock | 12x100 mm thru axle
Until now, racing cyclists or gravel bikers with a 12 mm thru axle on the front wheel had to rely on battery-powered lights. Although these also have enormous lighting power, it quickly became dark when the power supply stopped. SON has also been able to help these cyclists. Not only is the hub dynamo compatible with thru axles, it can also accommodate Centerlock brake rotors.
The inside of the dynamo can be seen as a reference in this area. The claw pole generator works absolutely inconspicuously and hardly causes any noticeable rolling resistance during operation or idling. Thanks to a unique pressure equalization system and high-quality SKF deep groove ball bearings sealed on both sides, moisture has no chance of penetrating. In addition, the spoke holes have been drilled in such a way that the spokes have an optimum fit and it will not be necessary to re-center the wheel over a longer period of time.
All SON products are developed and produced in Germany. This means that the manufacturing process can be optimized at all times and consistently high quality can be guaranteed. They also come with a 5-year guarantee.
