From a distance, what may look like a standard hub when fitted to your wheelset is actually hiding a dynamo. DT Swiss collaborated with Shutter Precision, a market leader for dynamo hub technology, smoothly integrating their SP PL-7 generator into a tailored hub shell. The 350 Dynamo Front Hub generates electricity from the rotation of the front wheel to power your lights and other electrical devices. This adds some resistance, but thanks to the design of the hub shell and the efficiency of the SP PL-7, it has a minimal effect on your ride. Efficiency is measured both with the light on and off.

• The SP PL-7 generator incorporates one of the most efficient technologies. At 15 km/h, while delivering a standard output of 6 volt/3 watts (6V3W), 4.2 watts of your rolling power are used to power the lights
• With a tailor-made hub shell, you can rely on the build quality you expect from DT Swiss hubs, with the added technology of Shutter Precision. With its rugged construction, the dynamo hub is ready to withstand the rigors of your off-road riding, including rough terrain, heavy loads and exposure to the elements
• Compliant with German road traffic regulations (StVZO). It’s designed to provide adequate visibility for riders and other road users, reducing the risk of accidents. Additionally their 6V3W rating ensures compatibility with standard hub dynamo products including dynamo lamps and converters for USB powered devices
