Shutter Precision hub dynamo PV-8 (silver / 32H)

The PV-8 is the lightest and most efficient 3.0-watt hub dynamo, specifically designed for racing bikes with rim V-brakes. The SP hubs have been tested for efficiency under the strict German StVZO "gold standard" specifications for bicycle dynamos at 15 km/h. The SP dynamos achieve an unmatched efficiency of 72% when the lights are on, making them 17% more efficient than their competing German and Japanese models. This efficiency significantly increases with higher speeds. SP dynamos are currently the most efficient dynamo hubs on the market. They are not only the most efficient but also the lightest hub dynamos available. The S and P series are 60 and 10 grams lighter than their closest German and Japanese competitors. Additionally, the SP hubs are practically drag-free, generating 50% and 25% less air resistance than their nearest German and Japanese rivals, respectively.
