Introduction Spec

    Shutter Precision (SP) started in 2007, is a relatively new comer in the dynamo hub business. However, despite being new, their products have proven to be reliable and earned large number of favourable reviews worldwide. In addition to marketing their own brand, they also produce for others. There are testing reportings that SP hubs that have been running for more than 20,000 km without issues. Since 2019, Brompton uses the SP SV-8 as its hub dynamo factory option. 

    The SV-9, being slightly larger than a golf ball and weighing only 305g, is the smallest and the lightest dynamo hub we know.  The SV-9 meets German StZVO standard, and is rated at 6V/3W for 20" wheel.
     
    The Brompton spec SV-9 has 74mm axle width and 8mm axle diameter. The axle length is also sufficiently long to accommodate safety clip and mudguard stay.   

    The current batch of the SV-9 is the 4th revisoin, dubbed SV-9 FB4. The gloss finish is also a custom order
