Description The SP SV-8 Dynamo Hub is a 6V 3W Output front hub from Shutter Precision that suits a rim brake bike using a Quick Release axle. Unlike other hubs from Shutter Precision, this hub will offer a 6V 3W output on a 20″ wheel, but only 6V 2.4W on a 26″ wheel. Designed primarily for small wheeled bikes like cargo bikes or folding bikes with rim brakes & Quick Release skewers. This hub will still work for a 26″ wheel, after the speed of 15km/hr the output is almost the same as for a 20″ wheel. So if you ride fast, this hub will work for you! Why Shutter Precision over other dynamos? Shutter Precision have been making dynamo hubs for decades, and we love their quality & reliability. We at Abbotsford Cycles absolutely recommend Shutter Precision hubs for your next wheel build for their serviceability & long life. Compatibility notes This hub from Shutter Precision is designed for wheel sizes from 20″ up to 26″. And it’s designed for a rim brake bike using a Q/R skewer with 100mm OLD. Ensuring the hub you choose works with your current wheel size, brake type & axle type is critical. If you are in any doubt about what you need you can give us a call & we can work through it together. Once you start looking at other cyclists set ups, you will see how many SP hubs are rolling on the roads!
