Description The SP PD-8 Dynamo Hub is a 6B 3W output front hub from Shutter Precision that suits a Quick Release 6 Bolt Disc brake set up with 100mm OLD. Available in 32H & 36H. A nice feature of the ‘8’ series dynamo’s from Shutter Precision is that they will run at 72% efficiency at 15km/hr. Meaning you don’t have to be steaming along to have your lights on. Which is great if you will be using the hub primarily for commuting in an urban environment. 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. Additionally, these hubs are low weight with a sturdy construction and a clean silhouette that will disguise their purpose. One of the other important features of this hub is it’s strength against the serious pressure from disc brakes. Compatibility notes This hub from Shutter Precision is designed for wheel sizes from 26″ up to 700c/29″. And it’s designed for a 6 Bolt disc brake, on a Q/R skewer 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!
