6V 1.5W Ultra compact dynamo hub for wheel size 400mm(16”) to 535mm(20“)

Unique aerodynamic shape, low resistance and super light weight, make for and increadably efficient hub.

The unique aerodynamic shape of the hub has been optimized to a golf ball size, while attaining an unprecedented weight of only 309g.

Output Notes from Shutter Precision
The SP-9 Series real output is 6V 3W for 20”, however for 26”/700C its output is very close to 6V3W but still a little bit less at low speed & therefore, it cannot pass German StVZO regulation. For the German market SP must get StVZO approval so the 9 series was used to apply the new regulation i.e. 6V 1.5W LED. And 9 series got 6V 1.5W LED StVZO approval.

I recommend this product
ConsSilver version gets very grubby
ProsSmall, light, efficient
I have two of these and they run much more freely than an SV-8 that I also have. They are alao compact, lightweight, and can be laced radially to save a few more grams.

The silver-painted one gets dirty if you ride in the wet, and the satin finish makes it almost impossible to clean. It is best to stick to the black one.

What Spoke Length Required For 26" Build ?
29 Jul 2015
Very interested in the SP SV9.
What spoke length is required to build this into a 26" wheel or is the flange diameter such that it should swap out for a standard hub ?
Also what comes in the box (cables etc.) and what lights do you stock that are compatible (front and rear, connectors etc.)

The spoke length varies not only with the type of hub fitted but also depends on what rim you have fitted. The only thing supplied in the box is the connector cap that you fit to the end of the cable. As a suitable end cap is supplied, nearly every dynamo front light will be compatible with this hub, some may just require a small amount of adjustment to the cable to fit in the supplied connector cap.
