6V 1.5W Ultra compact dynamo hub for wheel size 400mm to 658mm

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 only 299g.

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.

Its output is definitely not 1.5W. Shimano 1.5W hub output is real 1.5W. We don’t like it & also we checked 1.5W with other dynamo lights. It is not enough. Although 9 series is marked with 1.5W, its real output is much higher than 1.5W.
