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.

Axle Material

Does this hub use and aluminum axle? Wondering if that's how they got it so light.



We believe this axle is alloy.

Can You Confirm This Hub Is Suitable For 700C Wheel, Thank You.
10 Jan 2016

This hub is indeed suitable for use within a 700C wheel.

Which Schmidt Light Would You Recommend With This Hub?
16 Nov 2015

Any of the Schmidt front lights would be compatible with this hub, so you can chose whichever you require. We'd recommend going for the 140cm cable length and cut it down to length you need as this way it does not come with the incorrect fittings already fitted. The bare cables can be fitted into the plug fitting that is supplied with the SP hub.
