Here they are at last: redesigned, new, small and narrow hub dynamos for folding bikes. Schmidt were able to make SON delux and SON 28 smaller and lighter owing to the spherical housing and reduced flange diameter. For SON XS, Schmidt had to advance technically: The new bodies have lateral slots instead of spoke holes. Straight pull spokes are placed into the slots as also found in system-wheels. This makes the wheel elegant and durable simply because there is no bending moment in the spoke elbow.

The new hubs are about 40 grams lighter than the previous XS models, which will continue to be for those devoted to classical design and polished surfaces. The new hub surface is anodized. Three standard versions (silver, black, silver-black-silver) are available from stock.

Connection Cable?
07 Mar 2015
Does the item include the connection cable for a front light or do I need to order it separately and if so, what exactly?

Thank you!
SJS Customer Service:

The cable that connects the front light to the hub dynamo is normally supplied with the light as in most cases it is hard wired into the front light.

What Length Spokes To Use With This Hub
06 Mar 2015
i.e., the Schmidt SON XS for Brompton Dynamo.
SJS Customer Service:

Spoke length can vary massively depending on the rim that a hub is being fitted too, without knowing what rim it is you are going to be fitting it with i can't give you any idea of spoke length I'm afraid.

I would like to use a double wall rim of the original Brompton hub Are there any straight spoke of precut?

SJS Customer Service:

Unfortunately we don't sell any straight pull spokes and there is none available from Brompton as all of their hubs use normal J-bend spokes.
