Details
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.
