Semi Radial Spoke Pattern

SON developed the semi radial spoke pattern to compliment the extra compact and elegant design of the new SON XS. They positioned the hub slots for the spokes in such a way that, when lacing spokes, the straight pull spokes bend slightly as soon as they are tensioned. A purely radial spoke pattern would be trouble for these hub dynamos, as the pole sensitivity of the generator may cause audible vibrations of the spokes. The ingenious bend of the semi radial spoke pattern avoids such vibrations.

The SON XS Brompton dynamo hub is optimized for the small wheels and the narrow fork of folding bikes. Thus, the low weight and minimum no-load losses are achieved.
