SONdelux is the first hub dynamo with a generator specifically designed for modern LED lights (such as Edelux and B&M Cyo). Other than halogen lamps, LEDs are highly effective even at low power, i.e. when run below the nominal power/ its rated capacity. This is the reason why dynamos no longer need to be build in a way for them to reach full power at the lowest possible speed. Therefore, SONdelux is smaller and lighter than a hub dynamo for halogen lighting (SON 28). No-load power input drops by about 30 - 35% compared to SON 28. But SONdelux equals SON 28 concerning durability and outstanding quality.

1 reviews for SON SONdelux dynamo hub disc Centerlock with an average rating of 4/5 points.
Reliable and Low drag dynamo hub with iso and centerlok options. I needed a dynamo hub for my commuter bike, Initially I bought a relatively cheap shimano unit. I was put off by the apparent high drag of this hub and it failed after just one yr. So I bought a Sondelux which I've now been using for 3 yrs without problem and has far less drag than the shimano. So I thoroughly recommend it. ★★★★★ Steve Mills
