Back in Stock: SON Hubs and Parts

SON generator hubs and other parts have been flying off the shelves lately. Some of it can be attributed to cyclists preparing their bikes for the upcoming Paris-Brest-Paris 1200 km brevet. More cyclists also realize that generator hubs provide peace of mind on long rides and commutes alike. As a result, some of the most popular hubs – especially the Wide-Body that makes for stronger wheels (above) – have been out of stock recently.

The new SON coaxial adapters also have been popular. Slide one onto the tabs of any SON hubs to convert it to the latest coaxial connectors. Then the wires are easy to plug in and out with one hand whenever you have to remove the wheel.

The Edelux II headlights, with their optimized beam pattern, also are available with ‘coax’ connectors now, making the system a plug-and-play setup that is super-easy to install on your bike.

The Splitter Box allows you to wire a USB charger or other device into the circuit from your light to your generator hub. It’s a great way to get the superior beam pattern of the Edelux II and still charge your devices on the go.

Production of all these parts now has caught up with demand, and all SON components in the Compass program are back in stock. We appreciate your patience while supplies were running short.

    Beautiful and highly instructive article regarding beam pattern. Being an cyclist, but also flasholic, I enjoyed learning sonething completely new and never mentioned on the forums. And the other articles and topics are on the same, highest professional level. Hope one day will have bike like yours (Weigle, Chapman, Singer). In the meantime, my faithfull Montello.
    Have a nice day

    Since I got my Edelux I my world has been illuminated.
    Recently though my SON deluxe hub has begun to make a loud rubbing noise when I switch on the light. Any ideas why or how to fix??? These hubs don’t seem easy to adjust on my own. Maybe I just don’t know how to maintain it properly.
    Being the expert that you are, any advice would be most helpful, and my guess is that I’m not the only one who has/ will experience this.

    • It’s hard to diagnose problems remotely, but switching on the light only changes the resistance, but nothing mechanically on the hub. So if the noise isn’t there when the light is off, then it’s probably not the hub, but something else on the bike making noise as the resistance and slight vibrations of the hub increase with the light turned on.

      If the noise is always there, with the light on or off, then something inside the hub may be rubbing. The hubs aren’t user-serviceable. Return it to a distributor, who can overhaul it for you.

      I had to send mine back because the stator had become loose. If I remember correctly the noise only happened when lights were switched on. Anyway, whatever the noise it’s not normal and you can’t do any repairs yourself…

    Funny you should mention the hubs being back in stock, as I am in the market for a new front wheel. ‘Tis a pity that Compass doesn’t offer any wheels/parts for 26-inch wheels, or I’d grab one with the SON delux hub (and the coax connector, too). I might order a hub anyways to eventually build up into a complete wheel.
    Do you feel any resistance from the hub when the lights are switched? How about resistance when the lights are off, compared to a high-quality, non-dynamo hub of comparable size?

    • The resistance from the hub with the light off is negligible. It slows you by less than 0.1 km/h, and you don’t feel any difference.

      With the light on, the resistance goes up a bit. How much depends on how much power you draw. With an Edelux headlight and the Delux hub, you’ll slow about 0.4 km/h at 25 km/h… It’s noticeable only if you are going all-out in a group of well-matched riders.

    Has anyone heard whether an asymmetric Edelux light for those of us who live in countries keep to the left will ever be available, or any other brand that does so?

    • Jan Heine says:

      The Edelux is only asymmetric in the vertical plane, not right-to-left. (It’s not like the low beam of cars that put more light on the outside of the road.) So there is no need for a British/South African/Australian/Japanese/etc. version. Just use the standard Edelux II.
