We are excited to announce the latest SON generator hubs. The biggest news is the connector-less SL system for thru-axle hubs: Now you can remove your front wheel and its generator hub without having to disconnect any wires, even with a thru axle.
The system consists of three parts: The heart is the SONdelux 12 generator hub. The SONdelux is the lightest generator hub in Schmidt’s program, and it has the least resistance, so it was a natural choice for this application. The flanges are spaced as far apart as possible while still leaving room for the disc rotor and caliper.
This hub has proven itself for many thousands of miles. What’s new is the lack of external connectors for the lighting wires. The current is transmitted via the axle (positive) and an insulated ring that is pressed onto the axle (negative). Like its counterpart with external connectors, the connector-less SL hub is available in black or silver.
The hub mates to a special dropout. By the way, the machining traces that form the funky pattern in the photos can be removed by your framebuilder. Above you see the outside, which looks like a standard stainless steel dropout for 12 mm thru-axles (12 x 1.5 mm thread).
It gets more interesting on the inside, where one dropout has a recess…
… into which an insulated contact plate fits. As you install the hub, the axle connects to the dropout for the positive contact, while the insulated ring on the hub mates to the dropout’s contact plate, which is insulated as well. A wire goes inside the fork leg from the contact plate through to the lights. That way, you provide a path for the current to flow from the hub to the light without any exposed wires that can get snagged or break from repeated flexing during installation and removal of the front wheel.
We have a small number of contact plates and dropouts in stock, with more to come once production catches up with demand. And of course, the connector-less SL system has been available for non-disc hubs all along, and we have those components in stock, too.
That isn’t all the generator hub news! Many modern rear hubs are black, and we are now offering SON hubs and lights in black to match. We’ve worked with Schmidt Maschinenbau to make our favorite hub, the SONdelux Wide-Body, in black, too. The black hub is available in the standard and connector-less SL versions, with 32 holes. This is a one-time production run, so quantities are limited. If there is sufficient demand, Schmidt will make more for us, and in other spoke counts, too.
We also have the SONdelux Centerlock Disc for quick release forks in black…
… and the Edelux II headlight for hanging mounting. (We’ve been stocking the ‘standing’ Edelux II in black all along.) Now you can choose between silver and black components when equipping your bike with the best and most reliable generator lighting.
