SON hubs and lights include normal spade connectors — trim wires to length, crimp on connectors and connect to your hub. Anyone can manage this system and it works well. As an upgrade, SON offers a coaxial version that I put together today. This system requires more effort to assemble (basic soldering required) but pays you back with a number of advantages.
The upgrade comes with an adapter that connects a coaxial plug to the hub spade connectors. The new plug interface is spring-retained, which is more refined than the friction fit of spade connectors. The coaxial plug is secure but can be fitted or removed with full-fingered gloves. As well a single plug presents no opportunity to reverse pins, which is an issue with dual connectors.
