This adapter allows Cardo Freecom or Spirit intercom units to mount directly to HJC helmets equipped with the HJC Smart intercom mounting system. It replaces the factory Smart insert and provides a secure mounting point for your Cardo Freecom or Spirit intercom units.

    Unlike adhesive pads or clamp-style mounts, this adapter uses the helmet’s built-in mounting location to create a clean, low-profile installation that looks integrated with the helmet.

    Each adapter is 3D printed from carbon fiber reinforced PA12 nylon, a strong engineering material chosen for its durability and excellent impact resistance. It is designed to handle real riding conditions and holds up well to vibration, sun exposure, and changing weather and contains at least 50% recycled material to reduce environmental impact.

    Installation takes only seconds: remove the factory Smart insert, replace it with the adapter, then attach your Cardo mounting cradle.
