Made this adapter for my Cardo Freecom 4x. I made the adapter in a way that uses the original hole for the X-Com. you need to use the adapter that comes with the helmet.
This adapter can be fitted with a Freecom 4x, Freecom 2x, Spirit and Spirit HD.
This Adapter can be inserted in the following helmets:
NEXX X.WED2 CARBON
You need to swap the screws that are present in the helmet for one that is bigger in lenght.
If you have any question please let me know :)
