Finishing nut (steering head nut) with 1 inch / 24G thread made of chrome-plated steel for the fork of your moped, moped and small motorcycle.
The closed steering head nut is suitable for handlebars with fork plate mounting.
As a special gadget, this fork end nut has a mount for the GPO cell phone holders. You can install the ball head of the various smartphone mounts here and secure it with the nut. This makes mounting on the handlebar easy and gives you a clean look.
Mounting on the steerer tube nut is much more elegant than normal handlebar mounting.
In addition, this adapter can also be used for other devices, such as a GoPro with a corresponding ball head mount.
