Cube Agree C62 SLT - Apple Airtag Holder Bike

Searched for a solution to mount an Airtag on my Cube Agree C62 SLT Roadbike and was not able to finde an solution, which was ok for me.

Mounting under the seat - too obvious.
Mounting under the bottle carrige as many designs already made, was not fitting well to the aerodynamic form of the bike.

So i found another solution.
Due to the C62 SLT has an SRAM derailleur, the bottom hole for the Shimano battery cage is empty.

Here was the best and not too obvious way to mount the airtag for me.

The airtag gets a bit scratched due to the distance between the holes is a little bit to small for the airtag.
