As I wanted to have the Piko R in a center position in front of the handle bar. I found (for me) the perfect solution to mount it below my Garmin EDGE 1000. Now the Piko is completely out of my sight and is in a perfect center position even the Garmin is still centered in front of the handle bar.
With the Lupine GoPro adapter it is now attached to the K-EDGE XL. Maybe also interesting for others.
