Hello Ladies and Gentlemen,
I would like to share with you a tip that I found in September 2019.
You can mixed a Garmin Edge mount with a mount included in the Tri Pack F945 (same as F935).
Look at the picture below for an exemple.
I used a Trek Bike + Bontrager Blendr XXX Garmin High Mount (for Garmin Edge, a low mount exist) + my mount included in Tri Pack Forerunner 945.
You can find the same integrated system for your bike, it's depend of your handlebar.
Enjoy
