Basically your only option for Enve aero stems, but it does the job, is pretty sleek and clean to match the Enve aesthetic. Not super light weight and is a bit of extra work if you need to remove it to pack your bike, but still well worth it!
This k-edge mount is sturdy but rather heavy (50 grams with garmin insert) for a computer mount. Over-engineered in my humble opinion. You would hope that its lighter considering it goes with a pricey carbon aero stem and handlebar. Also not sure why they cant make the arms just a little longer to accommodate the 10 series garmin edge devices.
I am using the 17 degrees adapter on the Enve stem and the mount angle points a little too far down for my liking.
