I've been using the K-Edge mounts for years on my various bikes. When I updated my Garmin to a larger 1040 size I had to update all of my mounts as well unfortunately. I do love these K-Edge mounts though. Super strong, hassle-free and a nice bit of bling to boot. Biggest advantage over the standard plastic Garmin mounts is that it drops your computer in line with your handlebars and stem so it's a little more protected and possibly even more aero?
K-Edge makes great products, I have three of their mounts. This mount is strong and light for a handlebar mount. I never had any issues with any of their mounts, they are built to take it.
K-Edge is still king in this particular arena.
