Just saw this on Bike Rumor, new product "C-fast Versadjust" which includes a Go Pro mount. Looks like it could certainly fill a market place, but if I were to suggest an improvement on it, I'd make it so that the Garmin unit can be tilted a few degrees. Sometimes a person has the computer mounted up high, or directly downward if they looked straight down (which the current version would be fine for). Sometimes a person has it slightly closer to their stem--which would be cool if you could tilt it downward so if you're putting your head between your arms for a glance back in aero position to see the screen. Providing there is no BTA bottle that is.

I do like the left/right adjustment for centering though.
