I recently upgraded from a Garmin Edge 500 to a 520. I`m using a Barfly TT mount and find my 520 isn't as secure as the 500 was in the mount. Even pressing the side buttons is enough that the unit twists in place. Right now I'm indoors on my trainer but I wouldn't trust it outdoors. Is there a better TT mount that I could use with my 520 ? The mount that came with the 520 is very good but I can't mount it on my P3 aero bars.
Thanks
