The mounts i got with them dont take up a whole lot of handle bar real estate. That sucks you lost them.Sadly yes. For the first one i know it was on a straight line since i felt something has hit my leg and I just checked if I still have phone and wallet on me. Since both were present I kept on going. Later I realised it was a handguard that hit me and I went back looking for it but didn't found it. Its all black so that may have something to do with it. For the second one I didn't even bother looking. My handlebar is pretty crowded since I have switch for lights and mirrors on it. That was the reason I decided to make holders on my own. If everything else fails I'll make another ones but much more robust. Just to be sure. I thought these would hold but apparently the stress was to high.
