Aw crap, I'll have to fix the pics later. Thanks for the heads up..
The initial road test results are in though. The 920 is obviously too heavy and flew out of the mount the very first bump I hit with the bike.. (good thing I have an otterbox case on it!) I guess this thread has FAIL written all over it! lol *facepalm*
Well there's the pics... I was thinking maybe a couple thick rubber bands wrapped around it to keep it from popping out of the mount over bumpy terrain.
Road test #2 tonight!
They also sell a bike mount in the wpcentral store that holds the 920 well. It's a tight fit but it works. The zipper just broke on mine and my wife bought a holder at the trek store that mounts on the top of the handlebar post that I really like so I will be getting one of those to replace mine. The one from trek is very slim and fits the 920 like a glove.
Added a couple more pics to the first post. The mount has been working well now that I figured out that it has two telescoping "feet" at the bottom of the mount to support the phone even more.
