Help me tighten up this cateye barend mirror.
 

This cateye mirror keeps moving down and droops down when i take some bumps.

I've tightened it to the max and it still does this. I don't want it to be static, because if I hit something i'd like it to give so it won't break and snap off.

You can rotate the holder so the bottom is at the lowest point you want the mirror to be at... and wrapping som electrical tape around the bulb and stem will help... I'm sure there are more ingenious ways to fix this problem but this has worked for me with that mirror... Hope this helps :)
