Looking for a phone holder. I’ve seen people struggle getting the stem mounts to fit. Was wondering if there are any other options
Yes. you may try this: https://ca-buybits.glopalstore.com/..._medium=wi_proxy&utm_content=en_GB&utm_term=c
You may just need another craddle. It's the clip-on bar end base that's the important part. https://ca-buybits.glopalstore.com/..._medium=wi_proxy&utm_content=en_GB&utm_term=c Quadlock will work for you but you will require a ball end extension that mounts to the ball end base.
Quad lock make a ant-vibration unit that stops issues with optical stabilisation damage on phones. Used one for a couple of years now and never had a problem with the camera on my phone.
I use the ultimateaddons phone holder which is waterproof and allows the charging cable to be connected at the same time.
I have another option. Put your phone in your pocket. It's a distraction that could kill you. And here where I live it's a $647 fine for distracted driving...
