I have a Samsung S Advance smartphone, and I want to mount it on my racing bike. The only bike mounts I can find are either iphone mounts, or a few universal bike mounts, but these are all too small to fit on a racing bike's handlebars or stem. (appr. 4cm in diameter).
I'm a good-weather biker, so I don't need a water-proof case or bag, just a mount, and preferably as small as possible.
I've tried strapping my phone to the stem with elastic straps, which worked, but I'm afraid the vibrations will damage the phone, or that it might fall off.
Any tips are appreciated!
