Black silicone with lots of stretch and even more grip means you can mount nearly any phone nearly anywhere on your bike. Mount on your stem or top tube for directions and keep your handlebars clean. Or, mount on your handlebars with the camera facing out for some hands-free ride videos. Installs and removes instantly most anywhere. The stretchy silicone can hold other devices as well, like a hand pump, or a spare tube.
Bonus: the clasp doubles as a bottle opener. Cheers.
