Mobile Ball Mount Adapter, Locking, Non-Charging, SlimLink Mounting Technology, Push Button Release, Works with 20mm Ball-and-Socket Phone Mount for Car, Truck, Motorcycle, Boat and More

I wish I would've come across this style of mount sooner, it is far superior to any other mount I've tried. It works seamlessly with the Peak phone cases and has never come loose while getting knocked around driving down the road.

専用なのでケースの取り付けは問題なし、ただキャッチの方は他社でも同様の機能の物がありますから インチセンチの仕様違いは要確認です

I love this mount......my phone is so safe and secure.

ピークデザインのケースを利用している為、バイク用のマウントに必須のアイテムです。同じようなスマートフォンのマウントも存在するが、ケース自体がゴツくてダサいためピークデザイン一択。ただし、この製品には20mmと1インチ（約25mm）の2サイズがあります。日本で手に入るバイク用のボールジョイント(ラムマウント)は1インチが主流です。私の様な間違いをしないように注意しましょう！！

Alright, so you've got some random phone mount with a 20mm ball, maybe for your motorcycle or whatever, but you wanna use your cool Peak Design phone case with it? This Peak Design Mobile 20mm Ball Adapter is pretty much exactly what you need. You just swap out the old phone holder part on your mount for this adapter. It clicks right onto your Peak Design case super fast and feels really secure – like, surprisingly solid. It's way less fiddly than some other mounting systems. So yeah, if you're already in the Peak Design mobile world and have a 20mm ball mount chilling, this thing is a no-brainer to make them play nice together.
