Review on 🚲 XOSS Bike Cellphone Holder - Premium Aluminium Alloy Mount for Mountain & Highway Bicycles - Adjustable Mobile Phone Stand for Handlebar & Stem (Gold) by Seth Damain

This is for the "G-85" 4-pin design. Measured with a caliper. The distance from the outside of one post to the outside of the other post is 50mm. From the inside of one stand to the inside of the other stand is 34.6mm. Each post is 7.7mm wide at the base and 11mm high. When using the supplied clamp without spacers, the maximum distance between the clamp bar and the bottom of the bracket is 17.8mm. (You will have more clearance if you attach a smaller stem and use the spacers provided.) The clamp is 31.8mm in diameter but can be adjusted larger or smaller. because the black pads are made of hard plastic and slide by themselves. Tip: If the grips are too thick, you can cut open an old bicycle inner tube and use this. Just rinse off the powder beforehand.
