### ⭐⭐⭐⭐⭐ Great for my bike radar
*by R***E on May 28, 2026*

Great addition to my bike to more permanently attach my bike radar. I have 100 miles so far without any issues. Stem is standard 28.6 mm sized.

### ⭐⭐⭐⭐⭐ Do Not Hesitate to Buy This
*by J***Z on June 4, 2026*

Solid, strong Mount. Fits securely on my 27.5 post. Great product !

### ⭐⭐⭐⭐⭐ Easy to use and well worth it
*by F***N on November 22, 2025*

Great quality and well-built mount. I used the mount that came with the light for a few rides and was hesitant to get a fixed mount due to the angle of my seat post. But decided to give this mount a try and what a difference it made. Easy to install and holds up ride after ride. I liked it so much that I bought another one for my other bike. Highly recommend.
