B-RAD Mounting Bases

does what it says, but more importantly it’s ROCK SOLID. still allows for secondary attachments behind, such as frame pump mount (silca tattico, in my specific case). love it and will definitely outfit my other bikes with other items in this line.

This was able to move down my Mount so that I could use an even larger water bottle on my in frame bottle mount. I can now get a 1 l bottle into my bike frame without contacting the frame with the lid

Does exactly what you think it does. My bottle fit lower in the frame now when using my half frame bag. All good
