Timwrote a review of Wolf Tooth Components B-RAD Mounting Base on July 19, 2019
Familiarity: I've used it several times
had little room in my frame for a bottle cage when using the manufacturers bottle cage mounts. This gave me the flexibility to install my bottle cage so it did not interfere with the rear shock. sweet!
Be aware though, you'll need a T25 torx driver to install it with included fasteners!
