Review on 🔧 16-Notch Bottom Bracket Tool by Park Tool - Compatible with Shimano BBR60, MT-800, and More by Dave Brummet

This is a bottom bracket tool. If you have a compatible bottom bracket (in my case Shimano 105 R7000 2018+) then you know you absolutely need this adapter to remove or install it and nothing else will do. If you don't, it becomes a handy (albeit more expensive) paperweight. As always, the workmanship is first class with Original Park Tools. Might be cheaper, but hey, he'll always be there, always working. You will need a 3/8 inch socket wrench, but if you buy one you probably already have one.
