Review on 🔧 Park Tool BBT-30.4 Press Fit Bottom Bracket Bearing Tool Set - Versatile Compatibility with BB30, PF30, and More! by Brian Delgado

This allows you to REMOVE the BB30 bearings but not install them yourself. In the picture you can see the main removal tool, as well as two installation "cups". These mounting cups are used during the installation process, but this tool alone cannot install bearings. The description may be a bit unclear, but I'm familiar with press-fit type bearings, so I knew right away that I would need an additional tool to install them. The removal tool works fine, just make sure it's actually installed in the old bearing before hitting it with a hammer. This will ensure the bearing comes out clean and easy without damaging anything. If you need to install new bearings, do yourself a favor and make a press out of $3 parts from the hardware store. (threaded rod + washers + nuts). Make sure the bearings go in straight during installation. The only way I could buy a Park Tools press would be if I installed several sets of pressfit bearings a week, a hack job at the hardware store is perfect for the occasional bearing change.
