Fits:
24mm: BB90, BB95, BB86, BB92, BB121 (fatbike), includes all Shimano pressfit variants
29mm/30mm: SRAM DUB (all press fit variants, not BSA), BB30, BB30A, PF30
The tool works by gripping on the inside of the BB bearing or cup, you will need a screwdriver (or similar) and a hammer, to tap the tool from the opposite side; this will gradually knock the bearing or cup out of the frame. You can see the 29/30mm (BB30/PF30) version in our tutorial video here:

Also works with SRAM GXP press fit; you would use the tool to remove the 24mm side, then you are able to easily knock the 22mm side out using a larger drift such as a piece of wood.
