If you ride your bike enough, especially if you get your kicks in more extreme conditions like mountain biking, 'cross, fat biking, and gravel, your in-the-shell bottom bracket will need some loving or replacing. Park Tool's got your back once again and has you covered with the Bottom Bracket Bearing Tool Set - BBT-30. 4.The BBT-30. 4 Bottom Bracket Bearing Tool Set is specifically built to install and remove the bearings used in BB30, PressFit 30, 386EVO, BBright, and PF121 bottom bracket systems. The BBT-30. 4 comes with adapters that, when used in conjunction with a headset cup press, quickly and precisely presses BB30 bearings or PF30 cups into the bottom bracket shell. The included BB30 bearing remover works through the shell and with a hammer, easily punches out the bearings. Its length is long enough to reach bearings even on wider fat bike shells.
