The Park Tool BBT-69.4 is an extremely versatile 16-notch bottom bracket tool: it installs and removes external bearing threaded bottom bracket cups from many brands and, with the same fitting, also works on Center Lock disc rotor lockrings and on the lockrings of some Bafang mid-drive motors.
It is precision CNC-machined from aluminium, made in-house by Park Tool and anodized for instant identification. The 16 notches have a major diameter of 44-45 mm and a minor diameter of 42.7 mm. The 3/8" square drive lets you use it with a ratchet or torque wrench, so every cup or lockring is tightened to the correct torque. One tool for cups and lockrings means fewer tools on the bench and less time spent looking for the right one, a real advantage in a workshop that works on different bikes every day.
