Park Tool BBT-79.3 bottom bracket tool

A precision CNC-machined aluminum tool for the installation and removal of Rotor BSA30 Track bottom brackets. The knurled textured surface makes it a breeze to turn by hand, then tightened to correct torque using a 3/8" ratchet driver or torque wrench.   This fits a lot of other bottom brackets too, but nothing we sell or that is used on a track bike. specs • lightweight aluminum construction • shop quality for a lifetime of use
