Bottom brackets occasionally require removal for service, replacement, or upgrading.
The Park Tool BBT-32 is compatible with bottom brackets with 20 splines and a diameter of 32 mm.

This fitting is found on many models of cartridge bottom brackets, including Shimano®, Truvativ®, RaceFace®, FSA®, and others. Also fits some models of crankset lockrings including Race Face®.

The tool clears the oversized spindles of ISIS Drive and Octalink® cranksets. Can be driven using an adjustable wrench or 32 mm socket.
