Compact key for casing

Bottom brackets sometimes need to be removed for maintenance, replacement, or upgrading. The Park Tool BBT-32 is compatible with 20-tooth bottom brackets with a diameter of 32 mm. This fitting is found on many cartridge bottom bracket models, including Shimano®, Truvativ®, RaceFace®, FSA®, and others. It also fits certain models of bottom bracket locknuts, including Race Face®. The tool releases oversized axles on ISIS Drive and Octalink® cranks. It can be driven using a adjustable wrench or a 32 mm socket.
