Bottom Bracket Tool — 20-Spline

Bottom brackets occasionally require removal for service, replacement, or upgrading. The Park Tool BBT-22 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. The investment-cast steel body utilizes a flat tooth profile to ensure maximum engagement with bottom bracket cups. Can be driven using a wrench, socket, or 3/8" drive wrench.
