BBT-169 Steel Bottom Bracket/Lockring Tool

Constructed from precision-machined 4140 steel, the Park Tool BBT-169 is a heavy duty tool for the removal and installation of select bicycle components with 16-notch tool fittings, including bottom brackets, center lock disc brakes, and e-bike motor lockrings. The BBT-169 is designed to be compatible with any bottom bracket with the corresponding tool fitting, with an extra-deep body to accommodate extra-wide spindles and low-profile walls at the point of engagement for recessed lockrings. The BBT-169 has three methods of tool engagement—a 3/8" drive fitting, a 1" hex fitting, and 36 mm wrench flats—allowing you to take on even the most seized bottom bracket cups. For added stability, the BBT-169 features integrated threads for use with the Park Tool BBT-RS Bottom Bracket Tool Retaining System or GPS-1 Guide Pins (each sold separately).
