More info: parktool.com/BBT-169

Constructed from precision-machined 4140 steel, the BBT-169 is a heavy duty tool for the removal and installation of select 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).

Fits 16-notch tool fittings with a major diameter (outside of notches) of 44–45 mm and a minor diameter (inside of notches) of 42.7 mm, including:

• Threaded bottom bracket cups from Campagnolo®, Chris King®, FSA® MegaExo®, Hope™, SRAM®/Truvativ® GXP®, Race Face® X-type, Surly®, Wheels®, Fulcrum®, and others
• Center lock disc brake rotor lockrings
• Bafang BBSH, BBS02 mid-drive motor lockrings

• 3/8" drive fitting
• 1" and 36 mm wrench flats
