A precision CNC-machined aluminum tool for the installation and removal of select threaded bottom brackets with 16-notch tool fittings, including Shimano® Ultegra® BBR60 and Deore XT® MT-800 bottom brackets. Manufactured in-house by Park Tool, anodized for easy identification and featuring a ratchet/torque wrench-compatible 3/8" drive.

The BBT-59.3 features integrated threads for full compatibility with the Park Tool BBT-RS Bottom Bracket Tool Retaining System (sold separately). The BBT-RS uses an adjustable spring-based tension system to apply consistent, adjustable pressure to the tool, ensuring full engagement with the tool fitting and preventing slippage.
