Bottom Bracket / Lockring Tool - 16-Notch A precision CNC machined aluminium tool for installing and removing certain components with 16-notch tool fittings, including bottom brackets, CenterLock disc brakes, and lockrings for electric bike motors. Manufactured in-house by Park Tool, anodised for easy identification and featuring a 3/8' square compatible with a ratchet/torque wrench. The BBT-69.4 has integrated threads for complete compatibility with the Park Tool BBT-RS bottom bracket tool retention system (sold separately). The BBT-RS uses an adjustable spring tension system to apply constant and adjustable pressure on the tool, ensuring full engagement with the tool fitting and preventing slipping.
