Park Tool BBT-69.4 Bottom Bracket/Lockring Tool: A Versatile and Reliable Solution

At the heart of any bicycle lies the bottom bracket, and ensuring its proper installation and removal is crucial for the smooth operation of the entire drivetrain. The Park Tool BBT-69.4 is a precision CNC-machined aluminum tool designed to tackle this critical task with ease.

Manufactured in-house by the trusted experts at Park Tool, this tool is anodized for easy identification and features a ratchet/torque wrench-compatible 3/8" drive. Its versatility lies in its ability to handle a wide range of 16-notch tool fittings, including those found on bottom brackets, center lock disc brakes, and e-bike motor lockrings.

The BBT-69.4 is designed to fit 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. This includes a variety of popular bottom bracket standards, such as Shimano BB80, BB5700, XT BB70, and BB51, as well as external bearing threaded cups from Campagnolo, Chris King, FSA MegaExo, Hope, SRAM/Truvativ GXP, Race Face X-type, Surly, Wheels, Fulcrum, and others.

To ensure a secure and consistent engagement with the tool fitting, the BBT-69.4 features integrated threads for full compatibility with the Park Tool BBT-RS Bottom Bracket Tool Retaining System (sold separately). The BBT-RS utilizes an adjustable spring-based tension system to apply consistent, adjustable pressure to the tool, preventing slippage and ensuring a reliable installation or removal.
