The Park Tool BBT-69.4 is a professional-grade tool for mechanics and serious cyclists needing to install or remove threaded bottom brackets with 16-notch fittings. Its key benefit is precise, secure engagement with a wide range of components, ensuring damage-free service. A minor caveat is that it requires a separate 3/8" drive ratchet or torque wrench for operation. This tool is CNC-machined from aluminum, features a durable anodized finish, and is compatible with major brands like Shimano, SRAM, and Campagnolo, as well as certain disc brake lockrings and Bafang motors.

Yes, you will need a 3/8" drive ratchet or torque wrench to operate the tool. The BBT-RS Bottom Bracket Tool Retaining System is also optional but recommended for a more secure fit.
Yes, the BBT-69.4 is also compatible with many 16-notch disc brake rotor lockrings.
It fits 16-notch fittings with a major diameter of 44–45 mm and a minor diameter of 42.7 mm.
The tool comes with a 12-month warranty.
No, this tool is specifically designed for threaded bottom brackets with 16-notch fittings and is not compatible with press-fit systems.
Ensure the bottom bracket has a 16-notch fitting and that the tool's major diameter (44-45mm) and minor diameter (42.7mm) match the lockring. Confirm it is not a different notch count or a press-fit style bottom bracket.
Clean both the tool's notches and the bottom bracket lockring thoroughly. For best results, use the Park Tool BBT-RS Bottom Bracket Tool Retaining System (sold separately) to secure the tool to the bottom bracket.
Ensure the correct drive tool (ratchet or torque wrench) is firmly engaged. Apply steady, controlled force. If extremely tight, a penetrating lubricant applied to the threads (if accessible and appropriate for the frame material) might help. Always use a torque wrench for reinstallation to the correct specifications.
Clean the tool and the bottom bracket lockring. Check for any debris or damage to the notches. Ensure the tool is properly aligned and not cross-threaded.
