Description

A precision CNC-machined aluminum tool for the installation and removal of select components with 16-notch tool fittings, including bottom brackets, center lock disc brakes, and e-bike motor lockrings. Manufactured in-house by Park Tool, anodized for easy identification and featuring a ratchet/torque wrench-compatible 3/8" drive. 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 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. The BBT-69.4 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: Confused by what bottom bracket tool you need? You're not alone. Between all the standards, installation methods, and tool fittings, it can all seem a bit overwhelming. Whatever you do need, Park Tool makes over 40 different tools to aid in the removal and installation of bottom brackets. Here's how to determine the correct tool for you, if you have an threaded or thread-together bottom bracket: Remove the crank and inspect the bottom bracket shell for tool fittings, which can be notches or indentations on the outer perimeter, splines on the inside perimeter, or pin holes on the face. Count the number of tool fittings on the cup. Next use a caliper to measure the diameter or width of the tool fittings. For external notches, simply measure the outer diameter of the bottom bracket cup or adapter. Take the measurement in millimeters. The BBT-69.3 is for 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. Here are some tools we offer for this and a few similar tool fittings: Since our origins in the back of a bike shop in 1963, it has been Park Tool's sole mission to design and manufacture high-quality tools that empower mechanics and riders of all skill levels to service their bicycles. Just like our other 500+ tools, our bottom bracket tools are a product of our decades of experience and expertise in the industry, in the shop and on the trail.

Nice tool to have in your tool box
Perfect tool for outer lock ring for disc brake rotors...fits perfectly snug onto the ring.

It's made by Park - what's not to like?
I have not used this on a bottom bracket, but I used it to remove and install Shimano center lock brake rotors on a new set of carbon wheels and it worked flawlessly. I'd never performed this task prior to using this tool, but had no problems at all. Precise and snug fit between the tool and the notches in the rotor lock ring. My only question is why it's also described as a pedal tool. Not sure how it would be used to remove/install pedals. ... show more

Works very nicely
Splines securely engage the notches on the threaded BSA bottom bracket. I allows removal and installation without marring the BB. Different threaded BSA bottom brackets have different diameters and number of notches, so be sure to get the correct tool for the job. I needed two different ones, one to remove the old BB and one to install the new one. ... show more

Great Tool
Good tool to have for working on bottom brackets. Need to have to do the job properly. Good deal and fast delivery!

Tricky for a stuck centerlock ring.
EDIT: If what you are removing is stuck make sure you have a lot of leverage (long breaker bar for example). I finally got it to work but not without the aluminum on this tool getting torn up a little. Original review: I tried using this on my centerlock rotor lockring. It probably works fine if it isn’t stuck, but mine is stuck, and there is no way I can find for this to get enough grip when the torque is off-plane from the ring. The aluminum teeth are now pretty shredded because it slips off too easily no matter how hard I try to keep it on. A wrench that is inline with the ring will hopefully work better. It’s unfortunate because I’m normally a big fan of Park Tools. ... show more

Works for MT501 Bottom Bracket
This is compatible with MT501 bottom bracket in case you were wondering, i could not find a positive confirmation anywhere and took a chance buying this. So in case you are looking, here it is - works with MT501 BB i just installed it.

Expensive but they work so it’s worth it.
I like good tools, I love good tools made in the USA. Park tools are expensive, but they are precision made, fit right and are easy to use. Park engineers are pretty sharp in my book.

Park tool is the tool
You can never go wrong with Park Tool. I used for the lock ring on my disk rotor. Great fit.
