Metal was too soft to remove very stuck center lock disc brake retainer nut. Since the metal was soft aluminum, and the grip surface was very thin, this tool did not work great. I needed to use a ton of penetrating oil and an overnight soak. Only then I was able to remove the lock nut, still with a lot of force. However, the soft metal tool was damaged in the process. A harder metal, like steel, would be a better choice for this too. Also, a better was to hold grip onto the thin lock nut. PS: Whomever put the nut on before, obviously put it on too tight. I have now put on a replacement (original was damaged during removal), torqued to the proper spec with a torque wrench. This tool was very useful in using my torque wrench.

Works like a champ! The right tool for the job makes all the difference. The blue anodized color makes it a pretty tool too.

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.

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.

Used it to replace my GPX bottom bracket. I love aluminum tools and this one is no exception.

Used to replace bottom bracket on mountain bike with ease. Park tools are well made and reliable. My son works in a large bike sales/service/repairs wharehouse and they only use Park Tool products. Says it all really. Pay more, get more.

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.
