Park ToolBBT-9 Bottom Bracket Tool(Return to Product Page)

This is perfect for most disc brakes. I have found that some of the older style bottom bracket tools that fit the same lockrings are not deep enough to accommodate the axles on my wheels.

Works great for what it was designed to do.

This bottom bracket tool is a must have if you want to change your bottom bracket, clean hard to reach places, etc. It works great and how you'd expect it to. Grease, oil, and dirt comes right off if your bottom bracket tool (if dirt can come off of my bottom bracket tool because of a dirty bike, they it is certain that it was clean right off of yours).

Great tool to have for DIY maintenance. I have two of the same type of bottom brackets and this one fits both.

Fit my FSB BB replacement as described. It may hang idle in my shop for a couple of years - but it will be there when I need it.

makes it easy to replace the bottom bracket yourself

I used it to install a new set of GXP bearing cups. Simple to use and works perfectly,

The tool fit perfectly to the bottom bracket.

Thanks to the industry for making Campy and Shimano standard. Less tools to loose.

I do all my own bike maintenance on our 4 bikes, 2 road bikes and 2 mountain bikes.

Having the right tool for the job is critical to completing the job without frustration or damaging the bike or yourself. Although I've not yet got around to using this tool all the tools I have purchased from Park are great tools and I would highly recommend Park Tools.

Works! Fits well and easy to use

Park Tool has been making quality tools for a long time. I need this bottom bracket tool in my collection because I'm changing my cranksets several times a year. I have a front double, single and triple I switch in and out for mountain biking, cyclocrossgravel and road style riding. If you like to work on your own bike instead of taking it to your LBS, then this bottom bracket tool pays for itself in probably one use. You can count on the quality of Park Tools.

I picked this up when my mountain bike bottom bracket seized. I figured removing the old bottom bracket wasn't a big deal with vice grips but probably not a great idea for installing the new one. The right tool is always helpful when doing a job and this isn't any exception.

Pulling BBs? Swapping disc rotors (some of them)? This is the tool for you. As with everything they make, Park has done a great job making the best tool for the job. If you don't own this, you probably should.

BB Tool works great. Fits nice and secure.
