You will need this tool for any of the newer 41mm O.D. bottom brackets; in my case a new Shimano Ultegra BBR60. The tool fits snug to the bottom bracket and allows you to properly torque with a 3/8" drive torque wrench.

not a screaming value but it's extremely well made and had decent purchase on the BBR60 BB. I had to buy this tool because I was transferring my BB to a new frame. I believe a new BBR60 comes with a plastic adapter.

Bought an off-brand version this on AMZ, did not fit, was too tight. Used it to install 105 crankset on Specialized Roubaix.

Review for Park Tool BBT-59 Bottom Bracket Tool
4 of 4 customers found this review helpful.

I bought this to install Shimano Ultegra 6800 and XT8000 bottom bracket cups, which have a unique spline pattern. Like all Park tools, this is a solid piece of work. However, you need a 38 driver to use it, and I'm not sure it works substantially better than the plastic adapters that Shimano ships with their bottom brackets. Overall, this tool is another unitasker that costs more than the component and will be obsolete in 2 years when the component design changes yet again.
