Park Tool BBT-10 Shimano Crank-BB Adjusting Cap Tool

Leave it to Park Tool to decide the industry needs a better tool than the manufacterer has produced. The stock Shimano version of this tool is constructed of plastic and will not allow you a great deal of torque without rounding off the edges of the tool with repeated use. In contrast, the BBT-10 is made from investment cast steel and is considered shop quality.

It is designed to remove and install the adjusting caps on Shimano Hollowtech II crank and bottom bracket systems. Both the length of the handles and steel construction provide the strength and leverage needed to remove seized caps as well as installing and removing non-seized caps during standard operation.
