BBT-49.2 Bottom Bracket Tool
You've been putting off replacing that crunchy, creaking bottom bracket for a while now. Well, you have some downtime on your hands so take the opportunity to go ahead and swap it out. Add Park Tool's Bottom Bracket Tool - BBT-49.2 to your tool arsenal and you'll quickly and easily remove or install 16-notch, 39mm OD external bottom bracket cups such as Shimano's XTR BB93, Dura-Ace BB9000, and other brands like Token.
It's precision CNC machined from aluminum and features updated tooth profiles that interface better with the tool and cup to prevent rocking or marring surfaces. Park Tool anodizes and etches it for easy identification in the toolbox and its 3/8in drive fits ratchets and torque wrenches. This tool is also compatible with Shimano's STEPS square drive motor lockring.
