We offer two types of our square taper bottom bracket installation tools: Our pro shop tool comes with a handle and is made out of stainless steel. Our portable tool requires using a 22 mm wrench. This tool is unchanged since its original release by us in 1971. So if you already have this tool you do not need to purchase a new one.
We recommend using two of the tools to help ease the installation.
