Park Tool BBT-90.3 Bike PressFit Bottom Bracket Bearing Tool Set BB86 BB90 BB92
Dec 19, 2017
This tool worked flawlessly to punch out my BB86 bottom bracket and the included bushings fit the new Shimano BB86 perfectly upon installation.
The park tool punched out the old BB86 with little effort and the included bushings kept the new bottom bracket in alignment as I pressed it in. I bought a 6 inch x 5/8 inch hex bolt with a nut and two washers for under 5 bucks; attached the bushings and pressed the new BB86 with no drama. Cant ask for more from a tool kit.
