Overview
Does the Park Tool BBT-9 fit Shimano Hollowtech II cups?
The Park Tool BBT-9 is a dedicated installation and removal tool for Shimano Hollowtech II external bottom bracket cups. The splined interface engages the full cup notch pattern for precise torque transfer, preventing the slippage and cup damage that can occur with generic tools or makeshift solutions during bottom bracket service.
Designed for use with a 3/8-inch or 1/2-inch drive ratchet or torque wrench, the BBT-9 makes bottom bracket service fast, clean, and correct. Whether you're installing a fresh drivetrain or pulling a worn BB during a seasonal overhaul, this tool delivers the fit and function Shimano Hollowtech II cups require.
