Park Tool Bottom Bracket Tool - BBT-90.3 Info
PressFit bottom brackets demand precision on the way in and on the way out — the Park Tool Bottom Bracket Tool BBT-90.3 is built to handle both without damaging the shell or the bearings. The tool drives out existing bearings by passing through the shell, then uses two included bushings to press fresh bearings into place with controlled, even force. It's designed for 22mm and 24mm spindle PressFit bottom brackets, covering a wide range of current crankset standards.
The two bushings allow you to precisely locate the bearing before pressing, reducing the risk of misalignment that can cause premature wear or creaking — the most common complaint with PressFit systems. This is the kind of tool that makes a fiddly job repeatable and clean rather than a source of frustration.
