BOTTOM BRACKET BEARING TOOL SET BB30 PF30 PARK TOOL BBT-30.4

The Park Tool BBT-30.4 is the bottom bracket bearing tool set for press-fit systems with a 30 mm spindle. It removes and installs bearings and cups in most BB30 and PF30 bottom brackets, and is designed for mechanics who want to work on press-fit frames without improvising.

The set includes a BB30 bearing remover that goes through the bottom bracket shell to drive the bearings out in a controlled way, a set of bushings for use with a cup press (such as the HHP-2 or HHP-3, sold separately) to press in new bearings, and a drift. The remover has extra length, so it can also be used in the wider shells of fat bikes.

Where to use the BBT-30.4 bearing tool set

• BB30 and PressFit 30 (PF30) press-fit bottom brackets
• 386EVO, BBright and PF121 systems
• Compatible examples: SRAM PF46, SRAM PF42, Race Face Cinch
• Wide fat bike bottom bracket shells
• Systems with an inner sleeve may not leave enough clearance for the remover: in that case Park Tool recommends the RT-1

Why choose Park Tool BBT-30.4

• One set to remove and install 30 mm bearings and cups
• Through-shell remover that works directly from inside the shell
• Dedicated bushings to press bearings in square with the cup press
• Extra length to work on fat bikes too

Before removing the bearings it is worth cleaning the bottom bracket shell and checking whether the system uses an inner sleeve. During installation, the kit bushings and the press drive the new bearings in straight and square, with no hammer blows that could damage the frame seats or the bearing races themselves.

For bearing overhauls and replacements on press-fit frames, the Park Tool BBT-30.4 bottom bracket bearing tool set is the natural companion to the cup press in the workshop.
