Park Tool BBT-90.3 bike tools

A quick and easy way to remove bearings from press fit type bottom brackets with an inside diameter of 37-41 mm (BB90, BB92, Shimano Press Fit, SRAM Press Fit GXP)
The BBT-9'00works similar to a small head cup remover to safely extract low profile bearings from inside the bottom bracket shell.
As the tool slides through the shell it expands behind the bearing, once the tool is in place, the bearing is removed by tapping on the top cap with a hammer such as the Park HMR-3
The BBT-90.3 set also includes installation cups to be used in conjunction with the Park Tool HHP-1, 2 or 3 Headset Cup Press to quickly and precisely press the bearings into the bottom bracket shell
