Description Designed to remove and install the bearings and bearing units used in BB86, BB90, BB92, Shimano Press Fit, SRAM Press Fit GXP, Race Face Press Fit and other press fit bottom bracket systems using the 24mm spindle. The BBT-90.3 tool set includes a bearing removal tool, which slides through and expands behind the bearing (like a head cup remover) so it can be tapped out with a hammer.
The BBT-90.3 also includes two installation bushings #668. Use the bushing in conjunction with an HHP-2 or HHP-3 Bearing Cup Press to press the bearings into the frame.

Great bottom bracket tool
Another great park tool for removing bottom bracket bearings. Very easy to use, but be careful to not hit it too hard, otherwise you will shoot a bearing across the garage.

Very good tool
This makes bearing removal easy. It puts a nice even pressure all around the bearing to tap it out without damage to the bearing or the bottom bracket shell.

Makes removing BB90 bearings on Trek road bikes super easy!
I have two Trek road bikes with BB90 bottom bracket bearings. Riding in Portland's rainy weather means these need to get replaced when they go bad. This tool makes their removal super easy.
