Information
This two-piece tool was designed as a more affordable way to remove 29mm and 30mm bottom bracket bearings from BSA, T47, and PF30 bottom bracket cups. Currently your options are either invest in an elaborate bearing puller and all the appropriate little pieces to fit each specific bearing, or use a screwdriver to knock your bearings out and probably gouge the inside of your cups. This tool does not require any other removal tools beyond either a rubber mallet, a bench vice, or an arbor type press. BSA cups with 29mm or 30mm bearings are notoriously hard to disassemble because there is almost zero clearance between the I.D. of the cup and I.D. of the bearing. But you already knew that, which is why you’re reading this. So invest in the correct tool for the job!
