Park Tool Bottom Bracket Bearing Tool Set

The Park Tool BBT-39 Bottom Bracket Bearing Tool Set is for installation and removal of the bearings used in BB30 and Shimano Press-fit (BB90) bottom bracket systems. The BBT-39 includes two bushing sets, which are used in conjunction with a bearing cup press (sold separately), to precisely press the bearings into your bottom bracket shell. The BBT-39 also includes a removal tool for pushing BB30 bearings from the shell (because of the design and light press fit of the bearings, a special removal tool is not needed for the BB90 system).
