Two new bottom bracket standards are rapidly gaining acceptance in the bicycle industry. “BB30” and “Shimano Press Fit” (“BB90”) bottom bracket systems allow bearings to be pressed directly into an oversized bottom bracket shell, eliminating the need for threaded bottom bracket cups. The Park Tool BBT-39 Bottom Bracket Bearing Tool Set is designed for installation and removal of the bearings used in these new bottom bracket systems.
