Launched in late 2014, generation 3 BBs feature replaceable bearings

Bearings can be replaced on BSA threaded, PF30 and BB30 bottom brackets

Due to fit constraints BB92 bearings cannot be replaced as the bearing itself presses into the frame

To remove bearings, use a Park Tool headset cup removal tool
-
Slide the tool through the BB cup until it sits on the lip of the bearing
-
Tap the tool to remove the bearing

Remove the bearing and seal from the cup
