Bottom Brackets

The bottom bracket (BB) is stored within the bottom bracket shell of the bike frame. Over time, the bearings will wear out and need to be replaced (or serviced).

Ensuring compatibility and choosing the right bottom bracket can be daunting.

Basically there are 2 types; threaded and press-fit bottom brackets.

Threaded bottom brackets thread into the bike's frame. Press-Fit get pressed into the frame.
