BB - common acronym for Bottom Bracket.
Cartridge bearings are very much “fit and forget” units which work until the bearing fails, at which point it will need replacement. Some more expensive cartridge units do allow you to work on the bearings within them, but generally units are designed to be simply thrown away and replaced.The seals on these bearings keep out water and contaminants very effectively - which ultimately means more time riding and less time degreasing!
WORKSHOP TIP: If replacing the more expensive Cartridge bearings, you can find the number of the bearing on the black bearing seal. Internet searches or a good bearing supplier will hopefully be able to find a replacement part.
For information about removal and installation of cartridge BBs, see BB Tasks.
