Sealed cartridge bottom brackets are normally two pieces, a unit holding the spindle and bearings that screws into the bottom bracket shell from the drive side and a support cup (often made of light alloy or plastic) that supports the spindle/bearing assembly on the non-drive side.

Other designs are three piece, the spindle is separate, but the bearing cups incorporate cheaply replaceable standard cartridge bearing units.

The term "bracket" refers to the tube fittings that are used to hold frame tubes together in lugged steel frames which also form the shell that contains the spindle and bearings; the term is now used for all frames, bracketed or not.

There is some disagreement as to whether the word axle or spindle should be used in particular contexts.

Many current designs are now using an integrated bottom bracket with outboard bearings.

This is an attempt to address several issues associated with weight and stiffness.One-piece cranks are easily maintained and reliable, but heavy.They are found on BMX bikes as well as low-end road and mountain bikes.Bearing cups are pressed into the bottom bracket shell.The crank holds the cones, facing in; adjustment is made via the left-threaded non-drive side cone.It comprises a standard spindle and bearings in a steel cylinder with a slightly-modified bearing cup at each end.
