What is a cartridge bb?

A cartridge bottom bracket is a type of bicycle bottom bracket that uses a sealed cartridge bearing unit. The cartridge bearing unit contains the bearings, races, and seals all in a single unit that is pre-assembled and sealed. The cartridge unit is then pressed into the bottom bracket shell of the bike frame, and a threaded retaining ring secures it in place. This design eliminates the need for loose ball bearings and bearing races, simplifying installation and maintenance.

Cartridge bottom brackets are generally considered to be more durable and long-lasting than traditional bottom brackets with loose ball bearings. They also tend to require less maintenance, as the sealed cartridge bearings are less susceptible to dirt, water, and other contaminants. Cartridge bottom brackets come in various sizes and types to fit different bike frames and cranksets. It is important to choose the correct size and type of cartridge bottom bracket for your bike to ensure proper fit and compatibility.
