A cup and cone hub makes use of loose ball bearings and allows you to easily adjust bearing tension, unlike most nsk bearing hubs that don't allow for any adjustment. They consist of the "cup" that acts as the bearing's outer race, which is pressed into the hub shell and not replaceable, and the "cone" that serves as the inner race and threads onto the axle. The hub bearings, which are usually 1/4" in rear hubs and 3/16" in front hubs, spin between the cup and cone. Bearing tension is adjusted be threading the cone down on the axle, and then locking its position in place with the locknut (a spacer between the cone and locknut allows you to tighten the two against each other easily). Front cup and cone hubs are usually symmetrical, although the hub will be offset slightly to compensate for its rotor disc rotor mounting. Rear hubs use a freehub (the clutch mechanism that allows you to coast) and the driveside cone and locknut can be found set within, sometimes hidden from view.

At the risk of talking down to some readers and over the head of others I feel the need to explain the term “bottom bracket”. According to Sheldon Brown’s Bicycle Glossary a bottom bracket is:The part of the frame around which the pedal cranks revolve, also the ina bearings and axle assembly that runs through the bottom bracket shell of the frame.
