This basic tutorial will demonstrate the workings of a typical bicycle threaded head tube set, showing the removal and installation of the various components that make up a head tube set. Although there are slight size differences between different manufacturers, the basic principles of operation and assembly are virtually the same.

Figure 2

A bicycle head tube set consists of several bearing components that allow the forks to spin freely inside the head tube with minimal friction. These parts include: the head tube shell, a fork mounted bearing race, a pair of head tube cups, two ball bearings, a threaded bearing race, and several locking nuts and washers.
