Stems
Stems come in a variety of types and lengths. The two most basic divisions are quill stems for threaded headsets and steerers and threadless stems for all other headset types and threadless steerers. Next, stems are divided by steerer clamp diameter, then handlebar clamp diameter, and finally stem length and angle.
