The stem is one of the most important components for ensuring you get a comfortable position on your bicycle. Too stretched-out or too upright and you'll likely feel uncomfortable. The same goes for a stem that positions the handlebars too low. In this section, you'll find stems of a variety of lengths and angles as well as those that have a variable position. When buying a stem, be careful to choose the right clamp diameter, the right length, angle and steerer tube diameter. We also sell stems for threaded steerer tubes, commonly found on older bicycles: these are also known as quill stems.
