A stem is the part that connects the handlebars to the steerer tube of the bicycle fork. Occasionally called a goose neck, stems can have either a quill or threadless design compatible with corresponding headset and fork systems.
In a quill system, the stem inserts into the threaded steerer tube and does not extend above the headset. The newer threadless system's stem clamps around the steerer tube extending above the headrest. These newer stems often require less work in swapping and attaching than the older model.
Despite your best efforts, sometimes the bike you get doesn't have all the technical features you want. We offer lightweight, sturdy and compatible stems to add to your favorite bike. All our products come from quality brands like Profile Design and 3T.
