Stems come in a variety of lengths, all of which affect your riding position, and are a crucial part of your controls. Nowadays, the majority of stems work with a threadless headset so they clamp straight onto the fork's steerer tube and can't be adjusted for height. Some still use the 'quill' method which offers more adjustability but compromises weight. Shorter stems mean quicker steering but a less aerodynamic and efficient position. Whatever you're looking for, we've got the perfect stem for your cycling requirements.
