A crucial part of your controls, stems come in many different lengths and rises which affect your riding position. These days, most stems work with threadless headsets – meaning they clamp straight on to the fork’s steerer tube and cannot be adjusted for height. Take your pick from 25.4mm stems right up to 35mm stems as well as specialised mtb stems and road bike stems.
Some still use the ‘quill’ method, allowing more adjustability, but with a weight penalty. Browse through our top branded stems, including Specialized stems. Think about what you want, and bear in mind that a shorter stem means quicker steering, but a less efficient and aerodynamic position. Whatever works best for you!
