The ST-F01 is one of XLC's best value cycling stems. Milled from 6061 aluminum, the stem is lightweight, weighing 195g and has a short stem length to provide a high-stiffness ride and improved stability when riding challenging terrain. The shorter length keeps the bars closer to your body, which generally leads to a more controlled riding experience. The 25° stem angle provides lift to raise the handlebars enough for comfortable hand placement, while retaining the compact stem shape that provides the precise control freeriders and downhillers require when riding in the air. . The A-Head stem attaches to the fork with double-tighten Allen screws and fits a standard 1 1/8 headset. Four bolt handlebar clamp fits 31.8mm bars.
