Stem

关于

The stem is the component that connects the handlebar to the steerer tube of the fork , playing a key role in a bike’s steering , handling , and rider position . Stems come in various lengths , angles , and materials , allowing riders to fine-tune their fit and ride feel . A carbon stem is especially popular for its lightweight , stiffness , and ability to reduce road vibrations , making it ideal for performance-focused road and mountain bikes. A properly chosen bike stem improves comfort , control , and efficiency , whether you’re riding aggressively on trails or seeking aerodynamic advantage on the road.
