Stem

The stem connects the handlebars to the bike’s fork and is crucial for adjusting bike handling and fit. Angle affects the handlebar height and reach, influencing riding posture and comfort. Material options include aluminum for strength and affordability, and carbon fiber for reduced weight and improved shock absorption. Length determines how far the handlebars extend from the bike, impacting steering responsiveness and overall fit. Choosing the right stem involves balancing these factors to achieve optimal performance and comfort.
