The length of a bike’s stem, which is the component that connects the handlebars to the steerer tube of the fork, plays a significant role in determining the handling characteristics of a bicycle. While many factors contribute to bike handling, such as frame geometry, wheelbase, and fork rake, the stem length specifically influences how the rider’s weight is distributed over the front wheel, the responsiveness of steering inputs, and overall stability. In this comprehensive guide, we will explore the various aspects of how stem length affects bike handling, including the physics behind it, practical considerations, and the impact on different styles of riding.
