The term handlebars includes mostly not only the handlebar itself, but describes the two points of manual contact between the bike and the driver. This assembly influences the perceived driving feeling to a considerable degree. The different fields of application require different demands on ergonomics, damping, control and weight. However, a bicycle handlebar consists of the steering bar and the attachments, like as handles or bar ends. As with all add-on parts, the specific fields of application meet the needs for material and construction of the additional handles.
