Aero handlebars are specialized bicycle handlebars designed to improve aerodynamics and reduce wind resistance for cyclists. They allow riders to adopt a more streamlined position, which can enhance speed and efficiency, especially during time trials or triathlons. These handlebars often feature extensions that enable the rider to rest their forearms while gripping the bars, promoting a lower body position. Typically made from lightweight materials like carbon fiber or aluminum, aero handlebars are adjustable to fit various riding styles and preferences. They are commonly found on racing bikes and are popular among competitive cyclists looking to optimize their performance in events like Ironman or Tour de France.
