The present disclosure relates to a handle structure, and more particularly to a bicycle handlebar assembly.
National healthy activities have been deeply rooted in mind and spread to the whole society. Bicycle is one of the popular sports. Riding bicycle is not only a healthy activity but also a means to make a grand tour.
To satisfy various requirements, such as traffic, short trip, racing, long-term trip, ironman triathlon, the handles of bicycles have various types. In addition to general flat bars and drop handles, aero handlebars, extension handle bar or other handles of various types and functions are also popular in recent years so that bicycle riders may enjoy the riding as possible as they can with various handles.
For aero handlebars which are frequently seen in riding activities, the aero handlebar is often combined with an extension handle bar for high energy-consumption sport such as ironman triathlon. Since the combination of the aero handlebar and the extension handle bar makes the drop to be a constant and not adjustable. The term “drop” means the height difference between the grip portion of the handle bar and a stem.
In addition, the width of a conventional handle is not adjustable, either. A handle is not necessary to fit all riders. The rider not suitable for the handle due to body size needs to replace the handle with a new one fitting his/her body size.
