Do those bars serve a special purpose or are they just another set of bars? I guess what I am asking is are they built specifically for a certain riding style?
They are handlebars for a bike. Road style bike. The purpose today is they are for the older, slower long distance rider. Randonneur is a long distance riding style. If you look at the historical (40s 50s) pictures of European bicycle racers, you will often see flared handlebars on their bikes. And more upright riding positions with stems showing. The tiny bike with the seat as high as possible and the bars as low as possible is a newer look. In olden times the racers raced 100+ miles everyday for 8 months on less than smooth roads. Sometimes dirt or gravel roads. So having a comfortable bike was more important than a super aerodynamic bike.
