Drop handlebars are the most popular among the fixie community. The advantage of the drop handlebar is that you can hold them in two different ways. If you hold the lower side of the bar, you get better aerodynamics. To ride in a relaxed position, you can hold it like a straight bar. Riser bars, on the other hand, is the second most popular. Riser bars provide great control over the bicycle. It is the favourite among trail riders and mountain bikers. Overall, there is no one handlebar that is better than the others. You should choose one that fits your preferences and riding style.
