The Contour is ProTaper's most popular handlebar. Oversized diameter handlebars, without crossbars, were invented and patented by ProTaper in 1991. This design allows the handlebar to flex more and absorb impacts better than conventional bars, offering the rider more comfort and less fatigue without sacrificing bar strength. The Contour Handlebar utilizes a computer-profiled 5mm wall design and is up to 20 percent lighter than other bars, yet up to 40 percent stronger. It is the most affordable way to get your hands on the most sought after handlebar design in the world.
