The Contour Handlebar is ProTaper’s most popular model. Oversized-diameter handlebars without crossbars were invented and patented by ProTaper in 1991. Without sacrificing strength, this design yields increased flex and impact absorption over conventional handlebars, offering the rider improved comfort and reduced fatigue. With its 2000 series aluminum alloy construction and computer-profiled 5 mm-thick wall design, the Contour Handlebar is up to 20% lighter and 40% stronger than competing handlebars.
