The AeroForce CNT Clip-On Bars are extremely light, stiff and strong. In fact, they're among the lightest and stiffest clip-ons on the market thanks to the carbon-monocoque construction. Plus, the pad width is easily adjusted for comfort on any course, too, and the cantilevered pad support arms absorb shock for comfort.
