Comfort, ergonomics, stiffness and aerodynamics are the essential elements of Zipp's amazing Contour SL Handlebar, and every millimeter of this feathery-light 190-gram carbon bar is designed for complete control, all-day comfort and an awesome ride. The airfoil top cheats the wind for free speed, elegantly hides the cables and fits your hands perfectly. Ditto for the oval hook portions and the angled-outward drops that provide superior comfort and ergonomics. And, the SL is plenty stiff to win the sprint after you've been in the break all day. Plus, it feels great mile after mile thanks to Zipp's vibration-damping VCLC technology.
