Featherlight, with minimal air resistance and a wealth of racing DNA – this bike is built for extreme speed! There's no doubt about it: this bike is all about speed, speed, and more speed. The Litening AIR C:68X SLT meets UCI regulations in terms of weight and frame design, period. The lightness, aerodynamics, and speed this high-end carbon racer delivers are hard to believe. Not only do its Newmen Streem Climbing 35/38 Vonoa wheels come with carbon spokes and carbon rims, but the thoughtfully designed tube profiles are exceptional. Every hundredth of a second matters here! The top-quality Shimano Dura-Ace Di2 shifting and braking components (including a power meter) transform every bit of power from your legs into forward momentum efficiently, while ensuring safe braking maneuvers.
