The Litening AIR C:68X SLT meets UCI regulations in terms of weight and frame design, but what this high-end carbon racer offers in terms of lightness, aerodynamics, and speed is in a whole different league. Not only are its Newmen Streem Climbing 35/38 Vonoa wheels equipped with carbon spokes and rims, and fitted with 28 mm Conti GP5000 S-TR tires, but the cleverly shaped tube profiles are also in a class of their own. It's all about every hundredth of a second! Additionally, our aerodynamic carbon cockpit saves up to eight watts. Speaking of watts: the highest quality Shimano Dura-Ace Di2 shifting and braking components – including a crankset with power meter – efficiently convert every bit of power from your legs into propulsion and enable safe braking maneuvers. This bike is speed, speed, and more speed.
