Whether in competition or during intense training, every hundredth of a second matters for speed enthusiasts. That's why we present our Litening AERO C:68X Race with a UCI-compliant and extremely aerodynamic frame designed to reduce air resistance by 30%. It features a Shimano Ultegra crankset equipped with a built-in 4iiii dual-sided power meter that tracks all essential performance metrics. We've fitted Newmen Streem Allround 49/54 wheels with an aerodynamic profile, mounted with 28 mm Continental Grand Prix tires that are tubeless-ready. The Shimano Ultegra Di2 2x12-speed drivetrain not only offers a wide gear range but also boasts exceptional reliability. The hydraulic Ultegra disc brakes from Shimano provide even more speed by allowing for later braking. Undoubtedly, this is a fast—no, an extremely fast—bike!
