LS-136 | 2016 Ci2 Ultegra Di2 6870 11 spd, 3T Orbis II Pro C35, Size M

Ci2 Carbon Road Bike


The Ci2 offers the full suite of aerodynamic frame features from our flagship C1R: An AeroLogic ride-tuned tubeset, aero seat post, and an aerodynamically shrouded water bottle mount. Even the head tube height is optimized to cheat the wind - because we can shape it for speed, unlike a stack of stem spacers.

Our AeroLogic technology uses carefully designed tube shapes and cross sections to minimize wind resistance and maintain stability at high speeds. Compared to a standard road bike, the C-Series frame reduces the power (watts) needed to maintain a given speed by more than 16% across all yaw angles. What’s inside matters, too: The Ci2 is formed with Litespeed’s Reactive Pressure Molding (RPM) construction. RPM eliminates extra material inside the frame, increasing stiffness and durability while reducing weight.
