The Cannondale C1 Aero 40 v2 Seatpost is an aerodynamic, D-shaped road seatpost designed primarily for the SuperSix EVO Gen 4 and Gen 5 frames. Constructed with a continuous aero surface that integrates seamlessly with the EVO frame, it reduces drag by minimizing exposed hardware. The seatpost features a refined barrel nut and thumb-wheel system for smooth, tool-accessible tilt adjustments without interference with the saddle rails.
Available in 0mm offset (K2604500) and 15mm offset (K2604515) options.
This is the titanium clamp hardware version which saves about 10 grams over the steel hardware version. Small silver graphic on the back top of the seatpost differentiates the titanium version.
