Cannondale C1 Aero 40 V2 Carbon Seatpost | 365mm - 0mm Setback - black

The Cannondale C1 Aero 40 seatpost is available with 0 and 15 mm of offset to support a variety of fit preferences. A fully continuous aero surface gives the seatpost its sleek profile, which matches the design language of the EVO frame and exposes less metal to the wind.

A new barrel nut and thumbwheel system allows for easier access and smoother tilt adjustments. No long noses, no awkward angles - fast, precise adjustment with tools that stay away from the seatpost and saddle rails.

Compatible with Cannondale SuperSix Evo Gen. 5 (2026+).
