C1 Aero 40 v2 Seatpost 365mm

The Cannondale C1 Aero 40 v2 seatpost brings a D-shaped aero profile that follows the seat tube line on SuperSix EVO Gen 4 and Gen 5 frames, keeping hardware tucked away for a clean silhouette. Its continuous surface reduces drag while maintaining the structural cues of Cannondale's road platform, making it a natural replacement part for riders upgrading or repairing their setup.

A barrel nut and thumb-wheel adjustment system allows tilt changes without tools crowding the post or rails, simplifying saddle setup. With 0mm offset and a 365mm length, this post supports a forward-biased position that places the saddle over the pedals, suiting riders who prefer a neutral to aggressive fit on the road.
