Cannondale C1 Aero 40 v2 Seatpost 365mm 0mm Offset 2026 Black

D-Lightful

The C1 Aero 40 seatpost comes in 0 and 15mm offsets to support a wide range of fit preferences.

The 0mm-offset option leans into modern forward-biased fits, bringing the saddle over the pedals. A clean solution for riders who like their position and are ready to sprint.
A new barrel nut and thumb-wheel system enable easier access and smoother tilt changes. No long noses, no awkward angles – fast, accurate setup with tools that stay clear of the post and rails.
