        Overview

        D-Lightful

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

        Highlights

        • A fully continuous aero surface gives the post its refined profile, matching the EVO frame design language and leaves less hardware in the wind.
        • 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.
        • Titanium saddle-clamp hardware saves 10g versus steel. It adds a small flash of raw metal where it counts, tying into the LAB71 and Hi-Mod material story.
        • Compatible with SuperSix EVO Gen 4 and Gen 5
        Forward-First Fit

        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.

        Dialed-In Adjustments

        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.

        Clean Aero Profile

        A fully continuous aero surface gives the post its refined profile, matching the EVO frame design language and leaves less hardware in the wind.

        Titanium Touches

        Titanium saddle-clamp hardware on top models keeps grams in check. It adds a small flash of raw metal to show off its technical lightweight design.
