I am offering this original expander for carbon fork steerers, specifically designed for the Bianchi Oltre range (RC, Pro, Comp). Unlike standard star nuts, this expander is designed to apply uniform internal pressure to the carbon steerer. It serves two vital roles: it acts as an anchor point for the headset compression bolt and structurally reinforces the fork steerer where the stem clamps, thus preventing any risk of crushing the carbon fibers.
