The Pinarello Grevil, Grevil+, and Dyodo Gravel bikes all feature an aero carbon seatpost design that is secured by a free floating wedge system that inserts into the toptube, just forward of the post. The design is very clean and wholly effective. If you lose or damage yours, this is the proper and only replacement part that maintains your Pinarello warranty.

The multi-part aluminum wedge comes complete. Always follow the proper torque specification for safe and proper results. Carbon paste can be used inside the seattube if additional friction is desired.
