Pinarello Most Aero Top Cover for Expander Plug

If you are running a Pinarello Gan or F-series frameset and the standard issue expander plug in your fork, this Pinarello Most Aero Top Cover was designed to specifically mate with the shape of the aero design and the expander plug. As these are proprietary designs, you need to have the correct OEM product for replacement.

The Pinarello Most Aero Top Cover for Expander Plug is made from 1K carbon, and kept with a simple matte finish that matches the headset spacers you should be using with this design. You will notice a pin at the rear portion. The pin engages the spacer or stem above to maintain the proper aero alignment of your stack, which turns with the steerer and stem.
