The Bontrager Round Seat Mast Cap is a spare mast cap for Trek road bikes with a round seatpost. These are road bikes on which the seatpost doesn't 'disappear' into the frame, but instead slides over a round seat mast. This seat mast is made of a light carbon construction and has an aluminium seat post clamp.
