Casati Carbon Aero seatpost. Carbon fiber/Metallic (Bronze Pearl gel coat) aluminum hardware. Made it Italy! Not brand new but has never been mounted or used. Was gifted to me by a pro rider so it’s likely custom. Unfortunately I don’t have any teardrop frames to use it with at the moment. Casati has some of the best hand layed carbon fiber on the market. I have a carbon frame set from them I love. Ultra smooth finish and ultra light post. 206 grams with mounting hardware. Casati graphics sunken below the gelcoat.

Teardrop Measurements: 1.125” across x 1.625” front to back

Length : 12” +/- .5”

Apologies. Can’t find my calipers to give a more precise measurement. But hopefully that’s enough for you to deduce whether it’s the right one for your use or not.
