Has anyone seen one of these? Ebay item 150172279048
It seems to be a short seatpost (or adapter, or extension) with a quick release lever. This piece has a horizontal sleeve at the center which allows the saddle to slide rearward ... while riding. Used by cyclo-tourists for steep ascents or descents.
Never seen anything like this. Interesting idea.
