I've been on the lookout for an expanding seatpost for my Vitus Dural 979. The previous seatpost sheared clean through & I stupidly binned it, thinking it would be easy to replace. This seatpost has an allan key bolt running from the top where the seat is secured, right down the middle of the seatpost. When tightened it draws a wedge up inside the seatpost, expanding the seatpost out against the bike frame tube. They are impossible to find. Anybody know where I could buy one?
