Go by the minimum insertion mark on the seat post. 1" is not enough. Usually want it to be in past where the top tube and seat stays intersect the seat tube. Less than that and there won't be enough support. Get a longer tube if possible and make sure you get the right diameter. They come in dozens of diameters and you need to match exactly or you'll have problems.
