Hi all,

I am planning on raising the stem on my vintage ten speed racer to make for a more comfortable position . The stem has no mark on it that shows the max height it can safely be raise to . I have googled and have been told that 2 inches or 1.5 inches or as long as the expander is completely in the steerer . I was wondering what people with experience think ? as I don't want to cycle with the fear of the stem snapping off mid ride .

Thanks in advance
