Tightwad is right - steel seatposts are more durable than aluminum ones for bending resistance! When I had my cruiser, though, the stock one-inch steel seatpost bent when I extended it high enough to fit me. I then got a stainless-steel, heavy-ga. pipe from the plant, cut it to length, and used that for a few months when it began bending too! I then went to larger-diameter aluminum posts and have had no bending problem since.

The Worksman posts, however, ARE significantly thicker and stronger (but not significantly larger in diameter) than the average cruiser bike seat post. Thick enough to resist my bending them? I don't know - I haven't tried them.
