Other than probably extra strength, and maybe a longer warranty, what advantages or strengths do they offer that normal mid range seat posts don't offer? Sure they allow fine tune adjustments, but don't most seat posts do that anyway and hold the seat there perfectly? I take it that they are more geared for mountain biking, and if used for road its like driving a nail in with a sledgehammer (superior strength), but im seeing more and more road racers show off their Thompson. I'm wanting one on my road and asking myself, "why". And don't tell me that it comes with a little canvas bag, I can get one at the dollar store for....a dollar.
