Is it possible to rotate this seatpost 180 degrees?

I'm wondering whether this seatpost or any old seatpost can be rotated 180 degrees to put seat further forward. Are only certain seatposts specifically designed to do so? Although the force of my weight upon the doohickey at the top of the seatpost may be coming in at a slightly different angle, I can't imagine this would be outside the realm of what the seatpost was intended to handle.

I've heard that if you do this the entire universe will self destruct. Seriously, if you need to do this then I doubt your bike fits you. Oh yeah, to actually answer your question, it should be fine.

There may be a seat post or two which will work but most won't. The angle of the clamp will be wrong and you won't be able to get your saddle level.

Retro is right - I tried it once with exactly that result.

The detail is marginal, but to me that looks like a reversible seat post. Unlike many seat posts the angle change with a 180 reversal looks like it fits within the range of adjustment of the clamp. Most seat posts don't have the range needed for this. Easy enough to try it and see. Just measure the nose to stem and seat height above the BB center first for reference points. Tri riders pioneered this in order to facilitate the hunched position favored by time trialers and bent forward posts catering to tri setups are around.

Checkout the Thomson Elite seatpost. It goes straightup without the common "setback"

I seem to remember that even Thompson clamps have a front and a back.

Profile makes a seatpost called the "Fast Forward" which is intended for triathalon use. It's angled toward the front to give the effect of a steeper angle seat tube on a regular road frame.
