“Thanks, I appreciate the actual numbers but in real world terms and effect, compared to the amount of movement in saddle flex, padding clothing, skin and muscle: sweet FA.”
They’re not actual numbers and once you include dynamic loading and the big horizontal component of forces when you hit bumps, there’s no doubt that a small diameter “rigid” post will reduce a useful amount of the impacts and vibration. Any benefits are in addition to absorption from everything else.
The usual suspects here will insist that the benefits of frame and post (and wheel) flex are negligible but they’re just proving they have a poor understanding of the subtleties of engineering and the sensitivity of humans to tiny improvements.
I’d still rather have a dropper post though!
