I though I would post links to these two seatpost tests, testing flex and damping. Theres a lot of marketing BS about seatposts out there, so to see some actual testing is awesome. For instance everyone says titanium seatposts are better than carbon for flex/damping. Velo news tested Moots titanium seatposts, and they are not good at all. Also the Specialized CGR looks like a good seatpost (even though it is ugly). But in actual testing it actually doesn't really work much at all.

Then you need to click the link to the bike radar review above. It has the Ergon CF3 and the Syntace Hiflex (the Niner is just a rebranded Syntace Hiflex).
