Does the seatpost matter?

I tend to think carbon fiber seatposts are more about weight savings than ride quality.

They do actually make a difference. When I built up my rain bike I ordered a carbon seat post that took a while to come in. While I was waiting for it I had a aluminum one and the ride on that was definitely more harsh. The carbon post smoothed out the buzzies and the bumps a lot.

I will try switching them out. I actually think I prefer my old seat too. Now I need to figure out what micro adjust means

AKA "infinitely adjustable," unlike the splined ones, which have basically two or three usable tilts and nothing in between unless you shim them.

Good to know. Thanks.

IMO, yes, it does matter. I won't use anything that's not a 2-bolt micro adjust seatpost. (Ok, I exaggerate slightly....but not by much ) Two bolts make adjusting tilt/pitch much easier, and I'm willing to trade off saddle swapping ease for pitch adjustment.

For aluminum, I like Thomson. For carbon, Easton is my choice.

+1.
But, remember that in theory - to be able to absorb vibrations effectively, the carbon shaft must be free, not inside the seat tube. So it does really make a difference whether your setup allows only a handful of seatpost to show, or several inches of seatpost are visible atop of the seat tube (greater vibration dampening effect)...

I rode on my carbon seatpost today. Too lazy to really get a good idea if it mattered b/c I left my favorite saddle on there. I definitely notice an improvement in vibrations but I would really need to test apples to apples with the favorite saddle and both seat posts!
