Other than adjustability features, does seatpost quality matter? I don't care for the seatpost on my new bike. My other one has little ridges to allow you to "feel" where you are putting the angle of the seat. It is also much easier to trade out saddles. Lastly, it is carbon fiber. Does a carbon fiber seatpost make any impact on quality of ride? I was thinking about seeing if I could trade them out. Or possibly look at a different one for my new bike.
A micro-adjustable seatpost makes more difference than you might think. If you can get the saddle tilt you want without it, great; but unless you have a tensioned leather or uncovered carbon saddle, as it wears in, odds are it will compress unevenly, and micro-adjustability may let you get more life out of your saddle. You can shim a splined seatpost - I do - but the shims compress, too, and it needs to be re-done periodically.
I'd be surprised if there were really a noticeable ride difference between carbon and aluminum, although I've never ridden carbon, so I can't say from personal experience.
Carbon seatposts can be a PITA - I know how easily it scratches because the one that came on my bike is carbon-wrapped. And I've read that carbon has a tendency to slip in the seat tube, and you need a special carbon paste to lubricate it. But that latter is hearsay only.
Still, I'd be hesitant to give up the micro-adjustability. (Trade ya? :p)
I tend to think carbon fiber seatposts are more about weight savings than ride quality. I do agree that some seatposts have clamps that are easier to adjust than others. Beyond that, just make sure you replace the seatpost with one with the right amount of offset for your preferred saddle position vis-a-vis the pedals. I, personally, need a lot of offset, so finding an approprite seatpost is hard.
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.Quote:

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.Quote:

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

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!
