aluminum post ride quality & carbon frames

[Mr. SR500]

I've had both carbon and alum seatposts on my carbon frames. No difference at all. If you're looking to save weight if might make a tiny difference, but the Thomson Masterpiece I settled with is as light as most carbon posts.

As mentioned, tires will do a lot more for comfort.

+1 I love my Thomson Masterpiece on my Madone!
