Carbon Seat Posts?

I am by no means a weight wennie but i was considering upgrading to a carbon seat post. Does it make a difference in the ride of the bike at all?

I haven't been able to tell myself. I've switched seatposts on my cross bike from the main post which is carbon to an aluminum one in order to add a large seatpost bag for needing to carry more items and haven't felt any difference. The bike I do this on has 28's, is titanium and uses a Brooks Swift saddle so it very well may depend on quite a few factors if you'd notice it or not.

Are you racing? If so, would you trust a carbon post given the stresses of racing?

yea i am planing on racing and whats the worst that can happen....don't answer that. I noticed that my stock seat post is almost a pound so i'm most likely going to something different anyways. the origin 8 one looks good and the price looks good too

I've raced on a kalloy carbon post many times. No problems at all though i doubt it weighs less than a Thomson.

Actually, the saddle did slide back once- but that had to do with the single bolt design I think.

Were I buying a new post where weight was something of a concern i would get a Thomson or a Ritchey WCS aluminum 2 bolt, probably.

I've raced on both carbon posts and a Thomson. The Thomson felt a little stiffer so i stuck with that.

I have seen a carbon post break during a remount, it wan't pretty. The guys finished the race without a seat. hardcore!
