seatpost: aluminum or carbon?(6 posts)

seatpost: aluminum or carbon?Muskrat

I have a new CAAD7. Will a carbon seatpost really remove much road vibration? I had an aluminum seatpost on my CAAD5 and it seemed fine. Is it just hype or will the ride be noticeably different? Better or just different?

Thank you.
I doubt you'd notice much difference.Spoke Wrench

Think about the amount of travel you get from parts like the seat rails and the suspension of the seat itself. Now think about how much travel you'd expect from 6 or 8 inches of exposed carbon seatpost.
No real differenceKerry

Unless you have a lot of seat post exposed, you'll be hard pressed to tell the difference between a CF and Al post. There are many other factors about which you should be much more concerned, primarily the design/quality of the clamping mechanism.

It's not about deflection (unless maybe you're riding a compact frame w/ tons of post showing), it's about the ability of the material to dampen vibrations, which carbon fiber does well. i've had an easton ct-2 carbon post on my bike for a couple months now and there is definitely a difference in the amount of road "buzz" i feel in the rear. I was skeptical when i purchased the post as to how much of a difference it would make in ride quality (i was more interested in the weight savings), but was surpised to find it improved the ride. It's not like riding on a full suspension or anything, but you can feel the difference.

This topic has been discussed here extensively, and the VAST majority of people who have made the switch say they can tell no difference whatsoever between an Al or CF seat post.

Let me call your attention to the 'best carbon seatpost' topic one page on. My conclusion: carbon has not evolved enough to guarantee years of trouble-free abuse in a seatpost. Aluminium alloy has.
