Carbon Fiber seatposts, better than AL?(11 posts)

Carbon Fiber seatposts, better than AL?Bruno S

I need a new seatpost and was thinking to buy a carbon fiber one. Would it help the ride, as the carbon fork does? Easton makes one that looks very good but its more expensive than an aluminium one. I would like to know if its worth it.

Carbon posts do help tremendously with ride comfort. I have the mike burrows designed post that came with my giant tcr, and i can actually feel it flex a little on big potholes. I love it. You can find burrows seatposts used for around $50 in the classified section. As for the easton, great post with the worst clamp design of all time. I had one on my mountain bike, and it wouldn't hold the seat rails tight enough to keep it from shifting full aft while riding. They sent me the upgraded clamp kit with bigger bolts, and it still didn't help. They ended up refunding my money at SuperGo with an RMA number from easton. You might also look at the USE Alien post. It is the lightest post, and it works pretty good too.
Easton was my choice, I can't use Alien because...Bruno S

its too short. my new frame has compact geometry like the Giant so I need a 350 mm post. Easton has 350mm model for mountain bikes. I've read in the reviews that it has problems with tha clamp. I may still give it a try, if it doesn't work I can always return it.

I went to an LBS that carries Giant and saw them. I will get one of those. About the flex, it seems that it would flex from side to side. I don't see how can it flex up and down since in that direction the cross section of the seatpost is very long.

I've got about 1000 miles on my Easton post with no problems at all. The clamps make adjustments much easier and more precise.

Yes, using the Easton seatpost here on a Raleigh R600 2000. I am a light person, 135 lb. The seatpost posts no problems to me. You shouldn't grease the post and should clean up all the grease inside the seat tube before inserting. The seat clamp seems to hold very well. I am a roadies so I don't slam myself against the saddle.

I replaced my Thomson with the U.S.E carbon post, I was able to save some weight, but as far as comfort goes I feel no difference.

I was able to convince myself that I needed a carbon post,bill

and I'm sure that you can, too.
Having used a Wound-Up now for about a year, however, I now have become thoroughly convinced, along with others who seem to know more about materials than I, that there is no difference in feel. It probably depends a little on how much post is exposed, and, if you have a compact frame with miles of post exposed, the potential is there for some flex, maybe, but for the average exposure of 8-10 cm of post, it just isn't going to make a difference.
They're light, though, and they look really cool, which are the better reasons to get them, IMHO.
But I really, really need it...Bruno S

I need a seat post, it doesn't have to be carbon but I have some extra money. My frame broke last week and its being replaced with a compact geometry frame. The old one had the seat post exposed about 14cm. I think the frame was small for me but the top tube was ok. With the new geometry the seat post will need to be much longer (5-7 cm) and the old seat post will not be long enough. Carbon will save some weight and look better so why not? In addition the aero models make the bike look better, IMHO. I just wanted to know if there was any added benefit to the feel of the bike.
