To carbon fibre seatpost or not carbon fibre seatpost?(8 posts)

Hi All,

I have recently purchased a 2003 Cannondale R600 and I am considering buying a carbon fibre seatpost to improve the ride quality. Not that there anything wrong with the ride of the CAAD 5 frame it is one of the more comfortable aluminium frames out there.

I will also be replacing the current saddle with a Selle Italia Turbomatic 4, as a personal preference.

Is there any benefit in ride quality to be had by changing to a carbon fibre seatpost?

run a search this subject has been discussed many times. While most disagree if it makes any difference, those who claim it does have a good amound of post exposed. I have aero CF seatpost on compact frame and on big hits I can feel it flex/works for me. btw I am not heavy weight ~140lbs.

If you do get a carbon seat post, make sure it comes with a warranty. I think Eastons come with one. I know from personal experience with Campagnolo Customer "Disservice" that Campy does NOT stand behind their Carbon seatpost. I've seen three Campy ones in the last couple of months, all cracked.
Good looks, but no diff in ride qualityjtolleson

that's my assessment. Carbon fiber is a very very stiff material (which is its benefit for, say, shoe soles). It absorbs high frequency vibration, which has made it a popular material for forks and handlebars. Picturing it as a true shock absorber (which is what some folks seem to expect) is a bit of a stretch.

Those having discomfort (doesn't sound like you are) would do better with a ti railed saddle and wider tires.

That being said, I like the looks and am not happy I have one. But with about 3 inches of post showing I can't tell the difference between it and my old aluminum American Classic.

If you're trying to improve comfort, I seriously doubt that a carbon seat post is any more comfortable than other materials. If you want to improve ride quality, try one of the shock-absorbing seat posts. Personally, I can't understand why anyone would buy a carbon post -- they only weigh a few grams (if anything) less than some of the better ti and aluminum posts, and there are lots of reports of people cracking their carbon posts. One of the last things I would want to break on my bike is the seatpost, for obvious reasons. For comparison, a Campy Chorus ti seatpost weighs about 10 grams more than the Record carbon post and costs about half the price.

you have to get one, just to stay on a level playing field! ;o)

Seriously, I have a carbon Record seatpost, with 15cm exposed (compact frame) - I certainly feel a difference and therefore would recommend it. BUT, that is my experience and observation and I am sure people have opposing views.

Thanks for all your replies, you guys. I only have minimal seatpost showing 10cm to 12cm because Cannondale build their frames with an additional lip to hold the seatpost. Also the Cannondale is not a compact frame so I think I might leave the carbon fibre seatpost project. I better get back to work now...
