Adding a carbon seatpost

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Adding a carbon seatpost

I am thinking of changing out the stock seatpost on my Klein (Bontrager Sport) for a carbon seatpost. I have been thinking about the Specialized Pave as I liked it on the Roubaix I rode. Is this a good investment of $100 and what are some recommendations on posts. I don't know much about them.

Thanks.

It's a good investment. I recommend one from either Deda or Easton. You can get a look at both names at competitivecyclist.com and actually they have a sell on an easton for $89 http://www.competitivecyclist.com/za...&MODE=SPECIALS
Between the two if you spend the money I like the Deda Blackstick.
Also check ebay for carbon seatposts, many people take the post that came with their bike off and sale it as they may already have a post they like. I'm bidding on one right now...wait maybe I shouldn't have told you that. Outbid me and I'll have to kill you. heh.

Go with Easton. It is hands down one of the best carbon posts on the market. I ride the EA-70 and absolutely love it. Go to the Easton bike website and it will give you all the features, specs and a cool download on how they stress test their carbon products.

Waste of money unless you have a crap load sticking out or its just for looks.

I don't real removing weight is ever a waste of money. $100 isn't that much, but you're right - you won't feel the weight difference, but when I added my carbon seat post I could definitely FEEL a slightly smoother ride. Obviously my road bike is still a pretty harsh ride, but it added a bit of shock absorbing.

exactly, having a carbon seatpost is not just about losing a few grams of weight, but it also dampens the ride more than an alu post. And they have looks to boot.

G'day,

why would you worry about a 'few grams' on a 6-13???....many acrbon posts are no lighter than there ALu equivilants...If you want it for the ride, or the panache, or any other reason...go for it...but the weight savings are so minimal as to not make any difference whatsoever!.....but hey....if the manufacturer has convinced you otherwise...more power to 'em...its your money,

cheers,

hitchy

hitchy, are you sure you're spelling your name right? ;^)

toss-up: how much post should be showing for it to make a good comfort difference? i have 11.5cm (or 4.5") on my bike right now. but then since i got a steel frame i probably wouldn't benefit as much as somebody riding a Dale or something.

Agree. I am using Ritchey WCS post. The saddle angle is "free" adjustment. You can set ANY angle you want. Weight? It weights about 210g. A carbon post is probably under 200g. I used to ride a carbon post but realized that over tightening the seat clamp can crack the post.

Perhaps try a smaller frame?

That's the point. I have an EV3 Alu (no carbon stays) with sloping top tube. It's a stiff mf'er. I also have a EA-70 post and it makes a difference when I'm out for 70+ miles on a Saturday. Weight doesn't matter (as long as it isn't significantly heavier), but comfort adds up.

I switched to the seat post you are considering. The one with the "viscoelastic dampening". Well, if you want it to help reduce weight, great. If you think it will help dampen vibrations.......well, in my opinion it doesn't help any.

Has any manufacturer provided any vibration test data for their carbon components? It would be a straightforward test to measure the so-called vibration damping properties of a carbon stem versus aluminum, steel, or another brand stem. If it really makes a difference, where are the test results?

The same goes for forks, frames, handlebars, etc. If carbon components made a difference, you would think that the manufacturers would be touting how their carbon stuff has more damping than the other guy's stuff.

Larger bike parts like frame and wheels may behind a lot from carbon. I know because I race with a pair of Zipp 303. Seatpost? Stem? Handle bar? Crankarms?? In fact, pros use carbon handle bar and stem because they are stiffer.
