CARBON SEAT POST

Ron Castia

2004-06-04



You are not going to notice a signficant difference unless you are

running a compact geometry. Classic geometry does not expose enough

seatpost to allow the seatpost to do what it is designed to do.



I have a Titus Drop U (extremely compact) and a Fort Airplane, and I

have tested titanium, aluminum and Easton carbon posts on these bikes.

The best ride was from the Easton carbon post followed by the Titanium.

mine,

Another thing you could try is running your tires 5psi lower than the

max

(if you ride them inflated at max).

This problem is rather common with carbon fibre seat posts. If you put a

small amount of valve grinding compund on the post the fine grit will

prevent slippage.

   I just chucked my Carbon Post and switched to a Thompson AL. The only

reason I changed is that I could not get the Carbon Post to stay in the

frame. It always slipped down, I guess it is a common occurrence, I talked

to several people that had the same issue. Keep in mind that I only have

dealt with one brand of post on one brand of bike. I tried two different

posts from brand "S" with the same results.



As for ride quality, I can?t say that I can tell much of a difference.

Sorry - that was to read "Maybe carbon post benefits can be felt by a very

experienced or sensitive butt, but having put one on a CAAD3 Cannondale some

time ago. . . "

hi all

but then why would we have carbon set tubes?

i run a aero carbon set post in my AL TT bike and i feel the carbon

posts cuts out alot of vibration!

I use a Thomson layback post to torture my "compact" frame Giant into a

configuration that comes close to fitting my non compact 6'3" frame. A side

benefit is a slight suspension effect.

Secondly I just have to point out that "dampening" is what happens when you

ride in the rain. "damping" is controlling vibration.

I've ridden aluminum, carbon and titanium seatposts in

aluminum, carbon an steel bikes. I've found that the

carbon seatposts offer only minimal vibration

dampening over aluminum. In comparison, I think

titanium seatposts give dramatically more vibration

damping.

I also have a stiff aluminum bike (Cannondale) and I purchased a carbon

fiber post to see if it would help. I would say yes, it does help cut down

on some of the vibration, but not a whole lot of it. It's not going to give

any suspension effect, but it seems like when I ride on rough roads, like

the first half of Pumpkin Ridge, it did help a wee bit.

Although I do not have an engineering degree I talk to a lot of them and

have worked on solving problems with vibration dampening and have a good

background in composites. Vibration dampening depends upon canceling out

the frequency of the vibration. Carbon seat posts as well as most long

fiber reinforced plastics, have some very interesting properties with regard

to sound reflection and attenuation.   I think the carbon seat post is a

good idea to try. You have a lot more going on than just a simple problem

of compression loading. However, please keep in mind I prefer to ride on

steel and only have been dragged kicking and screaming into a set of carbon

race wheels.

No, I do not believe you will see any vibration dampening. A seat post only

sees compression forces. Carbon gives dampening in bending as with frames

and forks.

Sorry - that was to read "Maybe carbon post benefits can be felt by a very experienced or sensitive butt, but having put one on a CAAD3 Cannondale some time ago. . . "

Carbon seat stays do offer a dampening effect, for sure. ?The bending or torsional benefit of carbon is in play there. ?Carbon seat posts offer weight benefits. ?Maybe carbon post benefits can be felt by a very experienced or sensitive butt, but not having put one on a CAAD3 Cannondale some time ago and now on my Trek 2200 "rain" bike, I found my posterior does not feel a bit better. ?My carbon-framed 5500 is a different story altogether - with an aluminum post.

hi all

but then why would we have carbon set tubes?

i run a aero carbon set post in my AL TT bike and i feel the carbon

posts cuts out alot of vibration!
