Hi,
I presently have a 2006 cannondale with a non branded carbon post in 27.2mm which i need to replace as the seat clamp is knackered. i was going to replace with a new carbon post but someone advised me not to put another carbon post in my cannondale as it was of a thin diameter. He stated that carbon posts in cannondales have a bad rep before and recommended aluminium again.
Does anyone know of any other reason for this, and should I replace with another carbon post or aluminium one instead.
I have had a carbon post in my spec for 4 years with no problems but is is a 30.9mm one.
Any help would be appreciated to help me decide.
Cheers all

I don't understand what he means. I can't see a problem! Just take care with fitting ie to grease, not to grease.0

cheers for the reply.
The chap was from a cannondale dealer when i was enquiring about a new post. he said this was the reason why cannondales now have a wider diameter seat tube.0 -
All I can think of was he ment carbon posts are too strong and would cause damage to parts of the thin seat tube, rather than bend or snap like an alloy one. Still doesnt make much sense to me! What about a heavy DH post in there? Carbon posts more likey to shatter anyway!0

Hi again, I only use carbon as i suffer backache from the original aluminium one i had on my spesh. Is aluminium still very harsh as a post.0

Depends on the post. Some carbon ones can be harsh, but they are more likely to absorb high frequency buzz.
Titanium pots are the best for this, as they are light, and flex a bit. Or a sus post?0 -
Would titainium be fine in the thin cannondale tubes then?0
-
Yes. I really don't understand what cannondale are saying here, and why one post would be unsuitable compared to another. They work the same way, and support the same load!0

Apart from USE who else makes a titanium post?0

Maybe the current seatpost is a carbon wrap one, and the guy from the dealer knew this and so was suggesting an aluminum one (which is what the carbon wrap one would be made of) as opposed to a new full carbon one?- Kona Hot '96 - Marin Rift Zone '09 - Cannondale Synapse Carbon '06 - Kona Caldera '98 - Kona AA '94 - Dawes Kickback II - Cannondale BadBoy '11 - Genesis iOiD SS -0

I will ring the cannondale fealer back and ask today.0

I spoke to my cannondale dealer again and this time it was the boss. He told me that what i was told was rubbish and apologised. All he did say was to replace a carbon post every 2-3 years.
