Alloy or Carbon Steapost?

I need an inline seatpost and I have been recommended:
A syntace p6 (carbon) which I can't find anywhere or a
Thomson alloy seatpost
I'm happy to consider any seatpost as long as it doesn't come at much over £100 though obviously would like to spend a lot less.
It will be going on a carbon framed bike and if it works well I will fit the same on my titanium bike as well.
It has been suggested to me that there is very little difference between an alloy and carbon seatpost as regards comfort. Would you agree or disagree and why would you go for carbon in that case? Weight I presume?

If you want a light non-seatback seatpost, the lightest are alloy
Carbon seatposts might take a bit of the road buzz, but it was unnoticeable to me when I changed - it's all about tyre pressures anyway...
From Wiggle your best choice of a light weight non-setback post is the Thomson Masterpiece:

Thomson are an excellent company who make very good quality products. The only reason I have a carbon post on my best road bike is aesthetics. I have a Thomson post on my MTB and will eventually get one for my second bike.0

How much post do you have showing ? If its only a bit then carbon v alloy isnt going to be much difference.
How does your carbon bike ride anyway - if its stiff then yeah try a carbon post too - if its a comfy ride, then you prob dont need any more carbon ?0 -
I've used a few and the 'firmer' carbon posts are very similar to, say, a Thomson Elite.
But the 'softer' carbon posts definitley have more give IMO. For example, a Spesh Pave.
I'm currently running a EC70 which is firmer that he Pave but close to the Thomson. As said, it does depend on how much is showing for this effect.
I'd have a look at the masterpiece (maybe s/hand), and the inline EC70

Having had a few carbon posts and now gone back to Ally because I could not get rid of a persistant creak from the latest CF I can honestly say there is no way I could tell whether I was using a carbon, ally or even steel seatpost. They are only a stick to hold the saddle up after all, and I would agree with reddragon that tyres and pressures are the defining thing with comfort.0

tried them all I think and v.little difference between them. What's more important is good adjustment and longevity. Currently use a Thomson Masterpiece (expensive compared to the regular Thomson and not worth the extra), a couple of regular Thomsons and an Easton EC90. The USE Alien Sumo looks OK and uses a single bolt adjustment. I also have a generic carbon post labelled 'Outland' which is fine (it uses the standard two bolt clamping system)M.Rushton0 -
Thomsom gets my vote. Easy set up and adjustment. Sturdy as can be. I could not get past the paranoia that the carbon one I had(which worked fine) was going to break.
Had 3 friends whose carbon posts broke. Like I've said before "who needs or wants to worry about a seat post breaking".

OK,
I think we have near enough as consensus as I have ever seen on a forum then :shock:
Is there much of the seatpost showing? Depends what much means however on both bikes they are nearer the top of the number scales than they are the bottom so I guess that means more in than out so alloy should do the job very well.
So it looks its going to be a Thompson. Just have to do the will I or won't I get the masterpiece

Ok decided on Thompson Elite as I will be getting 2 of these eventually so I can always get the masterpiece if this helps sort my saddle area probs
I need a 27.2mm post however not sure what size to get.
My current seapost on the bike I will be using this on has about 135mm of exposed post.
I can get 250mm, 330mm or 410mm seatposts. Not sure what the minimum insertion height is on these posts so would I better to play it safe and go for the 330mm. I presume how much is actually inserted into the seat tube isn't that important so long as it goes beyond the minimum so I presume the only hinderance to it would likely be the top cage bolt and I've measure from the top of it to the top of the seatpost at is about 410mm so look like a 330mm would be the way to go. 410mm would give no wiggle room and 250mm may leave me struggling to meet the minimum insertion point.
Have I answered my own question? 0 -
The Elite is so damn fine I can't see why the Masterpiece is worth the premium...0

If you had seen the cut of me trying to cut a threaded screw down for a diy fork spacer which I needed for my bike before bagging the bike for air travel. It took me 20 mins. Worked a treat though 0
