I still believe that maybe it does helps slightly but regards to the price for carbon stem, it might not be worth to get it. At first i bought it thinking of adding some blings only but was really surprised that it does helps to lessen the buzz slightly, i would like to point out that the route might not be the most uneven roads around but it have quite a few road humps to slow the cars down thus i can feel lessen buzz when riding through those.
Calnago wrote:Perhaps it lessens the "buzz". I don't know. I just think most of the carbon stems are ugly compared to their aluminum counterparts. As for bars, I have used a lot of gel pads like the fizik stuff underneath the rather thin bartape. Now there are lots of tapes with good cushion in them and I find I don't need the gel anymore. I use aluminum bars as well. Heavier but I found that light carbon bars simply flex too much.
Perhaps the flex helps to lessen the buzz i think.. some friends like stiff and really stiff cockpit whereas some people might prefer some flex in it. i think i am just a casual rider myself thus i prefer some flex in my bike. so far i am still in love with my bike that i am not looking to get newer bikes, at some point i wanted to get a new aero bike but my old look 595 still does the job well, ride smoothly and comfortable whereas the newer bikes i just feel that although it is faster but it is abit "unforgiving" to the rider especially over long distance riding.
But as I said earlier, my carbon LTD stem of which I loved with 20mm of stack underneath on a previous Felt frame - absolutely could not tolerate on my back on a new aero frame, slammed. I suspect if I had 20-30mm of spacers beneath it would feel a bit nicer. But replacing it with an aluminum stem made the front end bearable.

I used a carbon wrapped aluminum stem (Pro Vibe LTD) for over two years and then switched to an Extralite Hyperstem recently and right off the bat I noticed a harsher ride even with the same carbon fork/carbon handlebars. Not sure if it's because of how light the Hyperstem is in comparison (like a 35g difference) or if it's due to the material properties alone.

This is also a good point. If you have a standard round tube steel frame, the vibrations you feel through the stem/handlebars will be more pronounced than if you had a carbon frame, so the subtleties between which stem/bar combination you try will be feel more noticeable than on a different frame.
I know that many a times, people favor the stem made from alloy more than carbon. I am keen to know how many here actually tried and support the use of a carbon stem. Do you find it better as in stiffness/weight/absorb more buzz from uneven road?
In my experience, I don't think it really matters a great deal. There is absolutely no difference in comfort (handlebars yes) and no ascertainable different in stiffness, your handlebars/bar tape direct most of the energy off of the road to your arms, so those are going to have a larger impact than the stem itself.
Bought it second hand in good overall condition for 60 € , so cheap
It weight 129 gr with the titanium screws provided.
It *f##k* stiff as hell but less vibrations are felt than with my alloy one.
I know I am sensible to settings , tubular tires pressure that sort of things
