So, not sure how manufacturers weight their stems, guess we can't expect bolts to be included, but faceplate, yes I would think.
Switched to Shimano Pro Vibe UD Carbon stem 110mm, and Vibe Compact Bars, 42cm C-C. Haven't got the bars yet, will weigh those, but the weight of the Shimano is right on target, if you don't have the faceplate or bolts. Hmm....
110mm Box says 115g
Which is the size I received.
Actual weights.
Stem, no faceplate or bolts:
Stem faceplate:
Stem bolts:
Entire Stem/Faceplate/Bolts:
And now the Bars....
Box says 195g, since they don't specify, going to have to assume 40mm bars, mine are 42mm C-C
Drum roll please.....
Not too far off, and maybe they didn't specify size anywhere I can see. And, their site says 190g, and that doesn't specify compact, ergo or round.
Considering the box weighed 299g it came in, can't complain too much.

Off by nearly 20%..........!!
Maybe Deda is making them on contract
20% would make a 1000g frame now 1200..............

So it's just carbon wrapped aluminium?
Oddly enough, I thought that the actual weight (as you verified) was exactly as one would expect from the "PRO" line. Why would they even suggest it is lighter than what it actually is?
(also: too heavy.)

My PRO Vibe Thor Hushovd editions were 132 for the 110mm and 137 for the 120mm ... I found the weights respectable for the size and stiffness.

Don't get me wrong, I love these stems, use to have a Vibe 7s. -10 degree, definitely stiff. Puzzle setup works really well, simple. But I was a bit surprised about the weight, but according to you guys, seems to be the norm and overall weight based on experiences.
I'm not whining over a few grams, isn't going to make a difference in a race, but just found it interesting how far it is off, unless you don't include the faceplate/bolts, then dead on.
You know that is funny, because the other option for my new cockpit/color setup I was looking at the Deda Superleggero stem -8, and their Presa compact bars as a combo. They have that stem listed at 99g for the 110mm...which I find hard to believe. The 42mm Presa bar is listed at 214g, which could be reality and normal.

Do you still have the package? I seem to remember it saying something like "from" or "for 100mm" for the stated 115g weight. I was a bit disapointed too...
But not unlike Cannondale stating an "average" weight for an Evo in size that doesn't exist. Still wrong tho

Nah...it's pretty clear what they are referring to.
I feel your pain with Shimano. I bought a set of DA level shimano wheels, they came in about 150grams over claimed weight, close to 10%. I no longer will buy a shimano product if weight matters, they just flat out lie.

Still a great stem and very stiff. I've switched all of my road and most of my CX bikes over to their Vibe round bars, in either the carbon or alu. They are a bit over advertised weight, but feel great. Their carbon bars are the only ones I've found to be stiff enough to my liking.
Just like Deda used to do and weigh only the stem, no hardware at all, meaning no bolts and no faceplate. I bet that is the case throughout the range. Once they get a bad rep for it they will change it. I am pretty sure Deda is more actual (meaning usable stem) weight.
