been thinking about changing the bars over to CF on the Domane, but what holds that up are all the other tasks involved to do it. Just cannot justify the change when everything is wrapped & positioned where I want it all now.
If you're in the market for some handle bars, I'd go CF. My other cycle has CF & I will miss riding it just for that feature.

Just checked and a set of Zipp alloy bars and carbon in the same series were within 20g of each other - 240-260g range. Roughly 0.04 lb difference. This used to be true with alloy being the lighter now it seems to be the opposite. Regardless at 20g it's negligible. Cost. shape and durability are really the only differences. Again I do understand that integrated bars/stems drop the weight by a lot.

Basically all bars are heavier than they used to be able to be. A Zipp SL carbon bar in 2006 was about 165g.

So I am looking at upgrading my current Oval Alum handle bars to something more aero. Almost everything on my Fuji has been upgraded. I am looking at the Easton SL70 Aero Carbon or The Zipp SR70 Aero Carbon, but I also found The Bontrager Aero VR-CF Road Bar, the later looks promising just a little heavier than the first two choices but also 1/3 the price because they are not carbon. Leaning to the Bontrager because it has room to mount my Quad Lock mount. Thoughts? Are Carbon bars worth the money?

It's funny because i remember the opposite. All carbon bars were heavier than comparable alloy bars. Maybe back in '06 that wasn't the case but I feel like from '10 on it definitely was the case. I sat there so many times wondering why anyone would ever buy carbon for bars. Now it seems like they are the same to slightly lighter so meh. Still not something I am running out to put on a bike that has a high potential of hitting the deck.

The case for carbon fiber bars is stronger than the case for carbon fiber frames.

From my point of view carbon frames are markedly lighter than Alloy frames.
They are way more repairable than alloy frames
Pricing - they really aren't much more expensive at the lower end at all and we can always argue the higher end is expensive because of marketing and price pointing.

That said, there are also quite a few CF "aerodynamic" handlebars which are > 200 g, some almost 250 g, which gets very close to a lightweight alloy bar.

Just for kicks another datapoint. A 2005 Easton EA70 handlebar was 225g; today Comp Cyclist shows the weight for same nominal model at 280g.

Despite it being rather strange to refer to steel as being an alloy frame I will say that carbon can out perform steel (alloy) or aluminium (alloy) in every respect if it is designed to do so.

Steel is great. Always has been but it truly is just left for a tiny market segment on the high end or for the throngs of Bicycle Shaped Objects (BSOs) on the lowest end. It's a bit like saying, "You think traveling by airplane is neat then I'm going to blow your mind with going by sailboat."
Because of where it dropped to steel seems to be harder to find, more expensive than carbon if we are talking something nice, and less repairable (only from the standpoint of finding someone with the skill, knowledge and time to repair it correctly) than carbon.
As for ride comfort - that's subjective. I am more comfortable on a bone shaker stiff as possible crit bike with steep angles than I am on a lay-z-boy cruiser with soft steel. I totally understand how for some they want the most muted feel possible. It's why those old Cadillacs drove like boats. Sail boats you might even say.

Bronze is an alloy of copper, tin and zinc.
An alloy is defined as a mixture of metallic (and sometimes other) elements. It is not unique to aluminum, so "alloy" is not a synonym for aluminum, nor is "alu" or "alum", the latter of which is a sulphate salt of aluminum.
Aluminum (or aluminium) has a very simple and convenient IUPAC abbreviation that appears on the periodic table: Al
There is no need to invent non-standard terminology or abbreviations, and then get annoyed when someone doesn't adhere to it.
(For the record, I was suggesting that one advantage of carbon vs. aluminum alloy handlebars is that in many cases they are more comfortable, despite being more stiff, even if there isn't a significant weight advantage. Carbon frames, on the other hand, do tend to be more fragile than metallic frames, and in my very subjective opinion, more comfortable than aluminum alloy, and typically less comfortable than iron alloy. Those who don't like a bit of flex generally prefer stiffer carbon frames, but now some of those carbon frames, like Trek's Supercaliber and Domane, have flex properties engineered into them by design. Perhaps they are starting to mimic the inherent properties of steel that some people covet.)

Normally, I refer to them as steel, aluminum and carbon.
Alum isn't a great frame or handlebar material, but it might be helpful to staunch the bleeding of your wounded ego.

Thank you for those definitions, Captain Pedantic. In cycling, it is widely accepted that "alloy" refers to aluminum alloy frames, "steel" refers to steel alloy frames, and "titanium" refers to titanium alloy frames. Your crusade to refer to them all as alloy frames is pointless.

Calling carbon fiber plastic is factually inaccurate.
Calling aluminum alum is factually inaccurate.
Stating that steel is not an alloy is factually inaccurate.
So the analogy applies, but opposite to the way that you presumably intended.
Oh, there should be a space in "carbonfiber", and one ought not to start a sentence with "And".

But there is one crucial difference:

Then of course there is the "scandium" bike frame material, which, as it turns out, is yet just another type of aluminum alloy, and a small amount of Sc is indeed included (pun intended). Scandium sounds exclusive and expensive and has snob appeal, while aluminum sounds cheap, (which is probably why people call it "alum" or "alloy"). So put a trace amount of Sc in there, and raise the price. By similar logic, that iron alloy could be sold as a carbon frame, with a Fe matrix to add fiber-like strength, but as a regular three-dimensional array for added durability.
