I'm selling a Bontrager XXX VR-C carbon road handlebar - 44cm.  It came on my new Emonda and after one ride I figured out that it's just too wide for me so I bought a 42.  It's a ridiculously light 190 grams.  

Pulling it off the bike I scraped the curved part of the right bar a bit pulling the brake levers off, but they will be under the tape anyways so it doesn't matter.  You can see it in the pix.  Pretty normal for taking a bar off.  Everything that will be showing is fine.

They retail for $349.  You can find all the info on them on the Trek site, but the highlights are below.  

They are a true 44cm center to center on your brake hoods.  124drop, 100mm reach.

Overview From Trek:

XXX is a testament to the power of judicious carbon composite engineering. 

Not only is it incredibly light and stiff, but its OCLV Carbon construction also offers an unparalleled ride quality. 

The Unique Variable Radius Compact bend creates the ideal hand position for quick transitions from the tops to the drops.

Key Features:

OCLV Carbon fiber construction

Variable Radius Compact (VR-C) design allows shorter reach and drop

Laser-etched brake lever position lines for spot-on control setup
