Subtle looks, damping, light weight, shape, width
Expensive, I guess, but relative to other carbon bars, they're not so bad.
Love these bars - they're light, the graphics are subtle and not in our face, the shape, width, sweep, everything is just "right". Had them on the DH bike first, liked them so much I got the same setup for my trail bike. One unexpected benefit was the damping - I don't notice any flex in use, but on a holiday after four days uplift riding over rocky terrain, my hands weren't tired/cramped and I had no arm pump. Worth the money for that alone.
