Aero advantage of the super-slim tops is probably pretty negligible but these bars look amazing and feel great under the hand. There's no question cranking behind that swept profile gives you wings. Very nice broad flat area from the tops toward the shifters gives lots of grip options. The feel is solid and connected on the road, with a nice clear read on what the surface is doing without being buzzy (or too flexy). I previously used a few generations of 3T's Ergonova Pro bars and have my fit dialed around them so I appreciate the Ritchey Streem's similar reach/drop dimensions. The Streem's more classic curve drop actually brings the levers closer to my hands, if a somewhat different range of hand positions. A warning: the underside cable-routing tunnels are excellent to work with, but their tolerances are very tight and will /not/ fit braided carbon-look Jagwire LEX-SL housings given they're a bit thicker than the solid-color stock. Had to go back to standard black housings and hoses due to this.

Upgrading my handlebars at this point just made sense and I will admit my bars had been an afterthought in terms of importance, in my mind they functioned, but now it is time to take it to the next level and replace my old bars; Ritchie Comp Aluminum. I considered several other handlebars, in fact I read nearly all of the "descriptions" of handlebars offered here at CC. I ultimately chose the Ritchey WCS Carbon Streem II These bars feel fantastic!! They are super comfortable whether in the drops, hands on the hoods or gripping the flat portion. I love the flat design and I would argue that they do offer an aero advantage, one thing is for certain you will not be disappointed with these bars. Wondering how the Streem II performs with road noise and vibration? the answer. beautifully!! I PURPOSELY took a ride over cobblestone to test the feel, I did not get jumbled around and beat up, later on the road when rolling over rough patches I expected to be jolted around and to my delight I was not, these bars do a great job absorbing energy. Another important question is whether or not these bars are stiff, and again the answer, YES. Whilst riding a local bike trail I approached a set of "rollers" I got out of the saddle and attacked them from the drops, I am by no means a world class sprinter but I am a big guy at over 95kg, and not even the slightest flex. After a couple 40 mile rides and 50 mile rides not the least bit uncomfortable. Definitely an upgrade to my bike aesthetically and definitely next level performance.
