Not all aero carbon bars can be shown to make real improvement in reducing drag over a round bar design. There are many variables in testing. Luckily for Specialized they perfected the process in developing the the Venge then the Tarmac SL7, in their own wind tunnel as well. They could work with fixed, reliable data with the same equipment in the same facility. Improving on the original S-Works Aerofly, the S-Works Aerofly II takes the knowledge of countless Win Tunnel hours and transfers it into handlebars that are not only fast (you save around 20+ seconds over 40k versus a round bar), but that also have a myriad of features that make them comfortable and offer better overall confidence and performance.

Starting with the tops (which are designed to be used bare- without tape), you'll find a textured surface that ensures your hands stay in place in when it's wet, plus there's a step that makes bar tape even with the tops of the bars for both comfort and a clean look. The Specialized design team took feedback from their World Tour sponsored teams and pushed the airfoil forward on an angle, which ensures more forearm and knee clearance without sacrificing anything else. The engineered FACT carbon construction made the Aerofly II lighter than the original as well, at a mere 235 grams.

In size 42cm, it’s the lightest aero road bar in its category. Consider it aero without compromise especially now that all mechanical or electronic wiring, etc., is now internal, and manageable to set-up. Specialized hits all the key details with textured clamping zones, lever mount graphics for an accurate installation, and reach and drop numbers that favor a road race build- just a little more generous than a true compact in all sizes except the 38cm.
