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), but that also have a myriad of features that make them comfortable. Starting with the tops, 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. Next up, Specialized took feedback from their World Tour teams and pushed the airfoil forward, and this ensures more forearm and knee clearance. And finally, they made the Aerofly II lighter. In fact, at a mere 235 grams in size 42cm, it’s the lightest aero road bar in its category. Consider it aero without compromise.
