Improving on the original S-Works Aerofly the S-Works Aerofly 2 takes the knowledge of countless Win Tunnel hours & 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 youll find a textured surface that ensures your hands stay in place in when its wet plus theres a step that makes bar tape even with the tops of the bars for both comfort & a clean look.
