The S Works Carbon Aerofly Road Handlebars from Specialized was developed in their wind tunnel. This bar saves 17 seconds over a 40km distance against a traditional shallow bend road bar. This time saving comes from the distinct aero shape, reduced tape on the tops, and full internal cable routing. The bar uses a FACT carbon construction which gives a light weight, stiff, and aerodynamic design. The internal routing means it is optimized for internal brake and gear cable routing giving a cleaner look as well as protecting your cables. The clamp diameter is 31.8mm for oversized bars and come in a unidirectional gloss carbon black finish in either 40, 42 or 44cm widths.
