Zipp SL-70 Aero Road Handlebar – Black/White
Zipp's SL-70 Aero is, in every way, a high-performance bar. This unidirectional carbon handlebar is packed with innovations for best-in-class fit, ergonomics and aerodynamic performance. With its wing-shaped bar top, the SL-70 Aero features Zipp's most advanced bar refinements while building on the trend-setting aero legacy of the Vuka Sprint. The bar's distinctive wing-shaped top is designed using Computational Fluid Dynamics (CFD), the same software used to design Zipp® wheels. In-house research showed that a traditional round-tube section creates drag of about 0. 74 Newtons, which Zipp found required about 7. 5 watts of effort at 30mph (48. 3kph) to overcome. The airfoil developed in CFD that is used in the SL-70 Aero handlebar creates just 0. 11N of drag, which means a savings of 6. 4 watts over a round-tube section.
