The new SL-70 Aero 31.8mm Carbon Handlebar from Zipp are, in every way, a high-performance bar. Crafted from unidirectional carbon, this bar is packed with the innovations for best-in-class fit, ergonomics and aerodynamic performance. It features a wing-shaped bar top, Zipp’s latest bar refinements, while building on the trend-setting aero legacy of the VukaSprint.
The bar features a distinctive wing-shaped top which has been designed using Computational Fluid Dynamics (CFD), the same software used to design Zipp Firecrest wheels. They found out that a traditional round-tube section creates drag of about 0.74 Newton’s, which requires 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. Beyond aero performance, the SL-70 Aero features the a 70mm reach to allow proper fit without compromising stem length and steering control. The revised 10-degree ramp angle to the brake hoods eliminated need for up-rotated bars. The bar also provides ample wrist clearance for riding and sprinting in drops. Available in Black in 38, 40, 42 or 44cm
