Zipp SL-70 Aero Handlebar Black 44cm

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 VukaSprint.

The bar’s distinctive wing-shaped top is designed using Computational Fluid Dynamics (CFD), the same software used to design Zipp® wheels. Our research showed that a traditional round-tube section creates drag of about 0.74 Newtons, which we found 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 a 70mm reach to allow proper fit without compromising stem length and steering control.

The 10-degree ramp angle to the brake hoods eliminates the need for up-rotated bars. The bar also provides ample wrist clearance for riding and sprinting in the drops.

• UCI legal.
