The SL-70 Aero is a UD carbon handlebar packed with innovations for the best ergonomics, aerodynamic performance and fit in its class. With a wing-shaped handlebar top designed using Computational Fluid Dynamics (CFD), the SL-70 Aero features Zipp's latest handlebar improvements while building on VukaSprint's aerodynamic heritage. The difference this design makes is real, saving 6.4 Watts over a round tube handlebar. In addition to aerodynamic performance, the SL-70 Aero features a 70mm reach to allow for a proper fit. It also provides plenty of wrist space for driving and sprinting on drops. With Rapid Routeā¢ technology, internal cable routing is made easy.
