The Super 9 Carbon Tubular Disc Wheel is lightweight, stiff, and marks Zipp's fastest wheel to date. The wheel features a similar perimeter shape as the super fast Sub 9, but Zipp streamlines the Super 9 by making it flat from its widest point all the way to the hub. Not only does this make the Super 9 fast, but it's also stiffer than previous iterations. To eliminate drag, the Super 9 feature Zipp's Aerodynamic Boundary Layer Control ABLC, which is a dimpling pattern that manages and smooths airflow across the surface. The Super 9 is equipped with a hub manufactured with high voltage EDM technology, which allows Zipp to machine 50% harder materials. The Super 9 is available with Campagnolo and ShimanoSRAM 11 speed compatible freehubs, and it is also convertible to a track setup.
