The Shotrt - Range Rocket . Zipp’s new Super-9 disc excels in races won on full-throttle power. Intended for time trials, track racing, and the occasional Tour de France prologue, the Super-9 is 40% stiffer than our 900 disc and matches the Sub-9’s remarkable ability to generate forward lift when paired with Zipp Tangente tire. Slots cleanly into the tightest of chainstays, the Super-9 tapers in width from 27.5mm at the hub to 23mm at the perimeter. With a slightly wider tire bed than our other discs, the Super-9 exhibits superb aerodynamics with tire widths from 21-23mm. The Super-9’s hub features the same 17mm axles as the 188 road hub, along with adjustable bearing preload with the industry’s only aero preload nut. The standard version of the Super-9 weighs less than 1,000 grams and is convertible between road and track setups.
