It weighs \u003cstrong\u003e1050g\u003c\/strong\u003e, which Zipp lists among the lightest disc wheels available. The shape runs wide and parallel from the Sram-XDR hub, then curves inward where it meets the hookless tire bed. The goal is a rear wheel that rolls efficiently on real-world pavement as well as being aero.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe design follows Zipp's \u003cstrong\u003eTotal System Efficiency (TSE)\u003c\/strong\u003e approach. Wind resistance, gravity, rolling resistance and vibration losses are treated together, not aerodynamics alone. In practice, the Super-9 is designed for a wider tire at moderate pressure, not a narrow tire pumped hard. Zipp says this gives better handling and cornering, and a disc that is \u003cstrong\u003estiffer and more durable than the previous Super-9\u003c\/strong\u003e. A \u003cstrong\u003eTyreWiz 2.0 pressure sensor is built in\u003c\/strong\u003e, so you can confirm your pressure before the start.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cp\u003eTriathletes and time trialists on \u003cstrong\u003edisc-brake TT or tri bikes\u003c\/strong\u003e who want a full-disc rear wheel for racing\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRiders already running, or moving to, \u003cstrong\u003ewider tubeless tires at lower pressures\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAthletes who want to save energy on the bike for the run\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRiders pairing it with a \u003cstrong\u003ecurrent Zipp tubeless front wheel\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConsider a different wheel\u003c\/strong\u003e if your frame can't fit a 28mm rear tire, if you run rim brakes, or if your total system weight is over \u003cstrong\u003e115kg \/ 253lbs\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 dir=\"ltr\"\u003e\u003cstrong\u003eWhat to Look For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eFrame clearance and tire choice:\u003c\/strong\u003e 28mm is both the minimum and the recommended tire size.
