Zipp Super-9 Disc Carbon Rear Track Wheel (Tubular)

Zipp’s Super-9 Disc Carbon Track Wheel underwent extensive fluid dynamic modeling, wind-tunnel testing, and relentless refinement so you can enjoy no-holds-barred aero domination. With a variance in width of just a single centimeter from rim to hub, the Super-9 is almost invisible to the wind. Plus the wide rim creates a virtually seamless integration with the tire, optimizing aerodynamics and allowing wider tires and less rolling resistance.
