Equip yourself with the wheel that has won World Championships and reach the pinnacle of your own potential. Zipp’s Super-9 Carbon Disc underwent extensive fluid dynamic modeling, wind-tunnel testing and relentless refinement so that you enjoy no-holds-barred aero domination. At the road, the sides of the rim slant in towards the tire for a virtually seamless integration between the tire and rim. And, with a variance in width of just a single centimeter from the rim to the hub plus Zipp’s renowned dimpled carbon on the sides, the Super-9 is almost invisible to the wind. You'll also love Zipp's fine 188 hub, the amazing weight of only 995 grams and that this wing of a wheel comes with the right brake pads, valve extender and even a lightweight quick release.
