This pair of rim brake Zipp NSW tubeless ready wheels have been used for photo and marketing purposes. Unboxed and handled, but in near perfect condition and carry full manufacturer's warranty. All parts, bags and owners manual included.

The 45mm deep 303 NSW Carbon Clincher Rear Wheel was developed to be raced, but it is strong and resilient, with a smooth ride that makes this a great every day wheel. Training and racing on the same wheels equals incredible confidence and familiarity. Clincher and Tubeless tire options make tire management simpler and more cost effective than tubulars. With it's lower profile, incredible stability and 825 gram weight, the 303 NSW can adeptly handle corners at high speed, and spins up immediately as you power out and onward. Complementing the 19mm internal width is a brake track width of 26.4mm, and max width of 26.5mm, so riding tires from 23-28mm wide means you can maximize the tire/wheel aerodynamic relationship carried through the ABLC Sawtooth™ rim dimple patterning. This advanced NSW dimple design consists of 12 nodes that are precisely clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth induces small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability while providing aerodynamic speed.

The hubset is Zipp&s #39; Cognition series and while the real magic happens in the rear hub, the front hub was developed with a unique scalloped edge hubshell design that optimizes the stiffness of the lightweight alloy hub design to preserve the effective bearing bore diameter under load. In order to keep the Swiss steel bearings precisely in line with each other and the oversized alloy axle - for the lowest friction and resistance possible, the scalloped edges and even, high radial spoke tension, ensure the hub shape won't distort. This is type of detail that wins races and establishes record times. Every watt of energy conserved or gained through design saves valuable seconds.

Rim braking with carbon wheels is a huge consideration for all cyclists, and Zipp's outstanding Showstopper™ brake track offers unparalleled braking and heat management through pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin in a molded groove pattern. That pattern has been matched with the surface and cooling channels of the included Tangente Platinum Pro Evo brake pads for incredible stopping power in dry or soaking wet conditions, in any terrain. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two channels have maximum interference as the grooves create greater braking force without heat build-up. And just to raise the bar a little higher, Zipp uses ImPress™ technology to apply graphics directly to the rim surface, giving the wheels an even stealthier appearance without mitigating the aerodynamics of the dimple structures.
