The 303 NSW Tubeless Clincher wheel is Zipp's ultimate allrounder for racing cyclists. The strengths of the 303 NSW lie especially on undulating terrain and changing wind conditions.
To optimize the aerodynamic performance, the Zipp engineers rely on the striking ABLC Sawtooth structure. The design is aerodynamically optimized for use with real 25 mm wide tyres and combines low air resistance with high driving stability. In addition, the 303 NSW rim scores with tubeless compatibility and strong braking performance.
The imprint graphics not only provide valuable weight savings, but also enable a unique and durable application of the four letters most feared by the competition in cycling racing: Z-I-P-P.
The revised ABLC (Aerodynamic Boundary Layer Control) design reduces drag through more and less turbulence to ensure unsurpassed stability and control even in the strongest winds.
Showstopper technology uses a molded silicone carbide (SiC) surface brake ring for maximum wet braking performance. The result is a braking performance that is equal to that of an aluminium rim, even in torrential rain. Showstopper technology offers greater wet braking power than any other carbon wheel.
Zipp Cogniton Hubs
The new Cognition Straightpull hubs, made of high-strength Z310.9 aluminum, are extremely lightweight. The Swiss stainless steel bearings are the most precise in the industry. Specially designed hub bodies distribute the load of the spokes more evenly over a larger area to prevent torsion in the bearing area. The result is lower resistance and greater durability. The 9 mm hub axles are extremely stiff. The hub itself is milled using modern EDM technology so that 50 percent harder materials can be machined 20 times more precisely. The Cogniton hub series with the Straightpull spoke holder offers an even higher lateral stiffness.
