  • Light enough to fly up climbs, tough enough to excel in the cobbled classics, and with the industry’s best available braking performance for the most technical descents, the 45mm deep 303 NSW is built for a singular purpose: To be fast, everywhere. But the 303 NSW is no ‘race day only’ wheelset to be tucked away in a wheel bag until a race number is pinned to the rider’s jersey. It’s built to take the abuse of everyday training rides. Zipp has achieved this reliability at a lighter weight with a revised carbon fiber layup developed through testing on the famed cobbles of the Arenberg Forest with the world’s fastest riders.

NSW Technologies:

  • COGNITION HUBSET - The Cognition hubset with Axial Clutch Technology reduces drag by disengaging the ratchet mechanism when coasting. So you can approach corners at higher speeds, and ultimately, save time. A star-flanged straight-pull hubshell design on the rear hub distributes the load placed on the hub flange away from the bearings. Zipp have also developed a unique scalloped edge hubshell design for our front hub. This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied. That means you get bearings that quietly stay in place, roll faster, last longer, and provide a laterally stiffer hub.
  • ImPress -  Zipp have employed their own ImPress graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were design to do – help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give 808 NSW a distinctive stealthy look. 
  • ABLC SawTooth - The new Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing 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.
  • Showstopper - The industry leading silicon carbide Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.
  • Each Wheel Includes - Zipp black titanium skewer, Zipp valve extender by Silca, Zipp individual wheel bag, Zipp Platinum Pro Evo brake pads, Zipp tube 700c x 19-25mm, Zipp rim tape 700c x 20mm.
