Zipp’s 808 NSW Tubeless Disc-brake wheelset features a rim shape that aerodynamically integrates wider tubeless tires for high-performance road cycling at our deepest rim depth, 82mm. The benefits of tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with high cornering grip and low rolling resistance. Also, you get the wider tire options and increased stopping power of disc brakes. The 808 NSW Tubeless Disc brake wheelset is optimized for smoother pavement and are aerodynamically optimized for 25mm tires. By extending our patented ABLC™ Sawtooth™ dimples all the way to the rim’s edge on each of the wheels, NSW disc brake rims deliver higher frequency wind vortex shedding for best-in-class crosswind stability. This wheelset allows you to run tubeless or traditional clinchers. Zipp’s new wheel cosmetics make this wheelset a perfect pairing of speed and style.

Zipp’s 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.
With the Cognition hubset’s Axial Clutch technology, we’ve reduced this 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. We’ve 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.
We’ve employed Zipp’s 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.
With Cognition’s Axial Clutch technology, we’ve reduced this drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedaling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don’t require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism we use magnets, rather than steel springs, to move and engage our light weight Metal Injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn’t a more secure freehub mechanism on the market.
The XDR driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer.
