Offering you guaranteed speed, stability in crosswinds and efficient rim brake control in all weathers, the Zipp 808 NSW Carbon TL Wheelset is the ideal upgrade for your road or time trial racing bike. They're also tubeless-ready.
Zipp’s 808 NSW Tubeless rim-brake wheelset features a rim shape that aerodynamically integrates wider tubeless tyres for a new era of high-performance road cycling at Zipp's deepest rim depth, 82mm.
The 808 NSW Tubeless allows you to run tubeless or traditional clincher tyres. The benefits of tubeless include superior flat protection, the ability to run lower pressures for a smoother ride with high cornering grip and low rolling resistance. The 808 NSW Tubeless’ 19mm internal rim width and corresponding outer rim shape are optimised for aerodynamic optimisation with 25mm tyres. Zipp’s updated wheel cosmetics make this wheelset a perfect pairing of speed and style.
Lifetime Warranty
Zipp wheels, handlebars, stems and seatposts come with a lifetime warranty for product issues while riding. The lifetime warranty is not transferrable. Proof of purchase is required.
Technologies:
Impress
Zipp has employed its ImPress graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were designed 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.
Axial Clutch
With Cognition’s Axial Clutch technology, riders can maintain speed through corners that don’t require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism, Zipp uses magnets, rather than steel springs, to move and engage its lightweight 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.
Cognition Hubset
With the Cognition hubset’s Axial Clutch technology, Zipp has 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. Zipp has also developed a unique scalloped edge hubshell design for its 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.
ABLCSawtooth
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.
Aerobalance
Zipp’s sole mission is to help you go faster. That's why its wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing and the RollingRoad ride simulator – to refine aero performance to new levels of excellence. Over the decades of innovation, Zipp's engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimising the effects of crosswinds on handling. This optimising of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.
Showstopper
Zipp's 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.
