Zipp Launches New 808 NSW Carbon Clincher Wheelset

Designed with the time trialist and triathlete in mind, Zipp launched its inaugural 808 NSW carbon clincher wheelset this week, as part of its new  NSW Series.

The new 808 feature a new rim shape for improved aerodynamic efficiency and reduced side force, as well as a new hubset for increased durability and less drag. 

According to Zipp, the new wheelset represents the brand’s most advanced technology, as it relates to tangible gains in aerodynamic efficiency and stability. Moreover, Zipp says, the 808 provides a 3-4 watt savings compared with its benchmark wheelset, the 808 Firecrest, which means an estimated 90 seconds at 40km per hour over 112 mile (180.25km) Ironman® -distance.

The 808 was developed using more than 40 concept studies using CFD (Computational Fluid Dynamics) post-processing software and multiple wind-tunnel trips, including the Aerodynamic Bike Testing Facility at the ARC Wind Tunnel, a short drive from Zipp’s Indianapolis facility.

As a testament to the new wheelset’s effectiveness, the 808 was ridden to 1-2 finishes at the World Championships in Richmond, Virginia last month – with Velocio-SRAM Pro Cycling capturing gold in the Elite Women’s Team Time Trial and Boels-Dolmans Cycling Team winning the silver. And, in triathlon world, Jan Frodeno of Germany won 70.3® World Championships in Austria, while fellow German Sebastian Kienle was second. 


NSW Technologies:

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. 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.

ABLC™ SawTooth™
Our 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.

Our 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.
