Description of ZIPP 808 NSW Carbon Clincher Front Wheel - QR - Black

As the inaugural wheels in the NSW Series, the Zipp 808 NSW carbon wheels offer a groundbreaking rim shape with greater aerodynamic efficiency and reduced side force as well as the new Cognition hubset for increased durability and less drag. The 808 NSW wheels with a rim depth of 82 mm are designed for triathletes, time trialists or any cyclist looking for increased speed and stability.


The 808 NSW carbon front wheel leverages Zipp’s advanced technologies for tangible gains in aerodynamic efficiency and stability. The 808 NSW provides a 3 to 4 watt savings compared with the benchmark, the 808 Firecrest, which means an estimated 90 seconds at 40 km/h over 112 miles (180.25 km) Ironman® distance.

Zipp 808 NSW was developed wth the help of 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 in Indianapolis near Zipp’s facility.

Zipp 808 NSW technology was ridden to first and second place finishes in two world championship events just as it was being introduced in 2015. In triathlon, Jan Frodeno of Germany won 70.3® World Championships in Austria while fellow German Sebastian Kienle was second. In cycling, Velocio-SRAM Pro Cycling captured gold at the Elite Women’s Team Time Trial and Boels-Dolmans Cycling Team the silver at the UCI Road World Championships in Richmond, Virginia. This successes were crowned again in 2015 by Frodeno when he secured the victory at the Ironman® final in Kona, Hawaii.

Cognition hub

Every time a conventional hubset starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. 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 magnets are used rather than steel springs to move and engage Zipp's light weight Metal Injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, Cognition hubs offer one of the most secure freehub mechanisms on the market.

ImPress™

Zipp’s ImPress™ technology prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do – control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. Like the 808 NSW, ImPress graphics also give the NSW wheels a distinctive stealthy look while keeping the rim as light as possible.

ABLC (Aerodynamic Boundary Layer Control) Sawtooth™

The new Sawtooth™ dimple design consists of 12 nodes that are precisely clocked to start aerodynamic shearing at a rate of 50 Hz at a rider speed of 20 mph. 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. That crosswind stability then imparts peace of mind when the weather turns south while saving watts that would have been expended while attempting to hold your line.

Showstopper™

When it comes to braking, "good for a carbon rim" wasn’t good enough for the NSW wheels. Zipp wanted braking performance that was better than at aluminum rims, and they achieved that goal. The silicon carbide Showstopper™ brake track, which is counted among the industry leading, delivers an extraordinary stopping power and modulation regardless of weather conditions or the length of the descent. With Showstopper™ braking performance, you’ll need to find another excuse not to ride on rainy days.
