Advanced Acceleration
When Zipp gave its top engineers in The Nest advanced development lab the task of shedding more weight from its lightest carbon clincher wheelset, the 202 Firecrest, while also improving rolling friction, aerodynamics, and braking, it was a very tall order, when Zipp asked them to do all of this without sacrificing durability, it looked like an impossibility, but the NSW advanced development team delivered on every request and built the ultimate climbing wheelset, a climbing wheelset strong enough to use on every ride.

Engineered to be the fastest accelerating carbon clincher Zipp has ever made, 202 NSW flies up the toughest climbs, and then shaves even more time off of the descents to follow. And because extracting greater speed on the mountain is only half the battle, Zipp built 202 NSW to deliver the lowest aerodynamic drag available for a rim of this depth for speed everywhere else.

In order for a climbing wheelset to be world beating it has to do more than simply deliver low weight; it has to deliver uncompromising performance on every level. This is why Zipp engineers in The Nest chose to enhance the world’s fastest climbing carbon clincher, the 202 Firecrest.
With a new lighter carbon fiber layup for the 32mm deep 202 NSW they’ve dropped weight where it matters most, at the outer edge of the wheel, while maintaining the durability and lateral stiffness that Firecrest is famous for. Then they reduced aerodynamic drag with ABLC Sawtooth™ technology and used ImPress™ graphics to ensure that nothing stood between the air flowing over the rim and the dimples made to smooth that flow. Knowing that there is no benefit to a wheelset that climbs fast and descends slow, NSW engineers incorporated our Showstopper™ brake track for the most confidence inspiring rim braking performance available, whether the road is wet

Engineered for speed when approaching, ascending, traversing, and descending the world’s toughest mountain roads, Zipp 202 NSW is a wheelset that can only come from one place, The Nest, where the world’s fastest wheels are made.

Weight (manufacturer): 615 g (front), 760 g (rear).

Technical Specifications

Technologies
NSW - Nest Speed Weaponry
The Zipp NSW Series is a science, a philosophy and a mission to engineer the fastest, most stable and highest performance cycling components ever realized.
Within the NSW Series, Zipp will develop and refine halo-level products with the most advanced technologies on an ongoing basis. The focus is on transforming innovative ideas into tangible gains in speed. NSW – for Nest Speed Weaponry – comes from the nickname “The Nest” Zipp engineers gave to the windowless, high-security advanced-development lab in the corner of the Zipp factory. It’s where only the best fledgling ideas fly.

Cognition™ Hubset
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 the Cognition hubset's Axial Clutch™ technology, Zipp has reduced this drag by disengaging the ratchet mechanism when coasting. Tests shows that the best traditional three-pawl hub designs have twice the rotating friction as Zipp's Axial Clutch equipped Cognition rear hub, and the most popular hubsets using a similar drive mechanism as Axial Clutch were found to produce four times the rotating friction.

Inside the Axial Clutch mechanism Zipp uses magnets, rather than steel springs, to move and engage the light weight Metal injection Molded (MIM) ratchet rings for the most reliable and consistent operation possible. With 36 points of engagement that all interlock simultaneously, there isn't a more secure freehub mechanism on the market.

A star-flanged straight-pull hubshell design on the rear hub distributes the load placed on the hub angle away from the bearings. Zipp has also developed a unique scalloped edge hubshell design for the front hub. This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied. Both of these hubshell design elements ensure that bearings quietly stay in place, roll faster, last longer, and provide a laterally stiffer hub. About those bearings, Zipp has chosen Swiss stainless steel bearings specially made to its specs to provide the longest lasting, lowest friction performance available.

Impress™
Zipp's ImPress™ graphics 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 404 and 808 NSW, ImPress graphics give the 303 NSW a distinctive stealthy look while keeping the rims as light as possible.

ABLC Sawtooth™ Technology
The new Sawtooth dimple design consists of 12 nodes that are precisely clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 32 km/h. 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 imparts peace of mind in gusty wind conditions 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 NSW. Zipp wanted braking performance that was better than aluminum rims and any other carbon rim, and they've achieved that goal. Zipp's industry leading silicon carbide Showstopper™ brake track delivers unmatched 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.

Born Of Science. Realized By Hand.
Zipp NSW was developed using CFD (Computational Fluid Dynamics) post-processing software and months in the wind tunnel, including the Aerodynamic Bike Testing Facility at the ARC Wind Tunnel, a short drive from Zipp’s Indianapolis facility. The advanced development engineers at The Nest took that data and created the rim shapes that became the NSW.
Zipp do this because, as one of our advanced development engineers, Dave Morse, is fond of saying, “The wind tunnel will never be replaced as the gut check for wheel design.”

All Zipp NSW rims are laid up, molded, drilled, and built in Indianapolis by Zipp technicians, where expert wheel builders hand lace the rims to the European-made Cognition hubset using Belgian Sapim CX-Ray spokes and Secure-Lock nipples to ensure precision alignment and even spoke tension. The end result is a handcrafted wheelset that stays fast and true for years to come.
