About Zipp 202 NSW Carbon Clincher - Front Wheel

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.

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 reduced this drag by disengaging the ratchet mechanism when coasting. Their testing 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. 

With less internal hub drag a rider can pedal less when riding through rolling hills or drafting in a headwind. Or 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 Zipp use magnets, rather than steel springs, to move and engage their light weight Metal injection Molded (MIM) ratchet rings for unrivaled reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn’t a more secure freehub mechanism on the market.

Zipp's Axial Clutch freehub mechanism is also compatible with XDR drivers. This gives riders the option to select a 10-42 cassette to assemble a 1x11 drivetrain with an equivalent range to either a compact or standard road double drivetrain.

A star-flanged straight-pull hubshell design on the rear hub distributes the load placed on the hub angle away from the bearings. Zipp 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. 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's chosen Swiss stainless steel bearings specially made to their specs to provide the longest lasting, lowest friction performance available.

Technologies

Showstopper - is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin.

ImPress - Zipp 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 NSW a distinctive stealthy look. 

ABLC SawTooth Technology  (Aerodynamic Boundary Layer Control) - Zipp's 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.
