Ride away. Explore boundaries. Do so with speed, stability, and control. That’s the 303 NSW Carbon Clincher Tubeless Disc Wheel. Zipp’s 45mm rim depth proved ideal as a do-it-all wheels for cobbles, pavement, cyclocross, and gravel. Now add to that tubeless compatibility and options to run wider tires.

Without the constraints of rim brake caliper compatibility or brake-track requirements, their engineers were free to modify the NSW rim design to be disc-brake specific as well as to be more aerodynamically efficient and stable at the most common wind angles. For starters, the ABLC Sawtooth dimple design extends all the way to the rim’s edge. The result is greater AeroBalance, their name for optimised aerodynamic efficiency and crosswind stability. 

The 303 NSW Tubeless Disc-brake is optimised for wide tires to meet the performance needs of modern riders in search of low rolling resistance and high comfort. Additionally, their engineers carefully considered the rim-to-tire interface and how specific tire and rim widths affect aerodynamic performance. With an internal width of 21mm, the wheelset test fastest with a 28mm tire in the majority of wind angles.

Designed to be tubeless compatible, the 303 NSW Tubeless Disc brake wheels feature a rim bed made with internal ridges to lock the tire’s bead in place. A tubeless setup allows you to run lower tire pressure for more comfort while reducing the risk of pinch flats.

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 Disc-brake hubset’s Axial Clutch technology, we’ve 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 their 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.

All NSW rims are handmade in Indianapolis, where Zipp's engineering, manufacturing, and testing are conducted and includes "The Nest" advanced development lab where NSW was born. 


Features

ImPress - They’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 NSW a distinctive stealthy look.

ABLC SawTooth Technology  (Aerodynamic Boundary Layer Control) - Their 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.
