The Zipp 303 NSW Carbon Clincher Tubeless Disc Wheelset's proven 45mm rim depth is ideal as a do-it-all wheelsest for cobbles, pavement, cyclocross, and gravel. Without the constraints of rim brake caliper compatibility or brake-track requirements, Zipp 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, Zipp's name for optimized aerodynamic efficiency and crosswind stability. The 303 NSW Tubeless Disc-brake is optimized for wide tires to meet the performance needs of modern riders in search of low rolling resistance and high comfort. Additionally, Zipp 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, Zipp reduced this drag by disengaging the ratchet mechanism when coasting. Zipp testing shows that the best traditional three-pawl hub designs have twice the rotating friction as the 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. The wheelset features 24 Sapim CX Ray spokes front and rear, and each wheel includes Zipp Tubeless valve extender and valve-core wrench, Zipp rim tape (factory taped), Zipp Tangente quick-release skewer, Zipp thru-axle end caps, and Zipp individual wheel bag.
