My oh my.
Zipp's Nest Research and Development Department took in their golden 303 wheelset and turned out one that was pure magic. Using a revised carbon layup that was dialed-in by pro riders hammering over the famous cobbles of the Arenberg Forest, the Zipp 303 NSW Carbon Clinchers are the lightest and strongest 303s yet. An updated ABLC™ SawTooth™ dimpling pattern provides even better aero efficiency and crosswind stability, and ImPress™ graphics make an aesthetically subtle but significant upgrade performance-wise by printing the logos directly onto the wheel so the work of the aerodynamic dimpling is unaffected unlike with traditional wheel decals.
It's not just the rims that passed through The Nest's speed-multiplying program either. The 24 front and rear Sapim CX-Ray spokes are laced to an improved Cognition™ Disc hubset that features uses Axial Clutch™ technology that reduces drag by using a magnet-operated 36-tooth freehub mechanism that disengages when coasting. It also features star-shaped flanges out back along with a scalloped hub shell on the front that serve to reduce the loads placed on the bearings for extended longevity and smoothness. And, since the Cognition Disc hubs feature Center Lock rotor compatibility, you'll be able to stop on a dime, scrub speed at the last second, and perfectly maintain your position through corners with ease in all terrains, and all conditions.
Includes Zipp Tangente Quick Release Skewer, individual wheel bags, tubeless valves (factory installed), tubeless rim tape (factory installed), valve core removal tool, Cognition thru-axle caps to fit 12x100, 15x100, and 12x142 dropouts, Cognition oil, and a 11-to-10 speed freehub body spacer.
