Zipp 858 NSW Carbon Tubeless Disc Brake Rear Wheel 700C Center Lock XDR 12x142mm

Experience unparalleled speed and aerodynamic efficiency with the Zipp Wheel - 858 NSW Carbon Tubeless Disc Brake Center Locking 700C Rear. Engineered for serious cyclists, this wheel combines cutting-edge Total System Efficiency™ technology with an innovative tubeless, hookless rim design to minimize weight and maximize performance. The 23mm internal rim width allows for wider tires at lower pressures, reducing rolling resistance and enhancing ride comfort without compromising speed. Whether you're competing in triathlons, time trials, or aggressive road rides, the 858 NSW sets a new standard for performance and durability.

The distinctive 82mm-deep Sawtooth™ rim profile, featuring Hyperfoil™ nodes and HexFin ABLC dimples, offers superior aerodynamic benefits and exceptional crosswind stability. This unique rim shape balances aero efficiency with stability, allowing you to maintain control and speed even in challenging conditions. At its core, the Cognition V2 hubset with Axial Clutch V2 technology ensures rapid engagement, low friction, and improved longevity, delivering smooth power transfer whether pedaling hard or coasting. Finished with Zipp’s ImPress direct-print graphics, this wheel is as visually striking as it is technically advanced.

What It’s Good For

• Maximizing aerodynamic speed in triathlon, time trial, and road racing scenarios
• Reducing rolling resistance through wider tubeless tires running at lower pressures
• Enhancing crosswind stability with the Sawtooth™ rim profile for confident handling
• Providing quick hub engagement and efficient power transfer via Axial Clutch V2 technology
• Offering durable, lightweight carbon construction with a hookless rim design for seamless tire fit
• Compatibility with disc brakes and center lock rotors for modern braking performance
• Easy tire installation facilitated by the optimized tire bed design
• Ensuring long-term reliability backed by a lifetime warranty

What It’s NOT Good For

• Use with non-tubeless tires, as the rim is designed exclusively for tubeless compatibility
• Applications requiring rim brake compatibility, since this wheel is disc brake specific
• Riders needing wider than 27mm maximum tire width, which exceeds the rim’s outside width limit
• Users requiring Campagnolo driver bodies, as these are sold separately and not included
• Heavy off-road or mountain biking use, as the wheel is optimized for road, triathlon, and time trial disciplines
