Zipp 858 NSW Carbon Tubeless Rim Brake 700c Front Wheel

Zipp’s ultimate aero weapon is now tubeless ready. That means you get the many aero advantages of the 858 NSW Tubeless rim-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The wheelset’s 19mm internal width is optimized for running wider tires at reduced air pressure. The 858 NSW’s undulating 77/82mm-deep rim shape, our proprietary Sawtooth™ profile, takes design cues from nature for our highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil™ nodes, that reduces both aerodynamic drag and side force. Simply put, the 858 NSW Tubeless is ideal for those focused on triathlon, time trials, or aggressive road riding.

Key Features:

• New Zipp graphics and cosmetic identity that screams speed, applied using Zipp’s ImPress™ direct-print technology.
• 19mm internal width and tubeless compatibility for optimization of wider tires with lower tire pressure
• Cognition hubset rolls efficiently whether you are pedaling or coasting. Its Axial Clutch™ technology allows the freehub’s ratcheting mechanism to deliver half the mechanical drag of conventional three-pawl hubs.
• Sawtooth™ rim with Hyperfoil™ nodes and HexFin™ ABLC dimple pattern for top aero and crosswind-stability performance with an undulating 77/82mm rim depth
• Industry leading Showstopper™ brake track: powerful and consistent braking, even on the wet
• XDR™ or SRAM/Shimano driver bodies
• Ships with QR end caps, quick release skewers
• Campagnolo driver body sold separately
