Zipp 858 NSW Tubeless Disc Brake Wheelset

Zipp 858 NSW Carbon Disc Wheelset

Zipp’s ultimate speed weapon, engineered for triathletes and time trialists

The Zipp 858 NSW is built to push aerodynamic boundaries, combining cutting-edge Total System Efficiency (TSE)technology with a lightweight, high-performance carbon construction. Featuring a hookless, tubeless-compatible rim profile and a wide 23 mm internal width, this wheelset enables the use of wider tires at lower pressures—reducing rolling resistance while improving ride comfort and speed.

Aero mastery meets real-world stability

With its undulating 82–85 mm deep Sawtooth™ rim profile and patented Hyperfoil™ nodes, the 858 NSW delivers elite-level aerodynamic efficiency while enhancing crosswind stability. Ideal for triathletes, time trial riders, and any speed-focused cyclist, it offers deep rim benefits with a weight more typical of shallower wheels.

Lighter, faster, and more refined

Weighing approximately 1500 grams, the latest 858 NSW is 30 grams lighter than the previous model. Optimized for 30 mm tires, but at its fastest with a 28 mm tubeless setup, it gives you the freedom to ride tubeless or with inner tubes. The lower tire pressures not only reduce resistance but also keep your body fresher for the run in triathlon settings.

High-end performance from hub to rim

At the core is the ZR1 SL hubset, equipped with ceramic bearings and a fast-engaging 6-pawl freehub (66 points of engagement) for responsive power transfer. The wheelset is laced with CX-Ray spokes and Sapim Secure-Loc nipples, while Zipp’s signature ImPress™ direct-print graphics provide long-lasting aesthetics without compromising aerodynamics.
