ZIPP 858 NSW Rear Carbon Tubeless Disc Brake Wheel D1 – Aerodynamic Road Racing

The ZIPP 858 NSW Rear Carbon Tubeless Disc Brake D1 is a pinnacle of aerodynamic engineering and lightweight performance, designed for road cyclists, triathletes, and time trial specialists seeking every advantage on the course. This wheel features Zipp's proprietary Total System Efficiency (TSE) technology, which combines an innovative tubeless and hookless rim profile to reduce weight dramatically while maintaining exceptional tire compatibility and ride quality. With a 23mm internal rim width, the 858 NSW supports wider tires at lower pressures, optimizing rolling resistance and enhancing comfort without sacrificing speed.

Its signature Sawtooth rim shape, undulating between 82mm and 85mm in depth, is specifically engineered to maximize aerodynamic efficiency while improving crosswind stability—a critical factor for maintaining control and confidence during high-speed rides. The wheelset's premium ZR1 SL hubset, equipped with ceramic bearings and 66 points of engagement, ensures smooth, responsive power transfer and reliable performance. Whether you prefer tubeless or tubeless-ready tires, this wheelset offers versatility without compromise, making it the ultimate choice for riders who demand speed, precision, and durability.

With disc brake compatibility and a center lock rotor interface, braking performance is enhanced in all weather conditions, allowing for consistent modulation and stopping power. The 858 NSW is optimized for 28mm tires, striking the perfect balance between aerodynamics and comfort, especially beneficial in triathlon where every watt and every minute counts. Additionally, the wheelset incorporates Zipp’s ImPress direct-print technology for a sleek, durable finish that reflects the quality and craftsmanship behind this top-tier product.
