ZIPP 858 NSW Carbon Tubeless Disc Brake D1

The Zipp 858 NSW Carbon Tubeless Disc-brake wheelset is the ultimate aero weapon, engineered to be faster than ever through proprietary Total System Efficiency (TSE) technology. Designed for triathletes, time trial specialists, and speed enthusiasts, this wheelset features a tubeless and hookless rim profile for a seamless tire interface and a significant reduction in weight. By optimizing the wheel for real-world conditions, TSE technology helps you conquer the four barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses.

The undulating 82mm-85mm deep rim shape features the patented Sawtooth profile, Zipp's highest-performing design for aerodynamic efficiency and crosswind stability. Combined with Hyperfoil nodes and the HexFin ABLC dimple pattern, the 858 NSW delivers a smooth, fast ride even in unpredictable winds. With an internal width of 23mm, these wheels are optimized for running wider tires at lower pressures, which decreases rolling resistance and smooths out the ride to keep your body fresher for the long haul.

At the heart of the wheelset is the premium ZR1 SL hubset, featuring ceramic bearings for minimal friction and 66 points of engagement for immediate response. Disc brakes offer reliable speed modulation and stopping power in all weather conditions, while the ImPress direct-print technology applies graphics directly to the rim, allowing the dimples to do their job effectively.
