Zipp 858 NSW Carbon Tubeless Disc-Brake Rear HG
Zipp’s 858 NSW Carbon Tubeless Disc-Brake wheelset uses Total System Efficiency (TSE) technology to improve efficiency and reduce rolling resistance. It features a tubeless and hookless rim profile, a 23mm internal rim width, and an undulating 82mm–85mm deep Sawtooth rim design with Hyperfoil nodes and a HexFin ABLC dimple pattern for aerodynamic efficiency and crosswind stability. The wheelset is designed for road, triathlon, and time trialing, with a premium ZR1 SL hubset featuring ceramic bearings and 66 points of engagement.
The 858 NSW is optimized for tubeless tires and is fastest with a 28mm tire. It also offers the option to use tubeless-ready tires with tubes. Disc brakes provide speed modulation and braking power in all weather conditions, while the wheelset includes 12mm front and rear end caps and a Center Lock rotor interface with lockring included.
