Overview

The Zipp 858 NSW D1 Rear is built for speed on flat and rolling terrain, pairing Zipp’s deepest NSW rim with a wide internal profile and modern low-pressure tire philosophy. Under Zipp’s Total System Efficiency (TSE), the 23 mm internal width is designed for wider road tires at lower pressures, cutting aerodynamic drag, rolling resistance, and vibration losses on real roads.

Rim & Tire System

The 858 NSW uses a tubeless-only, hookless carbon rim with a minimum 28 mm tire requirement. Zipp’s pressure table lists a maximum of roughly 72 psi (5 bar) for 28 mm and 65 psi (4.5 bar) for 30–32 mm; most riders will choose lower working pressures for the best grip and efficiency. The undulating Sawtooth profile (about 82–85 mm deep) with Hyperfoil nodes and HexFin ABLC dimples manages airflow to reduce steering torque and keep the bike calm in gusts.

Drive & Braking

This Zipp 858 NSW D1 rear wheel rides on Zipp’s premium ZR1 SL Center-Lock hub (12×142 mm) with a quick-responding 66-point engagement mechanism. Driver bodies are available for XDR and SRAM/Shimano cassettes, with Campagnolo options sold separately. Braking is rotor-based only; there’s no rim brake track.

Who it’s for

Time-trialists, triathletes and speed-focused road riders who want the stability of Zipp’s Sawtooth aero shaping in a deep rear wheel that’s optimized for 28–32 mm tubeless tires and modern pressures.
