Zipp 858 NSW & Super-9 Disc Time Trial Wheelset

Description

The Ultimate Aero Weapon

The Zipp 858 NSW and Super-9 Disc Time Trial wheelset combines Zipp's fastest deep-rim front wheel with their premier rear disc wheel — a combination favored by triathletes and time trial specialists seeking maximum aero efficiency. Both wheels are built on Zipp's Total System Efficiency (TSE) technology, engineered to conquer the four barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses.

858 NSW

The 858 NSW features Zipp's patented Sawtooth profile — an undulating 82-85mm deep rim shape delivering top aero efficiency and crosswind stability. The hookless tubeless rim profile creates a seamless tire interface and significant weight reduction, giving you the benefits of deep rims at weights typically associated with rims 20mm shallower. The 23mm internal width is ideal for wider tires at lower pressures for decreased rolling resistance. The 858 NSW is built around the premium ZR1 SL hubset with ceramic bearings and 66 points of engagement.

Super-9 Disc

Among the lightest disc wheels available, the Super-9's refined shape runs wide and parallel from the hub until it feathers inward to meet the hookless tire bed. Redesigned from the rim-tire interface to its ceramic bearings, the Super-9 is significantly stiffer and more durable than its predecessor. It comes with an integrated TyreWiz 2.0 tire pressure monitor and a redesigned pump-access port — no stickers needed. Like the 858 NSW, the Super-9 features the premium ZR1 hub with ceramic bearings and 66 points of engagement.
