The 454 NSW Carbon Clincher Disc-brake delivers aerodynamic efficiency and crosswind stability that far surpasses conventionally shaped wheels with the superior modulation and stopping power of disc brakes. The 454 NSW’s undulating 53/58mm-deep rim shape takes cues from some of nature’s most elegant design solutions and combines them with engineering precision for unrivaled durability and performance while delivering a level of AeroBalance unlike any wheel ever made. Zipp engineers have optimized the biomimicry-derived 454 NSW for the ultimate in all conditions braking control—disc brakes. This marks the first NSW wheelset available for disc brakes, offering cyclists the greatest AeroBalance with the superior modulation and stopping power of disc brakes. It is the ultimate mid-depth wheel for all-around road performance. - Hyperfoil - Cognition Disc-brake hubset - ImPress graphics - HexFin ABLC dimple pattern - Carbon Clincher - AeroBalance - Handcrafted in the USA
