The Zipp V2 NSW Disc/Rim Brake Campagnolo Freehub Kit converts Cognition V2 NSW rear hubs to accept Campagnolo‑pattern road cassettes, letting you swap drivetrains without replacing your wheelset. The aluminum freehub body comes with bearings and a seal installed and fits both disc and rim‑brake NSW wheels (including 353, 454, and 858 NSW models). It’s specified for Generation 2 Cognition hubs (serial 21P8 and higher) that use the one‑piece axle system, and is rated for Campagnolo 10/11/12‑speed cassettes (retailer listings also show backward compatibility to 9‑speed). Riders on Campagnolo’s 13‑speed Ekar platform should instead use the separate Campagnolo N3W driver made for Cognition V2/ZR1 hubs.
