ZIPP COGNITION NSW DISC BRAKE Front/Rear 61903 Bearing (x2) #11.2018.052.002

The ZIPP Cognition NSW Disc Brake 61903 bearing kit is the official service kit designed for front and rear hubs on Cognition NSW disc brake wheels. It allows you to replace the original bearings when they develop play, noise, or reduced smoothness after multiple seasons of hard riding.

Sold as a pair in 61903 size, this kit restores the precise, buttery-smooth rotation characteristic of Cognition hubs. Installation requires the appropriate press tool for ZIPP hubs (sold separately) to avoid excessive stress on the bearing races.
