Zipp wheels are designed for speed, and the Cognition hub is the heart of that system. Upgrade every bearing in your Zipp Cognition hubs to Grade 3 silicon nitride ceramic with DLC-coated races. The reduced friction compounds with Zipp's aero profile — fewer watts lost at the hub means more of your power goes to forward motion. Compatible with both Cognition V1 and the newer V2 platform.
