Experience the future of cycling with the Zipp Cognition Freehub Body, where unmatched stability and stiffness redefine your wheel's performance. Engineered with precision, this hub showcases Zipp's revolutionary Axial Clutch mechanism, elevating your cycling experience to new heights.

At the heart of the Axial Clutch mechanism are two Metal Injection Molding (MIM) ratcheting rings, one integrated into the freehub body and the other in the hub body. These uniquely designed rings engage and ramp off each other, mimicking a ratchet system. As a result, they reduce friction while freewheeling, ensuring that your coasting doesn't nullify the power you've already exerted. Unlike traditional pawl designs, the lateral engagement of the MIM rings sets the Cognition Freehub Body apart, providing a smoother and more efficient ride.

Zipp takes innovation a step further by replacing the conventional steel springs with magnets, resulting in an even greater reduction in friction between the ratcheting rings. This groundbreaking improvement sets a new standard for mass-produced hub sets, delivering unparalleled smoothness and performance.

Zipp once again leads the charge by introducing this cutting-edge design. Step into the future of cycling with the Zipp Cognition Freehub Body and revolutionize your riding experience with its remarkable technology and unparalleled performance.
