ZIPP Ceramic Speed Bearing Kit - 61903 - ZIPP 30/60 Rear Hub Shell
WASTE NOT, WATT NOT In the never ending quest to make athletes faster on their bikes, Zipp is constantly testing and refining. As you pedal your bike, there are a known set of resistive forces continually stealing energy away from your athletic efforts. One of these forces is drivetrain friction. To achieve the perfect balance of performance, durability and cost, Zipp hubs are machined to the closest tolerances possible and are supplied standard with steel bearings of the highest grade available. But, for cyclists looking for that extra advantage, Zipp has partnered with CeramicSpeed to create specific ceramic upgrade bearing kits for use in all Zipp hubs and free hub driver bodies.
