Waste no Watts!
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 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 Zipp hubs and free hub driver bodies.
