Upgrade your wheels with a CeramicSpeed wheel kit to reduce friction, increase performance and get the most out of your hubs. The Zipp-4 upgrade kit fits for Zipp wheelsets from model year 2014 and forward, with Zipp 88 front and Zipp 188 v9 rear hub.
The kit includes 4 x 61803 and 2 x 61903 ceramic bearings for one front and one rear hub.
CeramicSpeed wheel bearings have a proven lifetime which is 3-5 times longer than standard wheel bearings, reducing the need for bearing maintenance.
The high velocity of wheel bearings means that bearing friction can have a huge impact on performance. A CeramicSpeed wheel kit reduces friction. The result is higher speed with the same effort and a higher top speed. You will feel the difference immediately.
Every single bearing is hand built in Denmark under clean room conditions. All parts are selected by hand for perfect fit, each bearing is spun by hand multiple times during the building process to ensure that all parts are matched perfectly.
CeramicSpeed balls are smoother, harder and lighter than the standard steel balls which are typically used in bicycle components.
Installation Hint: Add grease and mount seals before installation, necessary parts included.
