Zipp CeramicSpeed Bearing Kit 61803x2
If you have Zipp's 88/188v8 hubs and you want to upgrade your bearings to CeramicSpeed's fantastic hybrid (ceramic balls, steel races) sealed cartridge bearings, this is the kit you need. Two 61803 bearings are included. Each pair will replace one hub- front or rear, and also work for the 188 freehub body, so if you want to upgrade your entire wheelset and freehub body, you will need to buy three kits.
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 there is ample research that shows us that you can save anywhere from 1-9% watts by upgrading. Some of the variables are overall condition and maintenance of old and new bearings, and frankly, your hub adjustment.
Reduce friction, save watts, and roll smoothly with Zipp and CeramicSpeed by upgrading your wheels and freehubs. It is an investment, but if you are already Zipp's incredible aero carbon wheels, you are likely ready to push all the chips in, and CeramicSpeed can deliver the edge you need to completely maximize your abilities and overall investment.
