CeramicSpeed Ceramic Wheel Kits - Zipp 4 Info

With this Zipp 4 CeramicSpeed Ceramic Bearing Kit, your 88 front and 188 v9 rear hubbed Zipp wheels will be even faster than they already are.

CeramicSpeed bundles six bearings into this kit, so you can upgrade your Zipp wheels in one move. In CeramicSpeed nomenclature, this is Zipp-4. Even with the name, you are getting six bearings: two for the front hub, two for the rear hub, and two for the cassette body.

Wheel bearings can make a big difference on performance. Up to nine watts can be saved here, and that means you’ll go faster for much less effort.

CeramicSpeed utilizes Grade 3 Silicon Nitride balls that possess the best possible surface finish and roundness. In testing, the balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls found in most bike components. They’re more than 100% smoother and 15% harder than standard ceramic balls. The balls are installed into hardened steel races in dust-free clean rooms and then checked again before assembly is complete. Not only is low friction the result, but so is increased bearing life. Like three to five times longer than standard bearings.

If you replace all your bike’s bearings with CeramicSpeed, you could be looking at a savings of 25 seconds in 40km if you’re riding at 48kph. The savings goes up to two minutes if you’re riding at 32kph. Extend that to an Ironman-length ride, and the savings could vary from 1:50, if you’re going 48kph to nine minutes if you’re going 32kph.

Another step they take in assuring the lowest-possible frictional drag is using grease they designed as lubricant. It comes in the bearings and a syringe comes with the bearings as well.

The kit comes with the six bearings, seals, grease, and sticker sheet.

The CeramicSpeed Ceramic Bearing Kit for Zipp 2014 and on wheels means that the same kind of attention lavished on rim shaping is given to reducing bearing drag.
