Zipp Z3 & Z4 wheels use these bearings in their hubs at zipp.com. These are ISO 6001 hybrid ceramic bearings (12mmx28mmx8mm) that can be bought for around $25-35.00 each at most bearing supply companies, maybe cheaper if you really look. The same bearings go in HED 3 as well. I found that different companies state the the bearings run 30% to 50% faster. Anyone one have experience with the Z4 in comparison to the Zipp 404 or a ceramic engineering degree to help with this topic.
Bottom line if you spend 100.00 on bearings are you really gaining anything?
