The Winspace Hyper are highly regarded, they have very good aerodynamic properties and are comfortably one of the fastest wheels you can buy.
The Winspace hubs use standard 6000 series bearings of common sizes. This video shows you how to remove the bearings and replace them if they are worn or you want a bit more speed/durability.
It covers the service of the front hub, rear hub, rear freewheel. The part numbers are shown below.
Additionally, towards the end of the video there is a section covering grease, the merits of thick versus thin and what type to buy.
