Two brake adapters, an axle assembly, and a hub body are needed to assemble a hub, even if brakes will only be installed on one side.

An axle assembly consists of an axle, 2x M10-1x45mm bolts, 4x M10 washers, and 2x 6905 bearings you can use shielded sealed or open bearings. 

The hubs are a straightforward assembly. When lacing your wheel bolt, the hub end adapters employ M5 x14mm socket head cap screws.
