Rear wheel: R45 hub, 24H, all Champion, 3-cross lacing with no center cross.
Even though it's all Champion,

I used #14 on the freewheel side,

and #15 on the non-freewheel side, creating an asymmetric build.
Due to spoke length requirements, whether round or flattened,
butted spokes are hard to source, so I went with plain gauge spokes.

The nipples are brass.
For spoke truing alone there's no issue,
but when spoke replacement becomes necessary, you need to remember that
the nipple sizes differ alternately.

As mentioned in the title, at 38mm depth this carbon WO rim
has an actual measured weight of 311g,
with a stated weight of 320g.
By the way, I forgot to mention something important about this rim,

it's a 20-inch WO rim with an ETRTO of 451mm.
