Another wheel day (and so on).

Built a rear wheel using a hub and rim the customer brought in.
The rim is a PLANET X (high-end carbon tubular rim brand) 50mm deep carbon tubular rim.


Evolite hub, 20H, half-comp (semi-competitive) four-cross lacing with spoke nipple connections.

I inspected a front wheel built with the same rim and PLANET X hub,
and it had centring issues with extremely low spoke tension.
It wasn't that it had loosened over time — it was slack from the start.
Just tightening one side to correct the centering wasn't enough tension,
so I tightened both sides, but what bothered me was that the spoke length was clearly too short.
Since the hub is PLANET X, it appears to be exactly as the manufacturer ships it.
On top of the centring adjustment, I turned the nipples just over two full rotations,
which means I advanced the spoke threads by two pitches,
but even so, in relation to the nipple, the spokes are on the short side.
They haven't reached the slot yet.
Anyone who's built wheels knows this, but
with a properly tensioned wheel, you simply can't turn the nipples another two rotations tighter from there.
