Another day with wheels (and so on).
I took in the rear wheel of Nomu Lab Wheel #5.
It was built with a Dura-Ace 24H hub, all CX-RAY spokes, 46-spokes laced, with spoke twisting connections,
but the request was to rebuild it as a semi-competition wheel.
Rebuilding without unwinding the connections on the non-freehub side
is something I can do—I know the procedure because I originally built this wheel—
but given that it's been used for around 40,000 km combined for brevets and commuting, plus it has a history of a spoke breakage repair,
I decided to do a complete spoke replacement to be thorough.
So I loosened the tension sufficiently before disassembling.
The rear brake hadn't been used much, apparently, because
the braking zone showed minimal wear relative to the mileage, and
the rim showed no distortion (not a gap anywhere when checked against the pseudo-surface plate glass window),
so I decided to reuse the rim.
I cleaned the hub.
New Dura-Ace hubs with aluminum large-diameter shafts (7800 series and later)
have a shaft rotation that's smooth and cloudless, but with a weight
like kneading honey. It seems the bearing has seated in,
because the smoothness remained but
the rotation became considerably lighter.
There's a risk of mistaking grease starvation for bearing seating, so this requires careful attention.
Finished building.
Semi-competition 46-spoke laced wheel with spoke twisting connections.
Same as before the rebuild—I went with gold aluminum nipples.
（The nipples themselves were replaced with new ones）
