Another day working on wheels (and so on).
A customer left me a rear wheel — the tubular rim version of a Dura-Ace C36.
The image above is from after the work.
I had previously converted this from a front wheel to a rear wheel, and since the half-competition spokes were too stiff,
the customer asked me to lower the spoke tension differential.
I switched the drive-side spokes from competition (86.5%) to CX Sprint (78%).
The non-drive side CX-RAY (64.5%) stayed as is.
Since there's no question about how tightly I've dialed in the lateral runout (←if I do say so myself),
I completely disassembled just the drive side, swapped in the CX Sprint spokes,
and tensioned them as tight as possible, but
this was the limit.
The rim has shifted toward the left side (non-drive side).
When near the end of building, tightening the drive side doesn't pull the rim to the right very much,
but loosening the non-drive side moves things a ton.
From here I had no choice but to loosen the non-drive side, so
starting from a state loosened 1/4 turn at a time,
the final fine lateral truing was done by further tightening the drive side.
Got it centered.
Up until the final centering, I barely touched the non-drive side nipples, so that earlier center offset amount
represents the difference between half-competition and half-CX Sprint spokes.
