More wheel work today (and so on).
Continuing from yesterday.
I'm lacing the front hub's non-rotor side radially.
With disc rear hubs, the right side experiences freewheel body twist,
and the left side experiences brake braking twist,
so neither can be laced radially.
With a disc front hub, the right side should be doable,
which is why it's being laced radially,
but since we're further lowering an already low-tension side,
it's not theoretically a great lacing method.
The front rim is the same as yesterday's rear rim,
so I've reversed the offset (apex shifted right) to correct the tension difference,
but the spoke lacing method ruins that.
Plus, the rim had shifted pretty far toward the rotor side (left side).
Like the rear wheel, both sides are loose,
so just tightening up the left side for centering isn't enough—
both sides need tightening.
The final cross on the left side creaks when you grip it lightly,
and the right side's radial lacing is all wobbly,
so I'm wondering if this front wheel behaves differently in right corners versus left corners.
Of course, if you said that about any disc hub front wheel,
theoretically it should be true, but with this much left-right difference and looseness,
the behavioral difference might actually be noticeable to the rider.
If this had been an inspection instead of a rebuild,
I'd say this front wheel was pretty poorly built.
The radial runout was also terrible.
But since we're taking this wheel apart anyway, it doesn't matter.
Got it built.
24H black CX-RAY 64-spoke reverse Italian lacing.
While the dish isn't quite as extreme as the rear hub,
with left-right different diameter same spoke count,
I didn't quite reach the point where the spokes on the flatter side become higher tension
(meaning the spoke tension difference reverses).
I was thinking of going with half-comp no cross or full CX-RAY with cross,
but the difference is close enough that crossing doesn't seem necessary, so no cross.

↑After rebuild
Today both wheels have no rim tape, so this is pure wheel-only weight difference.
