Another day with wheels (and so on).
I built a wheel using a Nosetubes Grail rim.
It's a cyclocross wheel for the same customer who ordered the Iron Cross rim.
Front wheel: Tni disk hub 28H black, CX-RAY, 6-cross reverse Italian lacing,
Rear wheel: Tni disk hub 28H black, half-radial Leader and 4-cross JIS lacing with cross-bracing.
The customer asked me if we could use a spoke equivalent to Champion rather than Competition on the freewheel side, since reverse high-low was too demanding for these hub dimensions. I got their approval.
I chose Sapim Leader spokes for the freewheel side because black 14-gauge plain spokes are more readily available than DT's Champion spokes.
For silver spokes, I would go with Champion.
Yeah, it really is completely different from half-radial.
Unless the hub has some very unusual dimensions, different-diameter lacing is more "effective" than different-side lacing,
and this was truly significant.
If we express the left-right difference in spoke count and spoke weight ratio, ignoring the lacing method and length on each side, as left:right,
for a typical 2:1 laced wheel (except exceptions like Zonda),
it becomes 1:2 and 100:100.
With half-radial, this becomes 1:1 and 65:85. If we ignore the lacing method and spoke length
(or assume it's a front wheel with radial lacing on both sides),
and multiply these two factors to express the "quantity" ratio of spokes left to right,
the spoke quantity difference on a 2:1 wheel becomes 50:100.
This is equivalent to the spoke quantity when the non-freewheel side uses super-lightweight spokes with 50% spoke weight ratio in a same-number lacing pattern.
(Though if such spokes actually existed, undulation would be unavoidable.)
Starting from a wheel where left-right spoke weight is the same in 2:1 lacing
(like Racing Zero),
if you split the non-freewheel side spokes cleanly in half, like splitting a chopstick,
to create a same-number spoke wheel,
that becomes a wheel with 50:100 spoke quantity.
The rear wheel this time is Leader/CX-RAY, so
with same-number spokes on both sides, the spoke quantity is 65:100, and
even though spoke count is the same left and right, the tension correction degree
comes quite close to 2:1 lacing.
That said, this is in comparison to ordinary wheels,
and if we're talking about correction degree alone, different-spoke-count lacing is still superior.
Furthermore, in reality, the dish and reverse high-low add as negative factors, and
these are "stronger" than the correction degree of different-spoke-count lacing that we ignored in the spoke quantity discussion, so
tensioning the non-freewheel side is very difficult with this hub dimension.
What actually happens if you build it normally,
I touched on in my article from when I built the Iron Cross the other day.
That's been a real learning experience.
