Another day of wheels (and so on).
I built Nomu Lab Wheel #4.
The front wheel is a 4-spoke lacing per the customer's request.
Speaking about this particular hub and rim combination:
With 20H 4-spoke lacing, it's not the spoke that's final-cross with the counter-spoke, but rather
the counter-spoke running opposite to the spoke's elongation direction (clockwise neighbor in this case)
lines up with the spoke to look almost straight.
If you isolate just one section, it forms almost a five-pointed star shape,
which means these spokes are extending in nearly tangential direction.
Since there's no chain engagement and this is a front wheel without a hub-brake,
there's no point discussing spoke drive efficiency,
but if this were a rear wheel with TB-25 rim and 20H,
4-spoke lacing would be where the spoke and its tangential direction align most closely.
You'd never find such a small-flange hub on the freewheel side, but
from a radian perspective, that five-pointed star section caught my attention, so
I thought I'd write about it.
For the rear wheel:
24H Yonroku Italian lacing.
All spokes front and rear are full Campagnolo.
