Wheels again today (and so on).
A do-over from yesterday.
Built Nomu Lab Wheel #2.
Front wheel: Evolite hub 20H, CX-RAY inpoke radial laced,
Rear wheel: Leaf hub 24H, semi-competition 4-cross laced with spoke ties and solder joints.
After a long backorder, stock finally arrived, so
I'm guessing all future rims we get will be WH-108.
(Unless we special order uncommon hole counts like 28H or something)
Yesterday's WH-007 was from our shop stock before the distributor ran out.
I got a comment saying "WH-108 rims might be heavier—suspicious," so
I looked into it a bit.
But first.
↑WH-007
↑WH-108
I just noticed today that the new rim has a small depression for tire seam clearance.
You can actually spot the difference in yesterday's photos too.
Rim width checks out perfectly with calipers, so
the changes appear to be valve hole area reinforcement and this depression.
As for weight
↑24H used today
↑20H used today
↑Another 24H from our stock
↑Another 20H from our stock
All four are WH-108 (just to be clear).
I didn't deliberately pick the lightest ones,
but among these four, even the heaviest came in under the spec weight.

Hub, spokes, and lacing method are identical, and both weights are after spoke ties and solder joints.
Since today's rear wheel came to rim weight + 328g,
assuming no variance in hub and spoke weight,
yesterday's rim would have weighed approximately 335g.
That's well within the margin of error, so I don't think there's any meaningful weight difference between WH-007 and WH-108.
