More wheels today (and so on).
A do-over from yesterday.
I built Nomu Lab Wheel #2.
Front wheel: Evolite hub 20H, CX-RAY spokes, radial lacing,
Rear wheel: Reef hub 24H, semi-comp 46-spoke lacing with cross-lacing.
After a long period out of stock, they finally arrived, so
I suspect that all future rim shipments will be the WH-108 model.
(Unless we special order unusual spoke hole counts like 28H, etc.)
Yesterday's WH-007 was from our remaining inventory before the distributor ran out.
I got a comment asking "Could the WH-108 rim be heavier?" so
I did a quick investigation.
But first.
↑WH-007
↑WH-108
I just noticed today that the new rim has a groove to clear tire seams.
Actually, you could already tell from yesterday's photos.
The rim width is exactly the same when measured with calipers, so
the changes appear to be reinforcement around the valve hole and this groove.
As for weight
↑24H I used today
↑20H I used today
↑Another 24H from inventory
↑Another 20H from inventory
All four are WH-108 (just to be clear).
I didn't deliberately pick out the lightest ones, but
even the heaviest of these four came in lighter than the stated weight.

Hub, spokes, and lacing are all identical, and both weights are after soldering the cross-lacing.
Today's rear wheel is rim weight + 328g as a complete wheel, so
assuming no variance in hub and spoke weight,
yesterday's rim estimated weight would be 335g.
That's well within the margin of error, so there's
no meaningful weight difference between the WH-007 and WH-108.
