Another day on wheels (and so on).
I built the Nomu Lab Wheel #2.
Front wheel: Evolite hub 20H CX-RAY reverse-Nupo spoke radial lacing,
Rear wheel: Evolite hub 24H semi-comp 46-lacing.
Since the customer is on the lighter side weight-wise,
they requested spoke nipples without doubling (no bracing),
but with wheels I've built, it's possible to brace them later if needed.
About the rim I'm using on the Nomu Lab Wheel #2,
separate from the conventional 19.1mm width version,
a 23.8mm wide rim specification came out not too long ago.
Around the same time, the 19.1mm rim was discontinued,
and it's been tweaked to 20.5mm width.
The old #2 rim had a decent stock here at the shop,
but we've used those up, so from this point on it's the new #2 rim.
The new rim's claimed weight is 340g for the front with 18/20H hole counts,
and 336g for the rear with 24/28H hole counts,
but there's no way you can precisely manufacture a 4g difference like that,
so in cases like this I think it makes more sense to just say 340g across the board.
Either way, it's all official specs anyway.
The actual average measured weight is 347g for the old rim (WH108),
and about 376g for the new rim (WH199).
For the new rim's weight, while not based on a sufficient sample size,
it feels like less than 20% come in under 360g.
The old rim's tire seating surface has a tight curve,
so it's somewhat unsuitable for mounting 23C and wider tubular tires,
but personally I prefer the lighter old rim.
Since it's been discontinued rather than sold alongside the new one, there's not much point dwelling on what's gone.
When swapping to other wheels, you need less brake adjustment clearance,
it suits fatter tires, it's stronger against buckling—
it's true the new rim better matches current road bike conditions.
Also, going forward, even the Nomu Lab Wheel #2 built with the new rim
will keep the same name.
Calling it the "new" Nomu Lab Wheel #2
starts and ends with this article's title.
