Another day, another wheel (you know the drill).
I built the front wheel for Nomu Lab Wheel #4.
I deliberately chose the old Evo hub in 24H.
It's leftover inventory because the specs suddenly switched to the Evo Lite hub.
The spokes are CX-RAY with inpoke radial lacing.
The Evo Lite front hub is about 25g lighter than the old Evo front hub,
but the weight savings from the flange drilling that's visually striking in the Evo Lite design
are actually pretty minimal.
If you ignore the density difference between aluminum alloy and pure aluminum,
drilling out the volume of a one-yen coin would save you about 1g,
but even if you add up all the drilling on the Evo Lite hub,
you'd be lucky to reach the volume of a single one-yen coin.
The major factors in weight reduction are the smaller bearings
and mostly come down to the reduced diameter of the hub shell and shaft.
For the tire, I glued on a Corsa CX Elite that I'd been hoarding with rim cement.
Back when this tire was the latest model,
the standard choice for road bikes was 21C width for tubulars or 23C for clinchers,
but nowadays for some reason both of those have shifted up by 2C in popularity.
Vittoria and others had the Corsa CX tubular available in multiple colors only in 21C,
with 23C and 25C in all-black only as far as I recall,
but now the multi-color options are 23C,
and 21C and 25C are all-black exclusive.
This makes me feel like "the recent wider tire boom is being manufactured by the companies"...
Carbon rims have also gotten wider out of concerns about buckling,
with wider models becoming the mainstream.
There might be some harmonization happening with that.
(With ZIPP Firecrest and SMART ENVE,
aerodynamics is given as the reason,
but wider rims are becoming standard even on models without especially tall rims,
so they must be conscious of buckling resistance)
You might notice from the mention of "hoarding" this tire
and the fact that this article isn't in the "Nomu Lab Wheel" category,
so I should mention it: this is my personal bike. Sorry about that.
