It's wheels again today (and so on).
I built the front wheel for Nomu Lab Wheel #1.
Evolite hub, 24H, black CX-RAY in 44-Italian lacing,
with silver aluminum nipples.
This is one of the "65×24=78×20 projects,"
and originally I planned to build it with a CX Sprint in 20H,
but the stock shortage dragged on so long that I switched to CX-RAY in 24H instead.
If you only consider "spoke specific gravity × number of spokes" without accounting for spoke length,
a 24H CX-RAY and a 20H CX Sprint have the same total spoke weight.
Even if I were to build this wheel with CX Sprint,
I'd planned to use tangential lacing anyway,
but with radial lacing, if the rim and hub are the same, the spoke length doesn't change,
so the actual weight difference of the spokes only comes down to "spoke specific gravity × number."
With tangential lacing, the spoke length changes slightly between 20H and 24H,
so technically you should compare using "spoke specific gravity × number × length,"
but for rough estimates when considering wheel characteristics,
you can ignore the length difference without problems.
Also, even with radial lacing, 20H and 24H naturally have 4 more nipples,
but with 12mm aluminum nipples,
the difference of 4 pieces is only about 1 gram, so there's no reason to worry about
"the rim weight getting heavier!" That much.
Individual variation in rim weight is actually larger than that.
Back when I thought Sapim CX Sprint would be consistently available,
orders I received for rim brake front wheels in full CX Sprint
or disc brake front wheels in half CX Sprint,
I often change the specs—the former increases the number and uses CX-RAY,
and the latter goes full CX-RAY with cross-lacing on both sides—
but for projects like "rebuild a previously made 20H rim brake front wheel to disc brake spec"
using a 20H disc brake front hub, I have several of those on hold,
and I think even full CX-RAY with cross-lacing on both sides might be tight on spoke count,
so those are waiting for CX Sprint stock to arrive.
When building a disc brake front wheel in half-Competé or full-Competé 44-lacing,
if the disc brake caliper connection uses
a banjo hose joint style (like SRAM brakes),
there's a high probability that near the final crossing of the four-spoke Competé lacing
(depending on hub dimensions) the banjo bolt head will interfere.
If that's not an issue, half-Competé is fine too.
By the way, I've also seen this issue occur on
complete bikes from KONA that came stock with full 14-gauge plain 66-lacing wheels
(the brake was SRAM Force), and when you stand on the pedals a bit,
the spokes rattle against the banjo bolt,
so I once rebuilt just the left side of the front wheel.
I don't know how other shops handle this situation.
