Another wheel day (and so on). But first.
I swapped the rear rim on Nomu Lab Wheel No. 5.
This falls under an unwritten warranty claim,
so it's not really the kind of thing I usually write about here, but—
Since I had to swap the rim anyway,
it doesn't really count against today's wheel quota anyway.
Evolite hub, 24H, black half-comp valve holes on both sides only,
silver spokes, 46-spoke lace, blue aluminum nipples.
And now for today's actual wheel build—
I had to build Nomu Lab Wheel No. 5 today,
but this other one had to take priority.
It's a front wheel on a Prime through-axle disc hub, and
the customer tried to do some truing themselves,
so the nipples are cracked and stripped all over the place.
They asked if I could fix it.
It's an aluminum rim, but it has OEM markings.
The rim with a brake zone is labeled AT01,
and the disc-brake-specific version (offset rim with no brake zone)
is called ATD01, apparently,
but both of these seem to be model numbers for Prime's wholesale,
and there's no retail market for them as standalone products.
However, there are AT470 and ATD470 rims,
which look remarkably similar to AT01 and ATD01 respectively.
I'll have to check whether they're actually the same thing.
↑Cracked nipple
↑Stripped nipple
I thought replacing all the nipples—which is essentially a wheel build—would be enough, but then—
The rim seam was peeling, so it needed to be replaced too.
Built it up.
I used an AXIS-brand rim from a Specialized complete bike we had in stock—
it had almost the same rim inner diameter (so the spokes could be reused).
The original lacing was all black CX-RAY, equivalent to a straight 44-spoke pattern.
I removed the spokes from the cracked nipples,
and found 2 bent spokes while disassembling.
The customer had brought along spare spokes that came with the wheel—
exactly 3 of them—so I used them all up.
Interestingly, this front wheel was built with the same spoke length on both sides,
ignoring about a 1mm difference left to right,
and the spare spokes were also all the same length for both sides.
After rebuilding, I used black CX-RAY straight lace on the rotor side
and outpoked on the non-rotor side.
So I gave the customer the leftover black CX-RAY straight spokes—
12 of them—which they can use as spares for the non-rotor side.
Incidentally, before the rebuild, neither side had the final cross woven in.
Prime apparently intentionally does this (probably for noise control):
they don't weave the final cross on either side of the front wheel
or the non-freewheel side of the rear.
↑Spokes I replaced (the 2 bent ones)
When you use the rim as your reference for parallel—
—the hub looks like this.
Since I completely disassembled and rebuilt this front wheel,
it technically meets my wheel-building criteria,
but that's beside the point—I absolutely had to deliver on the title.
So anyway, I built Nomu Lab Wheel No. 5.
Front wheel: Evolite hub, 20H, CX-RAY outpoke radial lace,
Rear wheel: Evolite hub, 24H, half-comp 46-spoke lace,
Gold aluminum nipples.
I'll do the lacing later.
