Another day working on wheels (you know the drill).
A customer left me the front and rear wheels from their Nomu Lab Wheel No. 5 for repair.
They purchased it about five years ago, but a spoke on the freewheel side of the rear wheel snapped, so they're asking for a fix.
The front wheel just had a slight wobble in a couple of spots.
Didn't even bother taking a photo of that one.
Like the image at the top, this is already after the repairs.
So while I was dialing in the true,
I noticed one side was clearly pulling sharply inward at a certain point,
and when I looked closer, there was visible deformation in the bead hook.
↑Right here
Using a straightedge, it looks like this
So I'm replacing the rim.
The blue nipple in this shot is the same one from the previous image.
Looking at the deformed spot from the side,
the braking zone wasn't particularly whitened.
So the deformation happened pretty recently.
That's because when the outer rim of the bead hook gets bent inward like this,
with extended use the parts that don't contact the brake shoes won't show wear marks,
so the indentation becomes more obvious over time.
Also, just to be clear here,
I absolutely did not, following orders from some executive trying to inflate repair costs,
use a sock filled with a golf ball—basically a blackjack-style bludgeon—
to beat the rim sidewall.
However, there are definitely some ten-legged executives forcing us to include stickers with their likeness packed in with wheels,
and carnivorous executives pushing sales at prices that border on predatory dumping under the guise of "festivals."
↑The replaced spoke
It snapped on the rim side, not the hub side (the spoke's neck),
and the break happened not at the start of the spoke's threads
but at the start of the threads on the inside of the nipple.
Before disassembling the wheel, after replacing the spoke,
I did maximum truing,
and when I held a brand new rim up to it to check the early deformation,
it looks like this.
The rim's moving day...
Got it built up.
I've replaced the blue aluminum nipples as well.
If the original wheel was built less than a year prior,
sometimes I'll reuse the old ones.
P.S.:
I also replaced the bearing on the left side of the hub body.
