A customer brought in the rear wheel of Nomu Lab Wheel #5.
There was a spoke that got bent when the rear derailleur was pulled into the wheel,
and the customer wanted it replaced and the wheel inspected.
↑Separate from the derailleur pullover,
there was also a spoke that got deformed from a dropped chain.
All fixed.
I was given the call on which spokes to replace,
and ended up replacing 4 spokes total.
↑The replaced spokes
The top spoke in the previous image
is the one that I believe took
the full impact of the derailleur pullover alone.
The second spoke from the top is
an inpoke that experienced the dropped chain impact, and does show deformation,
but there was also fraying, so I replaced it. The third and fourth spokes from the top showed no deformation,
but there were signs of the chain drop damage, so I went ahead and replaced them just to be safe.
Moving on to another job:
A customer brought in the rear wheel of Nomu Lab Wheel #5.
The hub is a PowerTap G3, and this is the second rim for that hub.
When we swapped rims,
I reused the spokes. The non-freewheel side CX-RAY has broken at the thread start.
This wheel is a 28-hole 4-cross lacing,
and with this pattern (especially on small-flange hubs like Evolight),
there are cases where inpokes and outpoke heads overlap and cause breakage at that point.
When that happens, we usually rebuild the non-freewheel side as 6-cross.
But this time the break is on the rim side,
so I decided to handle it by just replacing the broken spoke section. Since it's tied in, I'll replace the paired spoke in the final cross with new ones.
↑This is an outpoke replacement, but
if you loosen the overlapping inpoke nipple sufficiently,
what looks impossible at first glance becomes possible.
Got stuck.
Yes! It seated.
All done.
The two final cross spokes that got replaced. I'll tie them in later.
The spoke whose nipple I loosened temporarily for the replacement. I loosened it 8 turns and tightened it back 8 turns,
and everything else stayed pretty much untouched, so it all came together nicely.
↑The replaced spoke I cut it after releasing the tension.
Broken at the thread start of the spoke.
The hub end of the spoke,
↑Top image is inpoke, bottom is outpoke.
This is an inpoke, and you can see the scuff mark near the center of the image—
that's where it contacts the outpoke head.
