A customer brought in the rear wheel of a Nomu Lab Wheel No. 5 (custom wheelset).
There was a bent spoke from derailleur wrap-around damage,
and they wanted it replaced and inspected.
↑In addition to the derailleur wrap damage,
there was also a spoke deformed from a chain drop.
Fixed.
I was given discretion on which spokes to replace,
and I replaced a total of 4 spokes.
↑The replaced spokes
The topmost spoke in the previous image
appears to be the one spoke that took
the full shock of the derailleur wrap alone.
The second spoke from the top is
one that took the chain drop impact, and has deformation,
but it also had splintering, so I replaced it. The third and fourth spokes from the top had no deformation,
but showing some marks from the chain drop, so I replaced them as a precaution.
Next, a separate job:
A customer brought in the rear wheel of a Nomu Lab Wheel No. 5.
The hub is a PowerTap G3, and this is the second rim for this hub.
We relocated the rim at that time,
but reused the spokes. The non-drive side CX-RAY has broken at the thread start point.
This wheel is built 28-hole four-cross,
and with this pattern (especially with small-flange hubs like evo-lite hubs)
there are cases where spokes break at the point where the drive-side spoke overlaps the non-drive-side spoke head,
and when that happens, the non-drive side is often re-built to six-cross. However, since this breakage is at the rim,
I decided to handle it by replacing only the broken spoke section. Since it's laced, I'll replace it along with the matching spoke in the final cross pair.
↑This is a non-drive-side spoke replacement,
but if you loosen the nipple of the overlapping drive-side spoke sufficiently,
the replacement that seems impossible becomes possible.
Got snagged.
Alright, it fit.
Fixed.
The two replacement final-cross spokes. I'll do the lacing later.
The spoke whose nipple I loosened temporarily for the spoke replacement. I loosened it 8 turns and tightened it 8 turns,
and otherwise fixed it with barely any other adjustments.
↑The replaced spoke Cut after releasing the tension.
The spoke broke at the thread start point.
The hub end of the spoke,
↑Top image is drive-side spoke, bottom is non-drive-side.
This is a drive-side spoke, and the scuff mark visible near the center of the image is the contact point with the non-drive-side spoke head.
