A customer left a carbon tubular rear wheel with me.
This is a rear wheel I had previously rebuilt with radial spoking on the non-freewheel side.
The question was whether I could transfer the spoke set as-is to a different rim with the same rim height (though not necessarily the same rim inner diameter),
Since it's the same manufacturer's rim with the same nominal rim height,
and my measurements showed the rim inner diameter differing by only 0.2mm in diameter (0.1mm in radius),
spoke reuse is possible.
A 0.2mm difference in diameter is probably just measurement error anyway,
so the rim inner diameter before and after rebuilding is probably the same.
So why rebuild it at all?
↑One reason is that the brake zone developed bulging from heat damage caused by Swissstop's Yellow King brake pads.
After switching to their Black Prince pads after this,
the thermal deformation symptoms in the brake zone stopped progressing,
but that's closing the barn door after the horse has bolted.
The other reason is that I wanted to switch to a wide rim (approximately 25mm width).
This rim is only about 22mm wide, and the tire bed has a tight curve to it,
so it's not ideal for mounting wider tires,
but since the customer is using 25C tires,
a wide rim makes more sense in that regard.
From years of use, I noticed the rim had shifted slightly toward the freewheel side.
If this were just a routine truing check,
I'd be done with just tightening up the non-freewheel side spokes.
But beyond that, there was a pretty significant lateral runout,
and some spokes had been bent from hitting something.
It's built.
This is a transfer of what looks like a Leaf hub, 24H, black half-comp, 4-cross lacing with tie-wires,
but since I replaced the non-freewheel side spokes,
I need to re-tie the final crossing without the tie-wire.
It's now a wide rim, but it still has a tight curve.
Depending on the tire, the rim tape (called "fundoshi," named after WO's rim tape but a different product)
visible between the rim and tire is almost completely hidden.
One CX-RAY spoke was bent, but since it's tie-wired,
I had to replace its partner in the final crossing as well.
The comp spoke on the freewheel side between them was also slightly bent.
If the CX-RAY hadn't been bent, I almost certainly wouldn't have noticed it.
