Another wheel day (and so on).
I want to build the rear wheel, which is the match to yesterday's RR411db rim front wheel,
but first, I'm taking care of this one.
I received a rear wheel from a customer's Prime complete wheelset.
The rim is that ATD01 I mentioned,
but the bead hook is buckled and dented in.
Even with this deformation, the tubeless tire maintained air pressure without leaking
(of course with sealant inside),
so the customer didn't notice the rim was bent—
they thought it was just running a bit out of true.
But when they took the tire off, this is what they found.
Since the DT RR411db rim has similar width and weight, I'm rebuilding with that,
but I'm keeping the rear hub as-is.
Prime RD010 straight-spoke hub (6-bolt exists too, but this one is center-lock)
24H, all-black CX-RAY straight spokes in a 2-cross pattern on both sides,
on the freewheel side, the final cross is braided,
and on the non-freewheel side, it's not braided.
There were a couple of bent spokes.
The RR411db rim has a larger inner diameter,
so the spoke length is longer—I can't reuse the old spokes anyway.
The original spokes were 297mm on both sides, and I thought that was lazy work,
but it turns out it wasn't.
Based on my measured hub and rim dimensions, the theoretical calculation gives
297.2mm freewheel side and 297.83mm non-freewheel side,
so using the same length on both sides is within tolerance.
I cleaned the outside of the hub.
Built it.
RD010 hub, 24H, black half-spokes, 2-cross pattern on both sides with lacing.
Since it's a straight-spoke hub, I can't change the build pattern.
The non-freewheel side has quite a small flange,
so the final cross is close to the hub flange, and the lacing effect is minimal,
but when I tried it, it made a real difference.
The customer got to see the difference in tightness between the braided lacing (before soldering) and no lacing at the final cross.
Plus, without lacing, the wheel is already stiffer than before the rebuild even without soldering.
Next, I built another RR411db rear wheel with a different hole count.
This is the match to yesterday's front wheel.
FH-RS770, 28H, black half-spokes in Campagnolo 4-cross JIS pattern.
I'll do the lacing later.
I forgot to mention, but on the Prime hub rear wheel rebuild, unlike before,
I braided the final cross on the non-freewheel side.
Or rather, I can't do lacing without braiding it.
