Another wheel day (and so on).
I received an Araya Aero 4 rim from a customer.
Seems like there are still some out there in certain places.
I do have the same rim myself, but mine are 24H and 28H.
With these spoke hole counts, I definitely don't have one.
The rear hub is a Powertap PRO that I have on deposit.
Just to be clear, it's brand new.
And just to be extra clear,
it's not being sold in this condition (of course it isn't).
Something's already been done to it, but don't mind that.
Got the rear wheel built.
The spokes are semi-comp, laced in a 4-cross pattern.
A 8-cross lace wouldn't work.
Since there's no way around it, I'll mention this:
spokes of 315mm length are required.
With radial lacing, the spoke length is (the length component when viewed from the side)
determined simply by subtracting the hub flange diameter from the rim height.
In terms of spoke length, the rim height and hub flange diameter are effectively equivalent values.
With tangential lacing, things change.
As the hub flange diameter approaches zero, the spoke path becomes closer to radial lacing,
and when it reaches zero, it becomes the same as radial lacing—
but this time it's the reverse.
With a large flange, the spokes actually become longer.
The condition for spokes to be shorter with radial lacing is
"high rim / large flange,"
but with tangential lacing it's
"high rim / small flange."
That said, the main reason I couldn't lace the non-drive side with 8 spokes this time
isn't so much the hub flange diameter but rather the large inner diameter of the Aero 4 rim itself.
When I looked into it, even if it were a G3 hub (with a slightly smaller flange than the PRO hub),
the spokes would end up being an unobtainable length.
Got the front wheel built too.
