Another day of wheels (and so on).
The counterpart to yesterday's front wheel, but like the rear wheel,
I'm swapping out the hub for a different one.
With the AL22W rim—it's a disc brake rim—
this technically becomes Nomu Lab Wheel #8,
so I've recategorized both this article and yesterday's under "Nomu Lab Wheels,"
but this wheel was originally built about 2 years ago on July 12, 2020,
and back then I didn't classify this rim's wheel as Nomu Lab Wheel #8.
Since it's a hassle, I'm not going to change the category on that old post.
FH-M975, 32H, all-comp, 4-6 JIS lacing, no radial lacing.
This customer is probably the one I've built the most wheels for
on an individual basis.
I've built so many wheels for them that I've lost count,
and at one point I even asked something like "are you really using all of these yourself?
(are you perhaps brokering wheels for friends or something?)"
They said they use them all themselves.
By the way, I don't mind brokering and that's fine with me.
For wheels that aren't competition-oriented,
they request aero spokes not be used, silver-colored spokes, and no radial lacing,
so when previous builds had used radial lacing, I can often reuse spokes since that's now not required.
The AL22W rim does come in offset versions,
but when I build disc brake wheels,
I often use non-offset rims.
With front wheels that have minimal dish, if you do left-right different-diameter different-count lacing,
the right side spokes get so tight they practically sing.
This is why rims like the DT RR411db that only come in offset are actually harder to build.
In the past, semi-comp was the best option available,
but nowadays if you use semi-CX sprint lacing,
the left-right difference in spoke tension is reduced,
so it doesn't become as strong a wheel as semi-comp.
With this customer's wheel as received,
the condition is no aero spokes, so it's all-comp.
As it happens, for left-right different-diameter lacing with round spokes,
there are options like Champ/Comp or Strong/Comp.
By the way, Dura-Ace hubs don't accept Strong spokes through the flange holes, but XTRA does.
Since we're building it all-comp with no radial lacing,
both front and rear wheels this time are built with offset rims.
This is what makes the next rear wheel difficult.
The rear hub I'm using for the swap is
from a Surly single-speed,
the right side has the fixed cog mounting interface,
and the left side has a 6-bolt disc rotor mounting interface.
This rear hub's flange on the disc rotor side
is positioned more inward. In other words, it has reverse dish.
So if you build the offset rim in the normal way
with the rim holes leaning toward the left side,
the left-right difference in spoke tension actually increases.
And flipping the rim around won't make the tension equal either.
I'll write about this in the next post.
Like the front wheel, I'm making sure that the rebuild doesn't change
which spokes are pulling and which aren't.
Built.
32H, all-comp, 4-6 JIS lacing, no radial lacing.
Someone might ask why 4-6 lacing was necessary,
but I prioritized reusing the spokes.
Like the front wheel, the new hub after the swap had a larger flange
and required shorter spokes,
but the difference wasn't enough that the 4-spoke lacing on the XTRA freewheel side
versus the 6-spoke lacing possible on the Surly hub would justify a different pattern,
so it ended up as 4-6 lacing.
↑Wheel right side
↑Wheel left side
I've oriented it opposite to the normal way you'd orient an offset rear wheel rim.
As a result, while the right side does have higher tension,
it's closer to the left-right difference you'd get on a standard rear wheel built with a freehub
using left-right same-diameter same-count lacing.
