I received a Bora WTO33
rim brake wheel from a customer.
They want an inspection and tubeless tire installation.
For the front wheel, they asked me to take steps to avoid
the new hollow axle catastrophic failure issue.
When I loosened both end nuts with a 5mm Allen key
the right side came loose first.
This is a sign of the hollow axle problem, so
I'm going to use threadlocker adhesive to fix
the relationship between the hollow end bolt and hub axle on this side.
I applied a custom-made 14mm spanner wrench to the right side
and loosened the left end nut.
After applying grease to the threads and tightening,
I tested multiple times with 5mm Allen keys on both sides,
and now the left end nut tends to loosen first.
There was no centering issue.
I only touched the nipples at two spots
to make very minor spoke tension adjustments.
Now for the rear wheel.
The rim is slightly offset toward the freewheel side.
In my way of expressing it, about two sheets of paper.
I centered it.
There was almost no lateral runout.
I installed Schwalbe Pro One TLE tires.
TLE is an acronym for Tubeless Easy, which
Schwalbe uses because they want to avoid the term "tubeless ready"—
though it means the same thing as tubeless ready.
This tire has labels on both sides at 180° phase angles.
The tire has a tread pattern and a specified rotation direction,
which I follow, but when centering the phase directly below the valve
on the label center, having two labels doesn't mean
both would be the same...
When following the rotation direction specification, there's only one
TLE label on the left side.
I installed the tires so this label's phase aligns
with the valve hole phase on both front and rear wheels.
When viewing the wheel from the left side with the valve at the top,
the valve position is at 12 o'clock on a clock face,
but the TLE label will be at 3 o'clock or 9 o'clock.
The idea is to align them as either 3 o'clock to 3 o'clock
or 9 o'clock to 9 o'clock, and this time I went with 3 to 3.
In the image above on the left, the bead at the phase of
the rear wheel's TLE label doesn't appear to be seated, but
↑Front wheel
↑Rear wheel
on both tires, all the way around
there's a "you can only see this line when the bead is seated" mark,
so the bead is seated.
The only difference is the label print position is slightly different.
Also, this wheel has an AC3 brake zone,
so the rear wheel can't be installed wrong,
but the front wheel has directional performance characteristics regarding left and right.
Those salmon-slice-like lines in the image above are it.
