We sold a Bora WTO 45 DB at our shop.
Currently, all Bora WTO models come in 2-WAY-FIT specification.


The wheel bag appears to have changed starting with the 2020 model.

First, the rear wheel.


It looks like it's shifted ever so slightly toward the non-freewheel side.
But this is perfectly centered.

The hub axle end is the silver, tapered section,
and the black part is the bearing preload adjustment locknut.
The silver side protrudes slightly and has a step,

and that's where it's perfectly centered.
Lateral runout is essentially nonexistent,

and looking at the rim circumference, there's a molding seam on the rim,
and on the rim side at this position, there's a catch so slight
that you can't feel it even running your finger over it—
initially that's where runout was detected, but
otherwise there was hardly any runout at all.

When you shake the rim, it makes a rustling sound.
There are fine bits of carbon debris like thin straw inside,
and even a single piece makes a distinct sound
(though you wouldn't notice while riding),



they're all longer than the valve stem diameter,
so they won't come out with just a light shake.


For removing debris from inside the rim,
I recommend the Hozan P-887 angled-tip tweezers!

Ignore that sudden promotion and on to the front wheel.


The provisional center shows a slight offset.

↑Unlike the rear wheel, this is an actual center offset

The reason it's "provisional center" is because the customer wants
only the front wheel converted to CULT (it's currently USB).

The Bora WTO's drum-shaped hub shell has a cone that's difficult to remove (poor tool engagement),
which I've mentioned before, but
the hub for disc brake use is even more pronounced in this regard,

and removing the cone on the non-rotor mount side is extremely difficult.

I removed the USB bearing.
USB is an acronym for Ultra Smooth Bearing,
so USB bearing would be "Ultra Smooth Bearing bearing,"
but we shouldn't dwell on that.
Since it's a new wheel,
I'll degrease the ceramic ball retainer and reuse it for CULT.


When I press-fit the cone, assemble the hub, and apply the center gauge,
the amount of offset clearly changes.
I checked the provisional center and didn't true and center before converting to CULT
because I expected this would happen.


First phase center offset correction...

The background isn't white so it's hard to see, but needs a bit more


I trued and centered the wheel.
Lateral runout was more than the rear wheel.

The included tubeless valve is short relative to the rim height, but

a valve extender is also included,

and the threaded section cut into the extender

is full threads across the length extending from the rim,
so there's no problem with mounting the valve nut.
