A customer left me a Bora One 35 Bright Label clincher for work.


They want the USB hub converted to CULT and a general inspection.

I removed the USB bearing

from the hub.

↑The CULT is what goes in the One, and the USB is the retainer bearing by itself.
The wheel isn't brand new but hasn't seen much use,
so this time I'll reuse the retainer bearing and just swap out the One and the cone.


↑Centering was off by about the thickness of a sheet of paper


Fixed it.

Now for the rear wheel.

↑The new ceramic ball laying diagonally across the top of the bearing,
and the two original ceramic balls below it.
I decided to reuse these as well.

The pawl spring is fine,

but when I spun the rim I heard a noise,
and had a tough time guiding the foreign object out through the valve hole.

I cleaned the removed One and cone,

and returned them to the customer.

The valve bush was missing,
and they asked me to replace it,

so I installed a new one.

Right now the shop only has the older two-pawl type in stock,
but since the front wheel has the old type, the specs match.


Same customer, one more job.
This one's a Dark Label clincher.

Yep, new shaft complete disaster case.

From the right side the "USB marking on the hub body is backwards"
and doesn't match the rear hub either, so
when I install the shaft later I'll flip it the opposite way.

Jumping ahead in the timeline, but this is what I did.

I removed the One.

I'll reuse the retainer bearing.

Not that it matters, but the 50mm-tall one has a new valve bush.

I forgot to snap a photo of the rear hub One after removal.

↑USB Ones and cones and seals for both front and rear

I'm returning these to the customer as well.
This time I'm doing CULT One and cone swap only, not the full CULT bearing kit,
but frankly, this approach isn't the most cost-effective.

I've listed the set pricing and individual item pricing (tax-included MSRP)
for Campagnolo's new front small-diameter bearings.
The denominator is the set unit, the numerator is the tax-included MSRP.
The white-seal HB-BO021 (1354/4) isn't listed in the diagram above,
but it's almost certainly reusable so no problem there.
In this case I did swap it out,
but I didn't charge the customer for it.

I've added the unit price in red.
With a difference this small,
if you had, say, a brand new unused USB wheel to convert to CULT,
you'd actually save money buying the bearing kit
rather than picking up the One and cone individually.
In this job, I adjusted the price
so the customer wouldn't overpay.
Our shop's current limited stock situation (looks like it'll continue for a while)
makes that possible.
Also, if you're converting a pair of wheels where the front has new bearings to CULT,
the individual-purchase option comes as 4 parts per set,
meaning you'd have 2 parts left over after the work.
Very few shops seem to sell individual pieces from set-packaged parts at per-piece pricing,
so individual purchasing is tough from that angle too.
