I received a Bora Ultra 35 from a customer.
It appears to be unused, but according to the customer it's a 2014 model,
and indeed it is definitely the 2014 model.
As of 2011, the Bora wheelset
only existed in one specification: "50mm rim height / internal nipples / narrow rim (20mm width) / tubular",
and there were only two versions—Bora Ultra Two and Bora One—differentiated by hub and bearing specifications.
In 2012, the Bora Ultra 80 with 80mm rim height came out,
but this featured external nipples / narrow rim and tubular specification only.
Apparently it wasn't a strong seller, and since the cost of new carbon molds
for converting to wide rims couldn't be recouped in sales,
even as of 2018, the Bora Ultra 80 remains in its original specification—
narrow rim and tubular only.
2013 saw the same Bora lineup as 2012.
In 2014, the Bora Ultra 35 and Bora One 35 models were introduced.
At this point, only tubular specification was available.
Since the 50mm model continued unchanged,
they were called Bora Ultra Two and Bora One rather than Bora Ultra 50 or Bora One 50.
This original Bora 35, like the 80, featured a narrow rim with external nipples.
In 2015, the 50mm model
became the Bora Ultra 50 and Bora One 50,
with external nipples and a 24.2mm wide rim specification.
The Bora Ultra 35 and Bora One 35 also became second generation,
with external nipples carried over from before, but wider rims.
At the same time, clincher specifications were introduced.
So narrow rim carbon clincher wheels
only exist in the Hyperion line—there are none in the Bora line.
In other words, the narrow rim 35mm Bora
only exists in the 2014 model.
With current models, Bora One rims are not sold as spare parts.
You can repair with Bora Ultra rims,
but since Bora Ultra rims and Bora One front wheels cost about the same,
no one actually does that.
With current Bora Ultra rims, stickers are already applied
and under clear coat, so they can't be removed.
However, with the 2014 Bora 35, the rim without stickers
was shared between Bora Ultra and Bora One, with separate stickers applied as needed.
This is also a feature unique to the 2014 model.
The WARNING sticker was on the left for the rear wheel and right for the front wheel.
Since the front hub shell had no stickers or directional markings,
I removed the hub axle and changed it to left-side WARNING.
Front wheel perfectly centered!
Rear wheel perfectly centered too!
Almost no runout at all.
The valve rattle prevention guard, also known as
valve bush WH-BUU002, was the newer tube type
rather than the old claw type.
This is plausible for late 2014.
Campagnolo changed the WH-BUU002 part number from the claw type to the tube type without updating the number itself,
but as I've written before, apparently they felt some embarrassment about this
(in fact, the valve is harder to insert), and deliberately didn't change the part number
to make the claw type disappear as if it never existed.
For example, if they'd made the tube type WH-BUU003,
you could choose between old and new when ordering,
but by keeping the same part number, no one would deliberately buy the old type,
and gradually only the new version would be in circulation.
However, during this period there were cases where "the new type came on the wheel,
but when you ordered spare parts, the old type arrived,"
which was troublesome.
The customer also asked me to install Continental Competition 19 tubulars.
The valve was just the right awkward length that you couldn't add air without an extension.
The accessory bag that came with the wheel had no valve extender,
so I used a generic one with the shortest available length.
