Built a Wheel with the New Barcelona 92 Rim

Another day of wheels (and so on).

I've taken in a Campagnolo Barcelona 92.
It's one of the last two hand-built rims that Campagnolo ever produced.

Campagnolo had an old rim series called the Greek Letter Series.
The final flagship model would be the Sigma, I think,
but there were various others like Lambda, Omicron, and Omega.

After that came the Olympic Series,
and while the flat-profile Omega existed,
there was the Omega V model—a triangular-section aero rim (as it was called back then),
and the Omega V came in both tubular and clincher versions.
The clincher Omega V and the Moscow 80 are identical except for the stickers.
This is the only connection between the Greek Letter Series and the Olympic Series.
The Olympic Series includes
Rome 60, Mexico 68, Munich 72, Montreal 76,
Moscow 80, Los Angeles 84, Seoul 88, Barcelona 92,
Atlanta 96 (some labels say Atlanta 1996),
and Sydney 2000,
but I've never actually seen a Tokyo 64.
Also, I've never seen an actual Rome 60.
(Though images come up if you search for them)

These were sold continuously without any specification changes, but
ultimately the rim specs were consolidated to
"the front rim from Campagnolo's Nucleon (originally without eyelets, 22H)
converted to a single-eyelet 32H rim and sold as a rim alone,"
and released as
Montreal 76 for clincher and Barcelona 92 for tubular.
That's what we have here.
Since both the Montreal 76 and Barcelona 92 have completely different profiles from the original rims of the same name,
in my spoke length calculation formulas I use the names
New Montreal 76 and New Barcelona 92 for convenience.

↑Labels like this are
DSC03832amx3.jpg
applied in alternating directions on almost opposite sides.
This isn't a mistake—they all come like this.
With Campagnolo's Greek Letter Series,
the Campagnolo logo label and rim name label were applied in alternating directions,
so they're following that tradition.
At first glance it looks like there's no front or back,
but these two labels are positioned near the valve hole and near the rim seam respectively,
so there is a distinction.
So...

DSC03834amx3.jpg
When the rim seam is placed at the bottom,
the rim name reads in the correct direction, and
DSC03835amx3.jpg
looking up at the valve hole from there,
the Campagnolo logo also reads in the correct direction—
I decided to build it so both front and rear face the right side when moving forward.

DSC03837amx3.jpg
It has a trapezoidal profile that closely resembles Mavic's Reflex,
DSC03838amx3.jpg
but while the Reflex has double eyelets, this one has single eyelets.
(Double eyelets are originally a Mavic patent, by the way)
Perhaps for that reason, it actually weighs around 380g—quite a light rim.

The hub I have on hand is a Campagnolo.
This is "probably" a Centaur.

↑The image above is a 2007 Centaur, the one below is a 2007 Veloce.
As stated in the catalog, these two are identical except for the quick release lever.
Campagnolo used to do this often—if it said Mirage, it was Mirage,
if it said Veloce, it was Veloce,
with differentiation only in the dust seal marking.

The Centaur before this used cup-and-cone bearings like Record and Chorus,
and could be retrofitted with cartridge bearings compatible with the later CULT,
but from 2007 onward it switched to the cartridge bearing hubs of the lower-tier models,
sharing most of its specs with Veloce.
That's why I wrote "probably" Centaur earlier.

DSC03844amx3.jpg
The mystery is the quick release.
This probably isn't the original accessory for this hub.
It's basically a Fulcrum lower-tier model quick release with just the Campagnolo logo,
but it's somewhat of a rare piece because it only came with the 2007 Vento or Camsin.

Shimano does this too, but
there's the principle of "silver hubs with silver quick release, black hubs with black quick release,"
which this violates.

↑This is the quick release that came with a 2009 Racing 5,
and at Fulcrum this quick release design was used for a long time.

Okay, time to build the wheel already.

Built.
Front wheel first.

DSC03864amx3.jpg
32H, fully butted, Italian laced (all 6/6).

DSC03852amx3.jpg
DSC03855amx3.jpg
The rear wheel is 32H, fully butted, laced 4/8 with no lacing wire.
It's a tangential lacing, though not a true tangential,
so the spoke head contact with the opposite flange is minimal.
As I mentioned earlier, the dust seal has no hub grade marking on it.

DSC03848amx3.jpg
DSC03849amx3.jpg
The front hub flange wasn't dished toward the rim at all.
This is a bit unusual.
Setting aside Campagnolo's ban on radial lacing,
if we were to prioritize avoiding spoke-flange interference,
reverse-radial lacing would be the optimal solution.
(Of course, we don't actually make such trivial matters our top priority.)

DSC03851amx3.jpg

↑The rear hub's non-drive side flange has a noticeable dish,
while the drive side is less pronounced, so they're clearly accounting for the eight-speed spacing
and dishing the flange toward the rim accordingly.

DSC03862amx3.jpg
DSC03860amx3.jpg
So the front hub has spoke heads actually touching the flange,

DSC03858amx3.jpg
DSC03859amx3.jpg
but with the rear hub, they're just barely not touching.
The minimal interference mentioned earlier with the spoke head is probably a factor here too.
Though the contact itself isn't inherently problematic,
a perfectly straight hub flange is just unusual enough to notice.
