Campagnolo does not sell equipment direct to consumers. Only branded
clothing and tchotchkes.
Nor does Shimano.

fuck 'em.
My LBS doesn't support the home mechanic. They don't have
much in the way of higher-end new parts in stock and
generally aren't willing to source them: "I'll have to call
the warehouse, if we have it, it will take a few days to get
here."
Another annoying point is that they aren't open past 5 pm
and are closed on sundays. Makes it kind of hard for someone
who works full time to get to the shop.
They do a bang-up business on low/mid range repairs though.
Every time I have managed to get into the shop they have a
substantial back-log of repairs and I've never seen fewer
than 2 mechanics working on the bikes. On saturdays they
usually have 3-4 people working on bikes.

If there's a piece of fine wire in the tire repairing the
inner tube will not prevent a flat a few minutes later.
Fine wire is very common in our asphalt, which is made of
recycled truck/car tires (plus other stuff). It's the tires that have
those nasty stainless steel wires.
I always run my finger round the inside of the tire before
replacing the repaired inner tube. I usually simultaneously find the
culprit and puncture my finger..

He blamed bidens economic policies for creating an economic depression
in california such that "nobody" could afford new tires and "everyone"
was driving around on tires so worn that the belts were fraying and
littering the roadways with bits of steel wire.
https://groups.google.com/g/rec.bicycles.tech/c/eAEXNTV6WKg
I stand corrected, first he blamed obama:
"During Obama and his Great Recession that the Stupid 4+1 don't believe
was there hero Obama's fault, pe3ople without work would run their tires >until the steel casing broke through and would bleed steel particles all
over the road causing bicycles endless problems with flat tires almost >constantly. This did NOT stop until Trump entered office and then
disappeared almost overnight."
Note how the mere presence of trump in the whitehouse magically made all >those wire shreds disappear "overnight".
_THEN_ he blamed Biden
"Biden trumped Obama by doing the same thing in three years."

Ouch. I use a small cotton ball for locating splinters. It should
also work for steel wires.
Examples:
<https://www.bikeforums.net/17442640-post6.html>
(from Sheldon Brown): <https://www.sheldonbrown.com/flats.html#tireinspection>
I'm not quite ready to become a believer but it's a start.
I ran some crude tests to see what it would take to manually force a
thin wire through a bicycle tire and tube. I started with the wire perpendicular to the tire. If the wire was to thin, it would buckle
as soon as it touched the tire. Same if the wire arrived at an angle,
same buckling.
A heavier wire would buckle less but unless the wire was really stiff,
it would not break the surface of the tire. I could almost push a
sharpened bicycle spoke through the tread, but anything that was
moderately flexible would buckle before penetrating. If someone has a
way to demonstrate how a wire from an automobile tire might penetrate
the bicycle tire and tube, I want to try it.
The use of recycled tires for Rubber Modified Asphalt (RMA) was also mentioned. Supposedly, the steel is removed from the shredded tire by magnetic separation:
"Maximizing metal removal in rubber tire recycling" <https://www.recyclingproductnews.com/article/33699/maximizing-metal-removal-in-rubber-tire-recycling>
"Steel-belted tires a source for flats" <https://rayhosler.wordpress.com/2016/05/15/steel-belted-tires-a-source-for-flats/>
"A vibratory feeder feeds rubber crumb onto a high intensity magnetic
field of the head pulley, pulling out tiny wires that may still be

A heavier wire would buckle less but unless the wire was

I can tell you from personal experience that tiny wire bits
do in fact manage to work their way through a bike tire. I
get at least one flat a year that way.

Well, you can actually SEE the wires in our asphalt. Since
they outsource road maintenance in Sao Paulo to private firms, they
probably cut corners to win the bid.
I only get punctures from those wires when my tires are really
bald. I don't think they can penetrate newish tires. Haven't had a
puncture since I last changed tires.

Tom has complained about wire flats before. He blamed it on Biden.
[]'s
Biden had his own sins but I'd bet we wasn't driving around on auto
tires worn through until the steel wires shred. Not in Oakland at any rate
He blamed bidens economic policies for creating an economic depression
in california such that "nobody" could afford new tires and "everyone"
was driving around on tires so worn that the belts were fraying and
littering the roadways with bits of steel wire.
https://groups.google.com/g/rec.bicycles.tech/c/eAEXNTV6WKg
I stand corrected, first he blamed obama:
"During Obama and his Great Recession that the Stupid 4+1 don't believe
was there hero Obama's fault, pe3ople without work would run their tires
until the steel casing broke through and would bleed steel particles all
over the road causing bicycles endless problems with flat tires almost
constantly. This did NOT stop until Trump entered office and then
disappeared almost overnight."
Note how the mere presence of trump in the whitehouse magically made all
those wire shreds disappear "overnight".
_THEN_ he blamed Biden
"Biden trumped Obama by doing the same thing in three years."
On the upside, he does have a very vivid imagination. His
dreams now must be like Paradise, with Trump fixing all the things
that make being poor unbearable.
A world with no flats, no hunger, no inadequate welfare
checks, plenty of cheap or even free food, housing and medical care
etc... You have to envy that.

they are made in the same factory that produces the Paselas I usually

one of them? Perhaps finer casing thread? What else?
I'd love to see cutaway cross sections comparing his tires with Paselas,

as soon as it touched the tire. Same if the wire arrived at an angle,
same buckling.
A heavier wire would buckle less but unless the wire was really stiff,
it would not break the surface of the tire. I could almost push a
sharpened bicycle spoke through the tread, but anything that was
moderately flexible would buckle before penetrating. If someone has a
way to demonstrate how a wire from an automobile tire might penetrate
the bicycle tire and tube, I want to try it.
The use of recycled tires for Rubber Modified Asphalt (RMA) was also
mentioned. Supposedly, the steel is removed from the shredded tire by
magnetic separation:

"Steel-belted tires a source for flats"

"A vibratory feeder feeds rubber crumb onto a high intensity magnetic
field of the head pulley, pulling out tiny wires that may still be
embedded in the crumb rubber material. This results in an extremely
pure product."
Well, you can actually SEE the wires in our asphalt. Since
they outsource road maintenance in Sao Paulo to private firms, they
probably cut corners to win the bid.
I only get punctures from those wires when my tires are really
bald. I don't think they can penetrate newish tires. Haven't had a
puncture since I last changed tires.

For Sao Paulo, video of police chases show amazingly smooth
well maintained streets. No frost cracks/heaves probably
help, but still I noticed them. Not perfect but better than
most US cities.

Nice supple road tyres are obviously somewhat different,

from glass, as it’s route does include the flyover if not
the underpass.
It seems obvious that thicker tread rubber would be less
susceptible to flats.
The remark about "nice supple" tires leads me to ask: Does
anyone have direct experience with the "supple" tires Jan
Heine sells? I suspect they are made in the same factory
that produces the Paselas I usually use. If so, what exactly
are the differences? Is thinner tread rubber one of them?
Perhaps finer casing thread? What else?
I'd love to see cutaway cross sections comparing his tires
with Paselas, and perhaps with other brands and models.
Yes, those are made by Panaracer.
Yes, Panaracer offers several fabrics of various materials
and dernier.
Their new improved USA web pages don't have a section on
casing styles any longer:
https://www.panaracerusa.com/pages/about
Further information on the Japanese pages:
https://panaracer.com/en/news/
with various fabrics for different model tires here:
https://panaracer.com/wp/wp-content/uploads/2024/05/panaracer2024.4_EN.pdf
including TufTex, Agile-F, ASB (anti snake bite), AX-alpha
extra fine fabric, 400D extralight and 800D extra tough fabric.
and for some models, 'anti-flat' bands under the tread in
PR, TF, and ProTite.
with treads in carbon, silica, some gradiated (soft outside,
firm center) models.
In short, what you seek in tire features is not universally
what all other riders seek. Weight, price, cornering at
speed, traction in mud, tread longevity, puncture
resistance, reflective sidewall, resistance to crappy
surfaces or lack thereof and more.
