Your cleats are supposed to be adjusted so that the shoe does NOT contact the toe-clip. When using shoes without cleats, it was quite common to wrap some tape around the toe-clip where the shoe would contact it and that was done precisely to prevent wear on the toe of the shoe.

Good story. Sadly, these are the parts that stood out the most for me.

"she switched to the local park, Flatwoods, near her home in Tampa, Florida, to complete a 7-mile loop over and over again"
"as Amanda had suffered a serious brain injury whilst cycling in 2011 when a car hit her at 50mph. Flatwoods wasn’t the only place she cycled, but it helped the family keep an eye on her, as even in Flatwoods she was being pestered by men while on her bike."
"After my crash, I wasn’t sure that I would ever cycle again (Amanda was left with a broken leg, a back injury that eventually led to surgery, cartilage and tissue damage, deep bone bruising, hip, knee, ankle and foot injuries and a Traumatic Brain Injury)."

Her riding was done between May 2016 and mid 2017. "pestered by men while on her bike". I am sure glad Trump was in charge during part of her ride to Make America Great Again. We need American men to harass, molest, assault, twenty something age girls on bikes. Trump won Florida electoral votes in 2016 and 2020.

That's the rule for everything. Lacing skins together to get a better
fit wasn't as big an improvment as wearing clothes. The eyed needle
wasn't as big an improvment over lacing as lacing was over just using
the fabric the way you found or made it . . .

and improvements after the invention of the zig-zag sewing machine are

For most sewing machines, I would agree that progress has been
incremental and not revolutionary. However, in industrial sewing
machines, the introduction of CNC (computerized numerical control)
machines has been revolutionary in terms of what can be done with such
a machine. For example, quilting and embroidery has become heavily
computerized:
http://www.computerizedquiltingmachines.com
I've seen a building full of embroidery machines cranking out
elaborate sports uniforms and hats in different sizes at amazing
speeds. All the material, thread, and fasteners are handled by robot
arms, cut to shape in the machine, and sewn together in a programmed
sequence. The revolution is in the programming, which we don't see in
the final product.

Other possible candidates for revolutionary change might be ultrasonic
stitching, hot glue bonding and paper clothing. These have been
around for several decades, but have not sold well for various
reasons. It's mostly because these changes are visible to consumers
who tend to be very conservative in their choice of material and
assembly techniques and tend to reject anything revolutionary.

Incidentally, if you need a good laugh, look at what's being offered
by the industry as the next big thing in fashion:

Then again ten years ago (perhaps earlier) some people were reusing bicycle inner tubes to make clothing. Talk about recycling.

Err, no, they are just mechanised. Instead of someone having to manually
move the sewing head(actually the spread fabric), they can just feed
commands into the X & Y motors and the thread quilting pattern can be
made very decorative.

My guess is Sanyo. There's one on one of my wife's bikes now. It's fine
for her occasional use.


Correct, a Sanyo Dynapower. I bought it for the Peugeot PR 60/L shown in
the link above with an Union bottle generator. At that time I used the
Peugeot for commuting during sommer and winter, with various lights. I
tried almost everything, and broke almost everything available at that
time.

I'm retired for more than three years now and mostly don't ride in the
dark anymore. But as a backup and because it's the law, I carry an
b&m Ixon Core in my bag and an Sigma Blaze mounted at the seat post.

https://www.bumm.de/en/products/akku-scheinwerfer/produkt/180l%20.html
https://www.sigmasport.com/en/images/sigma_website/produkte/slider/slider_blaze/slider/01_slider_blaze_black.jpg



I tried one of those Sanyo Dynahub roller generators
and did NOT like the beam pattern with the included
light/ That beam pattern was a long T with both portions
of the T being very narrow. Maybe with a different
light it would have been better.


It was. German law (StVO) made a lot of detailed and very specific
technical requirements for biycle lights mandatory, including a
mandatory generator to provide exactly 3 W at 6 V to the light in front
and the taillight. Even the light bulbs needed a specific registration.

For example, this bulb
https://www.mystrobl.de/Plone/radfahren/technik/komponenten/licht/P1050738a.jpg
has the registration number K16429. First hit with DuckDuckGo:
https://www.amazon.de/K16429/s?k=K16429
These still are in use around here, on very old bikes having had no
maintenance since thirty years or so. But most new utility cycles are
sold with hub dynamos and led lights, for many years now.

I initially used a Busch & Müller Lumotec lampe like this one:
https://images.internetstores.de/products/364367[1920x1920].jpg

Requiring registered bulbs in those lamps wasn't entierely moot, because
it guaranteed the neccessary position and size and position of the the
filament and so sensible beam pattern.

Unfortunately, the very same law didn't allow anything else, neither 12
V, nor more than 2.4 W for the front bulb and 0.6 W taillight. That's
not much with a non-halogen light, even with a good parabolic reflector.



I also thought about cutting out a section
of rear fender on my cantilever brakes touring
bike and then mounting the dynamo to
the brake bridge. However the lousy beam
pattern meant I had no interest in doing that.


I switched to an lead acid battery, already mentioned, plus a second
lamp (Lumotec, too) using a different bulb as a full beam - essentially
overvolting by using a compatible bulb having a lower nominal voltage.
Illegal of course, but necessary for my commute.

But brakes have always worked
just fine for the past hundred years. I'm sure recent
improvements are better. But not much better since there
wasn't much to improve.

Well, this is why I don't really like these ****ing contests wrt.
innovations. Sometimes, progress comes in tiny steps, almost invisible.
Anyway, there was a lot to improve. Modern brakes work better when the
rim is wet and have a lot less hysteresis. I guess some of the disc
brake hype comes from people switching from old rim brakes to new disc
brakes.



Awhile ago cars had drum brakes.


Did cars ever have rim brakes?


All cars have disc brakes
now.


Not yet. Our family car still has drum brakes on the rear wheels.

It doesn't matter, cars aren't bicycles.


The old drum brakes worked.


Still do.

I am sure disc brakes are
better. An improvement. A necessary improvement. Yes. But I
don't think it was like we went from rear end crashes on
every single drive to rear end crashes once a decade when
brakes changed from drum to disc. Disc brakes work better
than drum brakes in cars.


Perhaps. I believe that having drum brakes in the rear may have a slight
advantage, in a car. But using a single technology has advantages to,
so switching to disc brakes does make sense.

New bicycle disc and sidepull and
cantilever brakes work better than the much, much older
centerpull and sidepull brakes on bicycles from long, long
ago. But it ain't night and day, life or death different.


Indeed. There is far too much fear mongering around bicycles, much of it
driven by ignorance and hype.

Well, I used clips initially on the Peugeot, but without the strap,

https://en.wikipedia.org/wiki/Bicycle_pedal#Quill
then bought Shimano M232 in 1995 and PD-M525 in '96.



I changed the brake calipers on my winter bike from
cantilever to V-brakes (also changed the brake levers)
because I found a HUGE difference when trying to stop in wet
snow and/or slush. The V-brakes would stop almost instantly
where the cantilever brakes would maybe slow the bike down a
bit at first. Those cantilever brakes were properly set up
too.


I switched from hydraulic cantilever brakes (Magura) to a cheap V-brake
on the bicycle used during winter for my commute, starting in '96, after
the Magura got stuck now and then on one side. Didn't have any problems
afterwards. Disc brakes may that good now, but they certainly weren't
then, so this wasn't an option.


I think another big advantage with disc brakes besides
their stopping power when wet or snow, is that the wheel
does not have to be perfectly true in order to prevent brake
rub. I think that's a big part of why they're so popular on
MTBs.


Perhaps. But I don't own or ride a MTB, I don't even ride on anything
that isn't paved with asphalt. On the other hand, I heared people
taling about having damaged their disks on long descents. A disk has
less heat capacity compared to a rim. Actually, disc brakes allow much
less clearance between disc and pads than rim brake - that's the very
reason for those differences, a larger ratio. So a slightly deformed
disc is already unuseable, because it gets stuck, where a rim is not.

I certainly watch the disc brake space, but IMHO there is much hype,
partially from users and about use cases different from mine. So I
remain slightly sceptical.

In the 1960's and 70's, my fathers lingerie factory in Smog Angeles
was near a factory that did "computerized" embroidery. The Swiss
computer was in 7ft tall, 19" relay rack. Programming and storage was
on rather large punched cards, very similar to the original 1800's
Jacquard loom except that it used needles:
https://www.google.com/search?tbm=isch&q=jacquard+punched+cards
https://en.wikipedia.org/wiki/Jacquard_machine
Basically, it was an automated version of the needle embroidery paper
template.
"Punching a 12 stitch repeat card on a 24 stitch repeat punch card"
https://www.youtube.com/watch?v=JnwaKaMXSJA
In other words, for 200 years, the improvements in mechanized
embroidery were small evolutionary improvements and refinements of
existing technology.

During the 1980's, computers arrived and changed everything. While
the older mechanical computerized machines operated at the speed of a
mechanical ratchet, the computerized servo and stepper motor driven
machine could go much faster. Suddenly, there was a reason to improve
the underlying mechanical technology. For example, the switch from
one needle, to over a hundred needles. (The most I've seen were was
about 100 at a trade show about 20 years ago). For example, 15
needles and 2 heads:
https://www.toolots.com/double-head-15-needles-embroidery-machine-with-pattern-design-system.html
Notice that the above machine is controlled by a small tablet
computah. Controlling such a machine with punched cards would have
been impossible.

It's much like the transition from steel frames, to aluminum frames,
and now to carbon fiber. The requirements of each material
established the limits of what could be done. For example, when
aluminum tubing arrived, frame makers were building frames almost
exactly the way steel frames had been previously built. With water,
sand, or hydraulic fluid filled tubing benders, they could produce
weird looking frames that resembled a pretzel. Add some shocks and
these became the current standard for mountain bicycles. The odd
geometry is not particularly revolutionary. The method of efficiently
bending tubing is.
