Without Air Or Tubes, In 3D.

Three years ago, "The Retrogrouch" wrote about one of the most interesting and enigmatic companies in the cycling world.

Zeus probably came as close as any bike manufacturer to crafting all of the parts for its bicycles.  Of course, they didn't draw the frame tubes, which were usually Durifort, Vitus or Reynolds.  But they, or one of their subsidiaries did  make all of the other major parts, except for the tires.  But you could still ride Zeus tires on your Zeus bike.  How's that?, you ask.

Well, there was a company in the US called Zeus that made them. But they weren't the kind of rubber someone riding a Reynolds 531 frame with Zeus 2000 components would have wanted.  The appeal of that tire, the Zeus LCM, was found more among novice commuters and folks who didn't want to get their hands dirty or scratch their just-enameled nails. (I can understand that!)

Those tires were airless and didn't go flat because they were solid polyurethane rubber.  I tried them for a half-century and a few days of commuting. I wondered whether I had just experienced what it was like to ride a "boneshaker"!  

As so often happens when a new product comes to market, people think the idea is new when, of course, it isn't.  And when it disappears, it will probably return and have another generation of consumers believing they've just witnessed the most wondrous innovation.

Well, it turns out that the airless tire has been revived during the past few years.  Three and a half years ago, The Retrogrouch wrote about a new crop of such rim coverings. They were not solid, like the Zeus, but like other offerings that preceded them, they had solid inner tube-like inserts.  

Now a German startup company, ProFLEX, has created its own version.  This one does not have an insert but, unlike the Zeus, it is not solid rubber.  Instead, it is supported by a complex honeycomb-like structure inspired by a car tire Michelin introduced last year.  That network mimics alveolar structures like the air sacs of lungs:  solid on the inside and more flexible on the outside.  

(Or, since we're talking about Michelin here, we could say it's the inverse of a baguette, which is crunchy on the outside and chewy on the inside.)

The ProFLEX has one more thing in common with the Michelin tire:  It is 3D printed.

Although I am not sure I would switch over to such tires, I would be curious to try them. I wonder whether their ride is more akin to that of pneumatic tires (most likely heavy ones) or solid tires like Zeus.

None of these airless tires, by the way, should be confused with tubeless tires, which are filled with air and can therefore be flatted.  I know:  Bill and I stopped to help a fellow who'd just been sidelined with his tubeless tires.  

A Ride Of Silence To Speak For Him

In Greek tragedies, the hero falls to a combination of circumstances and his or her personal failings or shortcomings.

One of the reasons such stories endure is that they make the world make some kind of sense.  The combination of situation and personal flaw give a sense of symmetry, if not justice, to the demise of the hero.

Of course, it doesn't always work out that way in life.  Sometimes a person meets his or her fate due to an incident that he or she did not bring on and cannot control.

Such is the story of Roger Grooters, who went on a ride to help people whose lives were changed for the worse by a circumstance not of their making.  

Eight years ago, the Deepwater Horizon Oil Spill (better known as the BP Oil Spill) spewed seemingly endless streams of crude oil into the Gulf of Mexico, befouling beaches in five US states and Mexico and leaving birds, fish and marine mammals sick, helpless or even dead.  Grooters wanted to help the people from whom the spill their property, livelihoods and health.  

His pastor and fellow church congregants told him there was nothing tangible he could do.  He thought otherwise.  So, on 10 September of that year, he got on his bicycle in Oceanside, California, near San Diego, with the intention of reaching Jacksonville, Florida.  He documented his trip, which raised $12,000, on a blog called Roger X Country.

The name of that blog has been changed to We Ride For Roger.  A little more than a month after he started his ride, a pickup truck was barreling down State Road 20 just outside of Panama City, in the Florida Panhandle.  The driver was texting and--unfortunately, you can guess what happened next:  He plowed right into the back of Grooters.

You can probably guess what happened next:  He didn't make it to Jacksonville.  He didn't make it, period.  His ride ended after 2179.4 miles, or about 300 miles short of his destination.

The following year, a group of cyclists that included some of his family members gathered at the crash site and continued his ride to Jacksonville.  He rode to raise awareness of the victims of one disaster; they were riding to raise awareness of the victims of the kinds of disasters that occur all too frequently on roadways in Florida and elsewhere.

The Ride Of Silence

A cyclist has a greater chance of being killed by a motorist in the Florida than in any other state in the Union.  I am sure that at least some of the 100 riders who gathered yesterday at Pensacola State College were aware of that. They participated in a seven-mile "Ride of Silence" along the city's streets in drizzle and rain.  At the beginning of the ride, organizers read the names of dozens of cyclists who have been killed while riding in the Florida Panhandle as bagpipers played "Amazing Grace".

The riders wore armbands--black for those who'd never been struck by a car, red for those who had.  I couldn't find a count, but from the photos I saw, the red bands were numerous.

Oh, by the way....The driver was so immersed in his texting that he didn't realize what he'd hit until the police stopped him.  He was cited and fined but never apologized to Roger Grooters' family.

A Ride Through History And Culture

If you've been following this blog, you know that I sometimes, oh, digress a bit into subjects like culture, history, politics, the arts and literature.  

Now the Museum of Ventura County in California has opened what, from the description I read, sounds like what this blog would be if it were an exhibit.

"Pedal Pushers!  Bicycling in Ventura County" is running until 17 June.  It will, among other things, contrast utilitarian bikes of the late 19th Century with sleek modern racing bikes--and highlight all sorts of machines in between.  In addition to bikes, the exhibit will include catalogues, photographs and various kinds of art work related to bicycles.

The purpose of the exhibit, says Charles Johnson, is to show the evolution of the craft and art of bicycle-making and to demonstrate the ways in which bicycles are a reflection of their times.  "We realize what the bicycle has meant in culture over time, and it has meant different things to different people," explains the Museum's research library director.

One of the best illustrations, if you will, of what he means is one of his favorite photographs.  It shows members of the Ventura Bicycle Club assembled on Ventura's Main Street in 1898.  Club members are dressed in their "Sunday best."  Johnson finds that, and the fact that there are so many women in the photo, interesting.  It shows that "bicycling was not an Everyman's sport at the time," he elaborates.  "Bicycles were like $20 and up to $100.  This is not a working man's salary in 1898.  You had to be very wealthy."

That photo would make an interesting contrast with another in the exhibit.  It was taken a century later, in 1998, and shows the California State Championship cyclists zipping past Ventura's City Hall.

If I were in the neighborhood (which,to Californians, means anything within a two-hour drive), I would definitely go to that exhibit.

What Kind Of Clouds?

Is it fog?  Or is it smoke?

When it swirls around the arches of a bridge, I think most people would say it's fog.

But when it's at the Gate of Hell--or Hell Gate--it seems more like smoke.

But what about when it drifts over the city

or clouds the view of the prison?

Whatever you call it, I have pedaled through fog and smoke on my way to work.

It Was Always The Future--Until Now?

A sportswriter once joked that soccer (what the rest of the world calls football) will always be the sport of the future in America.

And an economist once said, only half in-jest, that Brazil will always be the country of the future.

Likewise, back in the '70's Bike Boom, bicycles were being touted as the "transportation of the future."  Around 1979 (the time of the second American "gas crisis") I saw, in a shop window, a touring bike with a sign hanging from it proclaiming it "the RV (recreational vehicle) of the '80's."

Then, of course, Ronald Reagan was elected and put the kibosh on anything--except nuclear power--that might've reduced this country's dependence on fossil fuels.

Through the '80's and '90's, bicycle sales in the US basically flatlined, with a few upticks in the middle of each decade.  Anecdotally, I don't recall seeing many more cyclists on the road in the late '90's than I saw around 1983, when I first moved back to New York.  When I was mountain biking in the mid- and late '90's, I would sometimes see new faces on the trails, but they never seemed to do any other kind of cycling.  I wonder how many of them still ride.

I got to thinking about these phenomena after I came across Clive Thompson's article in Wired. "The Vehicle of the Future Has Two Wheels, Handlebars and is a Bike," exclaims the title.   I checked my cynicism at the door and read it.  He made one really interesting point:  The same technologies that are bringing us driverless cars and other things that seemed like the stuff of science fiction not so long ago are bringing us back to a reliable technology that's more than a century old, i.e., the bicycle.

One of the main drivers, if you will, of that would-be trend is bike-sharing programs.  As he pointed out, they were tried way back in the '60's but, with no way to track the location of the bikes, the programs quickly died.  When the first of the modern share programs started just over a decade ago, the technology that gave rise to "smart" phones and their apps made it possible to track bikes--and, in the early programs, to create docks where bicycles could be secured.  Newer programs are, of course, dockless because they rely on another technology--phone apps.

Thompson didn't intend any pun when he said that to see the future, we don't have to re-invent the wheel.  And I don't mean a pun when I say that perhaps technology is bringing us full circle.

Bicycles just might be the transportation of the future--right now.
