Prone To Revival--And Deservedly So, I Think

Shakespeare never had an original idea--for a story, anyway--in his life.  George Orwell took almost everything that makes 1984 worthwhile--including the notions of "thought crimes," "Big Brother" and its mathematical theme--from We, a novel from a little-known Russian writer named Yevgeny Zamyatin.  (Orwell reviewed the book three years before 1984 came out.)  D'Artagnan was not the creation of Alexandre Dumas; rather, Dumas lifted him--and Athos, Porthos and Aramis--from the first volume of Gaeten Courtilz de Sandras' book called The Memoirs of D'Artagnan.

In the book of Ecclesiastes, we find this:  "There is nothing new under the sun."  So it is in the world of literature and the arts.  So it is in science and technology.  And so it is in the world of bicycling.  In the four decades I have been cycling, almost every "new" idea had been done before, sometimes in the very early history of cycling.  As I mentioned in two recent posts, suspension is one such idea.  Another idea is that of building frames of anything besides steel:  During my formative years, carbon, titanium and aluminum frames were not only created; they were available to the general public (for a price, of course).


Then there are those ideas that never really go away but are nonetheless "rediscovered" by a new generation of marketing types (or, sometimes, actual cyclists who haven't been in the sport for very long).  One such concept is that of the recumbent bicycle.



I am not about to dismiss recumbents, as I have never ridden one myself.  I don't doubt that, as their proponents claim, their aerodynamics can make them faster than standard bicycles.  My concerns about them are twofold:  How well and comfortably can a rider use his or her muscles in such a position?  (At my age, the answer to such questions is more meaningful than it was when I was younger!)  And, how visible is a recumbent rider in traffic?

(I'll admit that the second question is the one that has done more to keep me off a recumbent!)

That there were recumbents before Dan Henry and others were touting them doesn't surprise me.  It's also not surprising to note that in the years just after World War I, some cyclists experimented with riding nearly prone.  Marcel Berthet--for whom the Lyotard No. 23 platform pedal was named--was concerned with aerodynamics, as were other racers and designers who flew or worked with aircraft during the war. 

The Challand Recumbent


But it's truly interesting, if not shocking, to see that some two decades earlier, in 1896 a horizontal bicyclette normale was exhibited in Geneva.  The Challand recumbent, named for its inventor, was said to allow easier mounting, improved stability and greater thrust on the pedals. It had just one problem, though:  It weighed about three times as much as its rider!

Berthet and others who revived recumbents after the War used them in record attempts. Charles Mochet designed his own recumbent--dubbed the "Velocar"--and used it to set records for the kilometer, mile and hour.  In the case of the latter, he broke a 20-year-old record by half a kilometer.



His exploits ignited a debate as to whether the "Velocar" was actually a bicycle.  The Union Cycliste Internationale (UCI) answered that question in the negative, and banned recumbents, as well as aerodynamic devices, from racing in 1934.  The UCI then declared all of Mochet's records invalid.



Given all of the controversy about pharmaceutical and mechanical doping, the controversy over recumbents seems almost quaint now.  Recumbents are, I believe, here to stay, just as--unfortunately--doping is.

His Spirit of Innovation Wasn't Suspended

The other day, I wrote about some bicycle suspension systems that were patented nearly a century before Rock Shox or Girvin Flex Stems came bouncing down the trails.

It's not as if the idea of cushioning the ride and rider died with the fin de siecle Bike Boom.  Indeed, some of you rode balloon-tired Schwinn, Columbia, J.C. Higgins or other bikes with a big spring in front of your handlebars.  That spring was attached to a bars that were, in turn, attached to the front fork.  How much that actually absorbed shock, I don't know.  I have long thought that they--like the "banana" seat struts attached to shock absorbers on bikes like the Schwinn "Krates"--were really intended to enable kids' fantasies of riding a "chopper" on the flats of Daytona.





Around the time that boys (and, on occasion, girls) were tearing up and down driveways and cul-de-sacs, one of the few American adults riding at the time was thinking about real, functional suspension for bicycles.  Having been one of the first commercial pilots (for American Airlines), he no doubt saw the value in keeping his bike stable and upright (the real purpose for suspension on cars and motorcycles) in turbulent conditions.

If you've on any kind of organized bike ride for, say, the past half-century, you have heard his name.  More precisely, you have followed his directions.



Yes, there was a real, live Dan Henry behind the "Dan Henry arrows".  While he is best remembered for his system of road symbols, his most interesting contributions to cycling may well be in the ways he made his bikes more comfortable and stable.  



I remember reading about Dan Henry's bicycle in an issue of American Cycling, the magazine that became Bicycling!  As I recall, the bike was a Rene Herse or Alex Singer--or that of some other prestigious French builder.  He made the mechanisms himself from springs and bar stock he obtained in auto-repair shops.  Again, if memory serves, he said that this system allowed him to ride the lightest tubuar tires and rims under nearly all conditions without getting flats or dinging his rims.

(Interestingly, he would later convince Clement to make tubular tires with butyl tubes, which are more durable and retain air longer than the latex tubes commonly found in high-quality tubulars.)

Another part of his "suspension system", if you will, was something he made himself--from a pair of handlebars, a tandem "stoker" stem and some canvas webbing.  




It seems that every decade or so, someone re-invents this saddle.  When I first became a dedicated cyclist (around the time I found that copy of American Bicyclist in the local library), a similar saddle called the "Bummer" was advertised in Bicycling!  I think one of the magazine's editors test-rode it, probably unaware of his perch's provenance.  

Perhaps it's not surprising to know that Dan Henry was also one of the early proponents of recumbent bicycles, and that he designed and rode such a machine.  I guess he was one of the first cyclists to see that high performance and all-day comfort needn't be mutually exclusive--and, as an engineer and pilot, was one of the first modern cyclists to have the background and skills to realize such a vision.

He died nearly four years ago, just short of 99 years old, riding almost to the end.  I wonder what he thought of some of the suspension designs--especially for downhill bikes--that have come along.

Cut From The Same Cloth--Or Hide

A couple of years ago, to a lot of fanfare, Brooks launched its Cambium saddles.  The stated reason was that some cyclists were looking for something that was, shall we say, is moins d'une douleur a l'arriere than their traditional tensioned leather saddles.

(Pardon my French. There, I said it!)

Ironically, Brooks created the Cambium--which is manufactured in Italy--as their tensioned leather saddles are more popular, at least here in the US, than they've been in decades.

The Cambium uses a fabric made of cotton and rubber instead of leather.  If you started cycling, say, about thirty or fewer years ago, you probably have not seen, let alone used, a cloth saddle.  But they've been around, in one form or another, almost from the earliest days of cycling.

One of the most famous examples is the "Bummer", which was inspired by Dan Henry's DIY project:

From American Cycling, July 1966

If you started cycling arond the same time as I did, you probably first heard his name in refrence to "Dan Henry arrows" or, later, "Dan Henry markers".  For decades, it seemed that every organized ride here in the US was marked by painting the symbols he developed onto pavement.

It seems that every other decade, someone makes a version of the Dan Henry saddle.  Late in the '70's Bike Boom, they were marketed as " Bummer" saddles; someone else revived them during the '90's.  Perhaps they'll return, soon, to a bike shop near you.

I've been tempted to try one, but never got around to it.  Maybe if somene rides one and is willing to let me take a few turns on it, I'd be willing. But I really don't want to buy another saddle that I might or might not like.  That said, if I were to try a new saddle, the Dan Henry/Bummer would probably be the one.

Now, if I wanted a cloth saddle purely for aethetic reasons, this is the one I'd get:


This saddle is said to be more or less a replica of one that was fitted to a Dursley-Pederson bicycle of the Edwardian era.  Tim Dawson, the author of the blog Vintage Bicycle, wites, "I  can report that I find it just as uncomfortable as the Dursley-Pedersen saddle."

Perhaps he needs to re-tension it:
