Lighting--And Measuring--The Way

Soubitez and Huret.

What do they have in common?  Well, for one thing, they're both French.  For another, they made parts and accessories found on constructeur bikes as well as basic ten-speeds from the 1970s Bike Boom.

Huret was best-known for its derailleurs, though it made other parts.  Soubitez, on the other hand, was renowned for its bicycle lights, most of which were dynamo-powered.

So, other than being French and found on many of the same bikes, Soubitez and Huret wouldn't seem to have much in common--or much reason to collaborate.  Or would they?

In addition to derailleurs, shifters and frame fittings (such as dropouts), Huret also made some cycling accessories.  Perhaps its most famous was its Multito cyclometer, which ran quieter and registered more accurately than other bicycle odometers because it used belt-driven pulleys rather than the wheel-and-striker system of more traditional devices like the Lucas. 

Before the Multito was introduced, in the late 1970s, Huret made speedometer/odometers that attached to the handlebars and emulated similar devices found on motorcycles and in cars.  Huret sold it under its own marque, but bike makers like Schwinn rebranded it, which is how it ended up on countless kids' "muscle" bikes of that time.

Schwinn and other companies also rebadged Soubitez lights and dynamos, including the extremely popular "bloc" dynamo-light combo that attached to the front fork. (I had one on my Continental.) 

Even with the seeming ubiquity of Soubitez lights and Huret speedometers and odometers, I don't think it ever occurred to me (or anyone I knew) to combine a light with a speedometer or odometer.  Apparently, though, it was done.  

I tried to find more information about the Soubitez 941 K N.  It may well have been exported to the US and I missed it, but I don't recall seeing it anywhere back when so many of us rode with Soubitez blocs and Huret speedometers (and derailleurs:  the one on my Continental was a re-branded Huret Allvit).  The 941 K N seems to have been supplied with a Huret speedometer cable and driver.  They may well have been the power source for the light.  Or, judging by the shape of the light, it may have housed dry-cell batteries.

If that driver and cable were indeed the light's power source, it's not hard to imagine that the Soubitez 941  K N may well have influenced modern bike computers. Otherwise, it's an interesting curiosity.

A Time Capsule In A Local Bike Shop

In this blog, I have often mentioned Bicycle Habitat.  It's a fine shop (well, now they're a series of shops) and I have a relationship with them that goes back decades, to the time I was working for American Youth Hostels and Habitat was around the corner.  They've remained a "go-to" source for me, and their chief mechanic and partner, Hal Ruzal, turned me on to Mercians.

I also patronize a shop in my neighborhood:  Tony's, right in the heart of the still-Greek part of Astoria.  Actually, I learned about them years ago, when I was an artist-in-residence at St. Mary's Hospital for Children and a chain snapped on my way home.

Recently, I bought a couple of things from them.  I got to talking with the owner, who is friendly and helpful.  Although he sells current-model Cannondales and Treks, he has a trove of older parts.  He probably wasn't joking when he said some of them have been there since the shop opened in the early '70's.

I spotted one such piece of equipment in his showcase:  a pair of Shimano bar-end shifters from the '70's.  "I haven't seen those in a while," I remarked.

"I can show you something else you probably haven't seen in a long time."

That was an understatement, to say the least.

I think that I've seen one other set of Simplex bar-end shifters in my life.  Certainly, I haven't seen them in four decades, or close to it.  

Most cyclists who rode bar-end shifters during the '70's and '80's chose SunTour's.  I even saw a few otherwise all-Campagnolo bikes with "Bar Cons," and with good reason:  Sun Tour's ratcheting mechanism made them much smoother and more reliable than other companies' bar-end shifters.  To this day, they are probably still the best-selling bar end shifter of all time:  Many cyclists, even some who aren't "retro-grouches," seek them out on eBay and other places.

If my own observations are indicative of wider trends, I'd say that just about everybody who didn't use SunTour's bar end shifters in those days opted for Shimano which, while not as pleasant to use as SunTour's, were still better than the ones made by other companies--including Campagnolo.

Simplex and Huret bar ends (which are often believed to have been made in the same factory) relied on friction to keep the lever in place when it wasn't being shifted.  So did Campagnolo's bar ends, as well as most other shift levers made for derailleurs.  Friction is fine on downtube shifters, but makes for balkier shifting with the extra cable length required by bar-end shifters.

Simplex, however, seemed to believe it had a solution to the problem with its demultiplicateur.  It clamps to the down tube, near the bottom bracket--in the same spot a cable guide would have been placed.  While most guides for rear derailleur cables were (and are) "tunnels" through which one cable runs continuously, the demultiplicateur was a bell crank-like device to which two lengths of cable--one forward to the shift levers, the other rearward to the derailleur--were attached to pivot points with differing radii.   This increased the mechanical advantage, which made for easier and smoother (if not necessarily more accurate) shifts.  A few constructeurs and custom builders brazed them onto their frames, most often tandems, which required cables longer than some of the rides people take.

Based on my limited experience with the demultiplicateur,  I'd say it did what it was intended to do, and did it well. It made shifting those old Simplex and Huret derailleurs (as well as Campy derailleurs that didn't have "Record" or "Gran Sport" in their names) tolerable, even with bar-end shifters.  But shops usually tried to dissuade customers from them:  For one thing, they were never easy to come by.  But, more important (at least from their point of view), they were more complicated than other cable-routing systems, which meant that mechanics hated installing them and customers balked at the extra cost (for the extra time needed) to install them.

I was tempted to make an offer on those shifters and their demultipilicateur, which were still in the packaging from nearly half a century ago.  But I encouraged Tony to list them, unless he wanted to keep them:  Someone out there is restoring a French bike and would want, if not the shifters, then at least the demultiplicateur.  Or, I'm sure, some collector would want them.

I asked Tony whether he had any Simplex downtube shifters.  (Of course, I'm thinking of the retrofriction levers.)  He doesn't think he has any, or any other vintage downtube levers, he said.  But those Simplex bar-ends were certainly a find!  Even if you're not interested in vintage bike equipment, people like Tony are fun and interesting to talk with just because they've been involved with bikes for so long. Oh, and I shared my reminisces about Greece with him.  He assured me that my itinerary was a good one for a first visit!

A Honeycomb Or A Spider? From Huret?

When I first became passionate about cycling, the best frames--usually made from Reynolds 531 or Columbus SL tubing--featured intricately-cut lugs, like the ones made by Nervex:

Nervex lugs with extra-long tangs on a 1950 Mercian Vincitore

A good production frame like the Peugeot PX-10 would use Nervex lugs "as is"; custom frame builders might file them to even finer points, or make a cutout "window".  

A few builders even cut plain lugs into their own distinctive patterns. The British builders in particular were noted for their distinctive scrolls, trellises and other shapes and patterns.

During the mid to late 1970s, however, bicycle makers--even the small-production custom builders--shifted to plainer "spearpoint" lugs.  Sometimes those artisans filed them to elongate the "spear" or, as they did with Nervex lugs, cut a "window" in a particular shape, such as a heart, diamond or cloverleaf, into the body of the lug.

For all of the fancy lugwork, though, dropouts looked more or less the same.  Again, some custom or low-production builders filed them or did other finishing work to make their bikes all the more distinctive.  Still, because most high-quality dropouts looked so similar, there wasn't as much a builder could do to make that part of the bike stand out.

One notable exception this:

Is it a honeycomb?  Or a spiderweb?  Did Huret make it?

In 1974 and 1975, Gitane "Interclub" and "Tour de France" were made with this dropout.  A few other bikes--all of them French--also featured this unique frame fitting.  

Often called the "honeycomb" or "spiderweb" dropout, its provenance is somewhat mysterious.  It's usually referred to as a "Huret" dropout because the bikes that came with it always seemed to have Huret derailleurs attached to them. (Yes, even on Gitanes, which were notorious for coming with parts that were very different from the ones listed on catalogue spec tables!)  I could not, however, find this dropout in any Huret catalogue or brochure from 1974 or 1975--or, in fact, from 1969 through 1981.

From what I've gathered, it seems to be of good quality.  One discussion board says that it was cast, rather than forged as Huret's (as well as Campagnolo's) road dropouts were.  However it was made, the "honeycomb" or "spiderweb" seems to be robust, as no one seems to know of any that broke or otherwise failed.

Apart from its appearance, the "'comb" or "'web" had one other interesting--and useful--feature: without modification, it could accept Campagnolo, SunTour, Shimano and Simplex as well as Huret derailleurs.  This is particularly serendipitious for anyone who wants to outfit an Interclub or Tour de France frame with modern components.

Huret dropout

Nearly all dropouts made since the 1980s are patterned after Campagnolo, which has a 10mm threaded mounting hole and a "stop" on the underside, at the 7 o'clock position.  (SunTour and Shimano dropouts from the 1970s and 1980s were also made this way.)  A Huret dropout also has a 10mm threaded hole, but its "stop" is at the four o'clock position. 

Campagnolo dropout. Note the 'stop' at the 7 o'clock position, as opposed to the 4 o'clock position on the Huret.

What all of that means is that a Campagnolo derailleur will fit into a Huret dropout, but it might mount at a strange angle, which could impede its shifting.  A SunTour derailleur doesn't share this problem, as its angle-adjusting screw has a lot of range.  In fact, Schwinn Superiors from 1976 through 1979 came with SunTour derailleurs mounted on Huret dropouts.  So did some Motobecanes from that period.

On the other hand, some Huret derailleurs won't work on Campy dropouts at all.  Two different versions of the Jubilee were made:  one for Huret's own dropouts, the other for Campagnolo.  Other Huret models, like early versions of the Success and Duopar, would work with adapters Huret offered; later versions of those derailleurs were made only to fit Campagnolo-style dropouts, which had become the de facto standard.

Simplex dropout

Simplex dropouts, as opposed to the others, had a 9 millimeter unthreaded hole and no "stop".  If you want to use any other derailleur, you have to tap out the hole and grind a "stop":  a rather delicate procedure, especially if the dropout was chromed, as it was on many bikes.  Because SImplex derailleurs attached to the dropout with a recessed allen bolt that threaded into the derailleur's top pivot (in contrast to other derailleurs with top pivot bolts that threaded directly into the dropout), it could be used in a Campy dropout--with a "Class B" fit.

So...If you have a bike with the "honeycomb" or "spiderweb" dropouts, you have no reason to fear, at least according to everything I've read.  But, honestly, you know you like it for its looks, or at least its uniqueness.  They don't make them like that anymore!

What If Sanko Ruled The World?

Most of us who came of age around the time of the '70's Bike Boom believed that in the beginning, good bikes and components came from England, France, Italy and a few other European countries.  Reliable but heavy and clunky bikes were made in the US; Japanese manufacturers copied what Europeans and, sometimes, Americans did.  And, until the time of the Bike Boom, the Japanese stuff was of lesser quality.  Some of us still believed that narrative long after reality proved otherwise.

Thus, we thought that if you were a racer, super-high mileage rider or simply wanted to ride without being weighed down by your wallet, you equipped your bike with Campagnolo components, especially the Nuovo Record rear derailleur.  In our heart of hearts, we knew that SunTour derailleurs shifted better.  But if a Campy costs four times as much, it must be better, right.

So, while racers and other active riders--or rich blowhards--opted for Campagnolo, in-the-know cyclotourists, recreational riders and other types of cyclists soon learned that, whatever their gearing needs, a SunTour VGT (or, later, Cyclone) was their best bet.  Eventually, racers and those with pretentions toward being racers would realize that SunTour derailleurs--and, by extension, other top-flight Japanese components--had "caught up" with or, in some cases surpassed, their European counterparts.

The funny thing is that none of us knew that more than a decade earlier, a Japanese manufacturer made a derailleur that far surpassed anything else that was made at the time.  Legend has it that so much was spent to reseach, develop and make this derailleur that it bankrupted the company.

Just a year after Nabuo Ozaki designed the single most influential derailleur in the history of cycling--the Sun Tour Gran-Prix--a smaller Japanese company came up with a "best of" derailleur that incorporated the best design features--except for SunTour's slant parallelogram--of other derailleurs.  To be fair, whoever designed the derailleur I'm about to mention may not have known about SunTour's design, as it may not have gone into production and in those pre-Internet days, such information would not have traveled as freely or quickly.  Also, I think that even had this derailleur's designer known about SunTour, he wouldn't have incorporated its design as it was so new and radical.  He probably would have thought it best to copy, as closely as possible, European designs, as most Japanese bike and component manufacturers did at the time.

The derailleur in question was, apparently, produced for only one or two years and was never exported, at least not in any significant quantities.  Thus, to this day it remains all but unknown to cyclists outside of Japan. Even within Japan, not many were sold, as it was more expensive than the Campagnolo Record or any other derailleur.  Because of its rarity and quality, it is one of the most sought-after components by Japanese collectors, who tend to favor vintage French (and sometimes British) stuff.

• 
  

The derailleur I have been talking about is the Sankyo Procyon PV-III.  I have never seen one in person, but what I've seen in photos of it leads me to think that it was indeed of the extraordinary quality attributed to it.  The knuckles and parallelogram plates were made of nicely-finished aluminum.  Recall that at that time (1965-66), Campagnolo's top-of-the-line derailleur, the Record, was still made of chrome-plated bronze.  

The Procycon had two sprung pivots, as Simplex derailleurs had. (Only the lower pivot on the Campagnolo Record was sprung.)  This allowed, in the absence of a slant parallelogram, for the chain to ride closer to the cogs than it would with a Record.  Also aiding the shift was a clever mechanism that kept the cable stop and cable clamp in alignment, and a pulley cage with an offset pivot.

And the build quality, from what I've read and heard, has never been surpassed, not even by Campagnolo's or Mavic's derailleurs.  While SunTour derailleurs had an overall better design, they didn't have the otherworldliness, or perception thereof, that the Procyon had.  

Now here's something to consider:  What if the Procyon, rather than the Campagnolo Nuovo Record, had become the derailleur of choice in worldwide pelotons?  Would SunTour have become as influential as it did?  If SunTour derailleurs had less influence, would Shimano have copied their most salient design feature and created a successful indexed shifting system?  And what would, or wouldn't, other derailleur makers like Huret and Simplex have done?

My First Piece Of Jewelry: The Huret Jubilee Derailleur

When you get to be my age, you realize that had you saved the stuff you wore in your youth, you could sell it today as "vintage."  It seems that some people are trying to do the same thing with bike parts.  I find myself shouting things they don't teach you in French 101 whenever a Craigslist or eBay listing refers to a Simplex Prestige derailleur as "rare" or "vintage."

Whenever I see that testament to French plastic technology--or the Campagnolo Gran Turismo with its scimitar-like cage or the Huret Luxe Super Touring, which looked like a disjointed crane's neck made from steel plates--I think, "They don't make them like that anymore--Thank God!"  If those things are "vintage", I'm all for the present and the future

But there are a few no-longer-made components that can be called "vintage" without making me wince.  Such parts are, of course, sought out by collectors or even still used on everyday riders.  Such parts were not only "good for their time" but still are valid today because they have some feature or another that today's stuff lacks.

Sometimes that factor is aesthetic.  Let's face it:  Most bikes and parts from the past look better than almost anything made by anyone besides a custom builder or small-scale manufacturer today.  I admit that there are some things I own and ride for that reason alone.  But some of those same bikes and parts--and others--are designed in ways that are more practical or versatile, or simply "made better", than what you can buy today.

And, believe it or not, some old parts are actually lighter. A case in point is the Huret Jubilee rear derailleur.

I actually owned and rode two--a short-cage and a long-cage version-- for a number of years.  I raced, toured and even did some "rough stuff" on them.  And I even took a tumble or two on them.

My short-cage Jubilee adorned my Cannondale racing bike for a few months.  Then it graced my Colnago Arabesque--on which I raced and trained and did a number of long rides--for another half-dozen years.  I rode the long-cage version for a couple of years on a Bianchi that I turned into a light tourer, then on my Miyata 912.

On all of those bikes I shifted the Jubilee with what is, to my mind, the best non-indexed lever ever made: the Simplex retrofriction.  And I had the "teardrop" version--to my eye, the prettiest shift lever in history--on the Cannondale and Colnago. 

With those levers, the Jubilee shifted quite well, especially given the standards of the time.  It wasn't quite as easy or accurate as the SunTour Cyclone (or, for that matter, anything in SunTour's "V" series).  But I actually preferred the Jubilee to any other manufacturer's (besides SunTour's) top-of-the-line derailleur.  For one thing, it shifted as well--or, at least, not noticeably worse than--the Campagnolo Record series, Simplex LJ or Shimano Crane.  To be more precise, the Jubilee shifted about as quickly and perhaps a bit more accurately, and definitely more smoothly, than any of those mechanisms.

I bought my first (short-cage) Jubilee from Frank Chrinko, the proprietor of Highland Park Cyclery, where I worked for a time.  He thought well of them (and used the Success, Huret's other high-end derailleur) and said he hadn't noticed any problems among the (admittedly few) customers who used them.  On the other hand, I heard horror stories about how if you looked at it the wrong way, it would explode into a million little pieces.  Such fears, I found, were greatly exaggerated: Both of my Jubilees survived falls and continued to work as well as they had been working.

I think that Jubilees lasted longer than many people expected precisely because they were so minimalist:  There weren't as many ways it could be struck or snagged.  That is the reason why, interestingly, a few early mountain bikers and some cyclo-cross riders used it.

The Jubilee also holds the distinction of being one of the few rear derailleurs that was completely disassemblable for cleaning and maintenance.  Huret actually offered spare parts, though they weren't easy to find (at least in the US).  I'll admit that, once disassembled, it wasn't the easiest thing to put back together, especially if you didn't have a diagram (which was even harder to find than the spare parts).  

So how did the Jubilee get its name?  Huret was founded in 1920 and in 1970 decided to celebrate by creating the lightest derailleur ever made.  They succeeded--the short-cage version weighed only 140 grams (the long-cage version weighed 157).  Ironically, the later "drillium" version was five grams heavier!

The Jubilee was first introduced in 1972 (the same year as the Simplex Super LJ and SunTour VGT) and found its way to the US a couple of years later.  The Motobecane Grand Jubile came equipped with it and other high-quality French components; so did the Raleigh Competition.  In 1974-5, Raleigh's two-steps-up-from-entry-level Super Course, with a frame that had straight-gauge Reynolds 531 in its main tubes, came with a version of the Jubilee that fitted to the non-forged dropout with a "claw" hanger.  From what I heard in bike shops at the time, Raleigh was trying to offer the lightest bicycle available at its price point (about $175 at the time), and the Jubilee shaved those few grams that gave the bike its edge over whatever the next-lightest bike was in its price category.

Sachs took over Huret in the early 1980s and continued to produce the Jubilee until the end of the decade.  Later versions bore the Sachs-Huret logo, and later simply "Sachs", in the black-and-gold badge that sported the Huret name in the familiar cursive lettering for so long.

Late in the 1980s, Sachs (which had also taken over French component makers Maillard and Sedis) became part of SRAM.  It seems that around that time, the Jubilee was discontinued as all of the SRAM-Sachs derailleurs were modeled after the Shimano models with slant paralellogram bodies and two sprung pivots.

Going (Wing) Nuts

These days, when I hear the word "wingnut", I think of Rush Limbaugh, Fred Phelps, Jerry Falwell and Sean Hannity. 

Now, some of you may have decided to stop reading this post--or my blog--having read that.  But, hey, we have our differences, but we all love cycling, right?

Anyway...I am old enough to remember (There I go again!) when the term "wingnut" actually denoted a specific bicycle part.  And, I actually used a pair on one of my bikes.  You may have used--or still be using--them.

I had a pair that looked something like these on one of my bikes, long ago and far away:

Mine were chromed.  But they were shaped like those and indeed made by Huret in France.  I never saw the bronze version until I went to France.  At first, I thought they were corroded, as it's not unusual to see French people--especially in the countryside--riding bikes as old as they are.  Even if they (I'm talking about the wingnuts now!) were corroded, they would have been lovely.

Actually, I don't think I've seen a bike wingnut (as opposed to a right-wing radio talkshow host) that wasn't lovely.  Maybe it's not possible to make one that isn't attractive.

Of course, with good cheap quick release skewers available, there is little practical reason to use them today.  In my opinion, they should never be used on a rear wheel unless the rider is very light or weak and never rides uphill, into the wind or out-of-saddle.  But, I guess if you have a bike with solid axles and want to make the front wheel easily removable--say, for transport or storage--a pair of wings on the front is a good, and less expensive alternative, to replacing your axle or wheel.

And, of course, you can give your bike a little more style or enhance a "retro" look.  In addition to the Huret, I particularly like these from GB:

and from Gripfast:

I would trust the Gripfast ones because I've used their track nuts, which are solidly made and lushly chromed.  I never had any problems with my Hurets.

If you prefer something more modern, check out the ones from Velo Orange:

They're almost Bauhausian, at least to the extent that a wingnut can be Bauhausian.  Plus, they're made of stainless steel.  The only reservation I'd have about installing GBs on a bike I'd actually ride (as opposed to one that would hang on a wall) is that old alloy can be brittle.  That's a reservation I'd have about almost any old alloy component; it's not a commentary on the item's quality, as GB was making good stuff during the time those nuts were manufactured (1940's-1960's).

Here are some more examples of vintage wingnuts.  Have a good time looking for them on eBay!

 

Old Glory, The Union Jack Or Le Bleu, Blanc Et Rouge

Three years ago, I wrote about red, white and blue bicycles--and someone who had a red, a white and a blue Cannondale.

Now I'm going to show you some red-white-and-blue (or bleu, blanc et rouge) components and accessories. 

Ironically, one of greatest pieces of Americana kitsch--in bicycle components, anyway--was made in France:

When SRAM took over Sachs--which, in turn, had swallowed up some French component manufacturers such as Huret, Maillard and Sedis--they continued to manufacture components in the old French plants for a few years before moving their production to Taiwan (except for the chains, which are made in Portugal).

In a way, it makes sense that the "Betsy" derailleur appeared when it did , circa 1997.  That's when the craze for mountain bike parts anodized in a rainbow of colors hit its peak.  In some ways, it was a reaction against the gray uniformity (literal as well as metaphorical) of what Shimano was producing at the time.  Yes, their stuff worked fine (except for the early Rapid Fire shifters).  But a bike equipped with them had all the personality of, well, a Gateway computer with Windows 98 (which, I admit, I used for nearly a decade).  

Another offspring of that craze was the Paul Powerglide derailleur:

In addition to the red-white(well, silver)-and-blue combination shown here, it was also available in a "rasta" finish as well as purple, green, blue, red and other standard anodized colors. Whatever you chose--even plain silver or black (Now why would you do that if you were spending $280 on a derailleur?) your derailleur was emblazoned with the stars and stripes.

Here's another tricolore derailleur from around the same time:

Although branded "Stronglight", it was most likely made in the same factory as "Betsy" in the first photo.  Also, once the colors and badges are removed, it's pretty much identical to a Sachs "Success" or "Quartz" from that period.

Now here's a tricolore acessory that gets me misty-eyed:

This Zefal "Competition" pump is the predecessor of the HP series.  In fact, if you take away the thumb-lock valve fitting and the handle that switches between "HP" 9for pumping" and "X" (to mount it on your bike), you have a "Comoetition",

I used a "Competition" for years, on several bikes.  I had a SIlca Impero, which was about 60 grams lighter, for my racing bike, but for every other kind of riding, I used my Competition.  It worked better and was more durable than the Silca, and its color scheme reminded me about "liberte, egalite et fraternite."  Why I wanted to be reminded of those things, I don't know, but I don't think I'm any the worse for being reminded of them.

I'm sure there have been other components and accessories in red, white and blue or bleu, blanc et rouge.  Now all we need are bike parts that play "The Star Spangled Banner" or
 "La Marseillaise" (or, perhaps, "God Save The Queen") when you need a boost of energy.

Happy Fourth Of July.  Wish me a happy birthday.  (Yes, it's today!)

 

It Made Our Bikes Possible

We have all had our life-changing moments, for better and worse: the first kiss, finding out that a hero or role model was merely mortal, tasting an unfamiliar food and liking (or disliking) it more than we expected, or doubting something that had always been believed or assumed.

I'm not going to tell you that I've had such a life-changing moment today, or within the past week or month.  But I got to thinking about those revelations or epiphanies or whatever you want to call them in our cycling lives.

Some of us experience such a moment upon riding a bike with dropped bars or a hard leather saddle and discovering it is actually comfortable--or, at least, not as uncomfortable as we expected.  Or it can come when we try a new genre of riding or type of bike:  For example, I never expected to fall in love with fixed-gear riding.  Conversely, some of us might learn that we do not have the time, resources or talent to become the racers we hoped to be--or that age or other changes in our bodies might mandate changes in the way we ride.

And then there are the seemingly-smaller, but nonetheless influential experiences that cause us to see some aspect of our cycling in a different way.

If you came of age during the 1970's (as a cyclist, anyway), one such experience could have come after you'd spent some time riding a typical bike from that era, which came equipped with Huret or Simplex derailleur--or the Campagnolo Valentino or Gran Turismo. Perhaps the derailleur broke, wore out or rusted solid (a common occurrence with Huret derailleurs in rainy climates).  Or you got to ride a friend's bike, or test-ride one in a shop.

Your friend's bike, or the one you test-rode, might have been equipped with the same derailleur your shop mechanic installed (or recommended, if you did your own work) when your Simplex, Huret or Campy died.  That derailleur was the Sun Tour GT--or, later, the VGT.

Sun Tour V-T Luxe Derailleur, ca. 1974.  From Disraeli Gears

To this day, I don't think I've ever ridden any other bike part that seemed so far superior to its counterparts.  Some people have described feeling that way about using an Apple computer after years of working on machines equipped with Microsoft.  Since I haven't used Apple, I can't vouch for its superiority.  However, I can assure you that the difference between Sun Tour derailleurs and anything else made during the 1970's was at least as great.

From what I understand, Apple is influencing changes in the design of other computers and electronic devices and that, in the near future, I might be using something with their imprint whether or not it's my intention.  

In a similar fashion, even though SunTour went out of business around 1995 (though its name is still licensed for bike parts marketed in Europe and other parts of the world), nearly all of us are riding a SunTour derailleur, if you will.  If you're riding any derailleur that clicks when you shift it, the mechanism will have a geometry very similar to, if not exactly the same as, a SunTour V-series (V, VT, V-GT, Vx, Vx-GT) from the 1970's.  Yes, even arch-rival Shimano adopted it for all but its least expensive rear derailleurs.  

In fact, Shimano's first SIS series of integrated derailleurs, shifters, cogs and chains came out in 1985--the year after SunTour's 1964 patent on the slant-parallelogram derailleur expired.  Shimano had made earlier, unsuccessful attempts at creating an indexed ("click-shift") derailleur system.  Turns out, they needed Sun Tour's slant parallelogram to make it work.

Ironically, when SunTour made its own indexed system a couple of years later, it didn't work as well as Shimano's.  The same was true of Campagnolo's first attempt at such a system:  the Synchro, which some of us called the "Stinkro".  SunTour and Campy both made the same mistake:  They simply retro-fitted an indexed ring to shifters they already made and didn't integrate it with the other parts.   

Campagnolo survived its mistake only because its more traditional Record (the Nuovo, Super and C- series) were still widely used in elite pelotons such as those of le Tour, il Giro and la Vuelta.  As good as SunTour's earlier equipment was, it was still almost unknown in those circles and, costing much less than Campy's stuff, didn't have snob appeal.  

People who started riding during the mid-90's or later have probably never heard of SunTour. But that once-proud derailleur maker made the bikes most of them ride possible--and changed our cycling world.
