When The Sun Was Rising On The Bike Boom

Yesterday I talked about something people younger than "a certain age" probably wouldn't have known:  Cannondale's pre-bikemaking history (1971-1982).

Now I'm going to mention something else us oldsters (some of whom ride roadsters) will remember:  a time when Japanese goods were considered inferior to everything else on the market.  Bike parts, particularly derailleurs, from the Land of the Rising Sun were starting to gain respectability right around the time the 1970s North American Bike Boom was exploding; the bikes would soon follow.

I'm giving you this capsule history because I recently acquired a new-old-stock part from that period.  Although there's nothing exceptional about it, it's interesting and, I believe, good.

I knew I'd had one of an "endangered species" when I saw the packaging:  It looked as if no one had touched it in forty years.  More to the point, it bore signs of an earlier time:

In the days before Shimano came out with its Crane derailleurs and the Dura-Ace gruppo of which it would become a part, nearly all of its parts bore the "wings" "lifting" the "333" logo.  After Dura-Ace and Titlist (the forerunner of 600 and Ultegra) came to market, only Shimano's internally-geared three-speed hubs bore that emblem.  On that basis alone, one could date this hub from 1973 or earlier.

I have tried to show the logo engraved in the hub body and what appears to be a date code:

The letters are "R" and "U".  In every explanation of Shimano's code I've seen, the first letter is the month and the second letter is the year.  The month code goes from "A" to "L", with "A" being January and "L" being December.  The year code starts with "A" in 1976, goes through "Z" (2001) and begins again with "A" in 2002.  

One site suggests that Shimano was using this sequence before 1976 or, at least, that "Y" could be 1974 and "Z", 1975.  If that is the case, the "U" on my hub might mean that it was made in 1970.  But what about the "R"?  Could there have been another code in use for the month?  

Or might those letters mean something else--or nothing at all?

Whatever the case, it's pretty reasonable, I believe, to assume this hub was made before 1973, perhaps even during the late 1960s.  Here's another piece of evidence--which you may have noticed in another photo--that, I believe, supports my hypothesis.

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?

A Steady Chain Of Events In Cycling: From Sedis To SRAM

I'm running SRAM chains on all of my bikes.

That's what I've done for about the past thirty-five years or so.  You might say it's one of my few brand loyalties (along with Mavic rims, Brooks saddles and, yes, Mercian bikes) in cycling.

In a sense, though, my use of SRAM chains isn't a brand loyalty.  You see, when I first started riding with them, SRAM didn't exist.  How's that, you say?

Well, back in the '70's, before Campagnolo, Shimano and SRAM became the main suppliers of quality bicycle components, there were many more independent manufacturers than there are now.  Most of them were relatively small, owned by the families that founded them.  Some, like Brooks and Mavic, survive today, though under the umbrella of larger companies.  However, many--like SunTour and Lyotard, which I mentioned in earlier posts--folded because of mis-steps (SunTour with its indexed shifting system) or simply not updating their products (Lyotard and many other European companies).  Others were bought out by larger companies and saw their venerable names relegated to the tire tracks of history.

One such component-maker was Sedis.  Actually, they made one category of bike parts:  chains.  Nearly all French bikes came with them. They also were common on machines from England and other European countries, as well as Schwinns.  Also, Sedis chains were commonly purchased as replacements, sometimes for chains that hadn't worn out.  I'll explain that in a moment.

Sedis chains were popular mainly for the same reasons as SunTour drive train components and Lyotard pedals:  They worked well and were well-made and reasonably-priced.  Those attributes were most apparent in what might be the most iconic product Sedis ever produced:  the Sedisport chain.

Until Shimano came out with the Uniglide in 1977, nearly all chains had flat side plates.  Shimano designed this chain, with its bulged outer plates, to work with the twisted-tooth sprockets made for their then-new cassette freehubs.  (Until 1985 or so, Shimano also offered thread-on freewheels with twisted-tooth cogs.)  Around the same time, SunTour developed its "Ultra-six" freewheel, which fit six sprockets in the same amount of space as the five rear sprockets that were standard at the time. Sun Tour also marketed a chain, made for them by HKK, with narrower outer plates and pins flush with them. All bike chains up to that time, including the Uniglide, had pins that protruded slightly from the side-plates.

The Uniglide and HKK/SunTour chains shared a problem all Japanese derailleur chains  had in those days:  They stretched and wore very quickly.  And the Uniglide was one of the noisiest chains ever made:  Comparisons were made with Harleys and trucks.

In 1978, Maillard (which would later share Sedis' fate) made its own version of the Ultra-Six freewheel.  The Sedisport was created to work with it.  Originally, the chains were available only in a traditional black finish, but gold and silver versions would become available. 

The Original Sedisport Chain, 1978

The basic black version could be had for about $5-6, the same price as just about any entry-level derailleur chain.  The gold and silver versions were, naturally, a few dollars more.  They were among the greatest bargains in the history of cycle componentry.  

When you took a Sedisport out of its packet (for the black version) or box (gold or silver), it seemed almost floppy, especially to someone accustomed to a Regina Oro chain.  That was a function, not only of its narrower side plates and flush pins, but also of its most revolutionary design features:  slightly flared inner plates (as opposed to the bulged outer plates of the Uniglide) and, most important, its bushing-less pivots.

Those features made the Sedisport both stronger and lighter than any of the other chains I've mentioned.  And, the fact that it had fewer moving parts meant that it didn't need to be cleaned and lubed as often, and didn't jam or develop stiff links.  And, best of all, it shifted even better than any of those other chains--yes, even on SunTour's Ultra-Six or Shimano's Uniglide sprockets.  And on Regina freewheels.

Sedisport with gold finish.

As a result, nearly anybody riding any derailleur-equipped bicycle of anything more than department-store quality had a Sedisport chain.   It's what I rode on my Colnago; I knew other riders who installed it on bikes equipped entirely with Campagnolo Super Record equipment.  Up to that time, the custom was to team up a Regina Oro freewheel and chain with a Record or Super Record gruppo, as Campagnolo did not make freewheels or chains.  But Oros cost about three times as much as Sedisports and didn't last as long or shift as well.  Regina developed its own Ultra Six freewheel (They had a standard six-speed, which was wider than the five-speed) but their quality was slipping.  So, many racers and other performance-oriented riders switched to SunTour Winner freewheels along with Sedisport chains even as they continued to ride with Campagnolo cranks and derailleurs.

Every new model of derailleur chain made since the Sedisport--whether for seven, eight, nine, ten or eleven speeds--has been made without bushings, and with curved or flared inner plates and pins that are flush with the outer plates.  Among those modern chains are today's SRAM chains.

That last fact makes perfect sense when you realize that SRAM chains are Sedis chains.   In the early 1980s, Sedis's bicycle chain division, along with Maillard (which made freewheels, hubs and pedals bearing the Normandy and Atom as well as Maillard brands) and Huret were purchased by Sachs, a German maker of coaster brakes, multigear hubs and components for mopeds and motorbikes.  Through most of the 1980's, the chains were sold under the Sachs/Sedis marque.  Then, in 1996, Sachs became part of the SRAM group.  In the beginning, SRAM components were made in the original French factories that produced Sedis, Maillard and Huret stuff.  But in the early 2000s, most production shifted to Taiwan.  However, SRAM chains have been made in Portugal.  

Through all of these changes, SRAM chains retained the qualities that got me (and so many other people) to ride Sedis chains so many years ago.  I've tried Shimano (as well as other chains) on my Shimano cassettes and Rohloff as well as Wipperman chains on Campy stuff.  SRAM chains always worked better and lasted longer--and were usually less expensive to boot.

Interestingly, the Sedis name survived the buyouts. It currently manufactures chains for industrial purposes in Troyes, where Lancelot was born, if you will.   They first started making chains in 1895, when they were part of Peugeot. (Most people outside the Francophone world don't realize that Peugeot is a large, 200-year-old, industrial company that makes everything from peppermills to trucks.)  At that time, Peugeot manufactured in Isere.  In 1946, the chain division merged with two other chain manufacturers, Societe Verjoux of the Doubs region and Societe des Chains Darbilly in the Seine region.  The name SEDIS is an acronym of SEine, Doubs and ISere.  They continue to use the logo familiar to so many of us.

 

Shifting

These days, shift levers are curved pieces of metal with cylinders at one end.  The shapes vary somewhat, and the ones attached to brake levers (e.g., Campagnolo Ergo and Shimano STI) are longer.  But, for the most part, they don't call attention to themselves. 

Probably the most elegant shifters ever made were the "teardrop" retrofriction levers Simplex made during the 1970's and '80's:

Next in my beauty contest are the Superbe Pro levers SunTour produced during the 1980's"

Some might say they look even better with the gum-rubber hoods SunTour offered for a time:

I'd probably want those hoods if I were going to install the levers on Vera, my British Racing Green Miss Mercian.

Campagnolo Record levers of that era also had a fairly understated design:

unless some bike maker decided to re-fashion them:

Now, some would argue that an Olmo of that era simply wouldn't be an Olmo without those shifters.  I wouldn't disagree, though I've never owned an Olmo.

I've never owned a Schwinn Sting-Ray, either.  That's probably a good thing, considering the shifter that came with it:

I can't help but to wonder whether it has something to do with the decline in birth rates.   Supposedly, the shifter "clicked" or "indexed".  It's hard to imagine how that was accomplished with the derailleur that came with the bike:  a Schwinn-branded ("Schwinn Approved") Huret Allvit.

In a way, though, I can understand why that shifter was used on Sting-Rays:  the bike's designer was invoking the spirit (or something) of "muscle cars" from that time.  I guess some kid could push or pull that lever and imagine himself on the track at Daytona or something.

But there's no such excuse for this lever, which was made for adult bikes:

If you think somebody cannibalized a Simplex "Prestige" derailleur and glued parts of it to the tops of these lever, you'd be right--sort of. After all, these levers were made by Simplex around the same time they were making all-plastic derailleurs.

And then there are these levers that dare not speak their name:

The "333" on the sticker means that Shimano made them, probably during the 1960's or early 1970's.  SunTour's components were sub-branded "888".  How these companies came up with those numerical designations, I don't know.

One way you can tell it's from that period is the red adjuster knobs and trim.  Both Shimano and SunTour--as well as a couple of other less well-known Japanese manufacturers--made derailleurs and other components with red trim or even small parts. That practice seems to have lasted only a few years, and no one seems to know what inspired it.  The "rising sun" of the Japanese flag, perhaps.

I wonder whether it will work with Campagnolo cassettes. ;-)





 

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.

Another Forerunner To A Shimano "Innovation"

For today's post, I'm going to engage in a bit of bike geekery, as I did in yesterday's post.  Fear not:  This will not be a regular feature of Midlife Cycling.  At least, I don't intend it to be.

As I did in yesterday's post, I'm going to write about a long-forgotten component that featured a design used in later, more successful (at least commercially) bike parts.

From the 1920's until the 1970's, many British bikes featured Williams cranks, chanrings and bottom brackets.  That is not surprising when you consider that those parts were, like the bikes, made in England.  

As Steve Griffiths notes in "Classic Lightweights," Williams has been unfairly judged on the basis of its lowest-quality--and, unfortunately, most commonly-used--model, the C34.  It was a cottered steel crankset, and the arms (or spider) onto which the chainrings mounted was swaged (forced).  Willliams also make much nicer models,including some of those thin,elegant cranks you see on British bikes from the 1960's and earlier.  

But their best crankset--and the only cotterless crankset made in any significant quantity in England--was the AB 77. I have seen one of them in my entire life: on a Claud Butler that came into the first shop in which I worked.  

The AB77 was actually quite nice:  the quality of the materials, machining and finish were high.  It had the same chainring design as the TA Cyclotouriste, Stronglight 49D and the Nervar crank that aped them.  That meant the AB77, like those other cranks, could be set up as a road double with a 42 tooth small chainring  or as a triple with a 26-tooth inner ring.  

But the most interesting part of the AB77 was its bottom bracket.  Presaging a trend by two decades, its axle had a splined rather than square end.  In other words, it was a proto-Octalink or ISIS bottom bracket.  

Unfortunately, that bottom bracket was its fatal flaw.  During the period when the AB77 was produced (1962-mid 1970's), only one other crank had such a design.  It was made by Gnutti in Italy and its splines were of a different pattern from Williams', so the two could not be interchanged.  That was especially unfortunate for Williams, because the bottom bracket, which was made by T.D.C. (once a major manufacturer or headsets and freewheels), didn't last very long. 

When Shimano decided to resurrect this long-forgotten idea during the 1990's, it made the splines broader, which was supposed to increase the stiffness as well as the lifespan of the bottom bracket.  However, they, like their TDC/Williams predecessor, wore out quickly.  The problem with the Shimano splined brackets--and the similar, though not interchangeable, ISIS-pattern bottom brackets made by other companies--had narrower axles and smaller bearings than their square-ended counterparts.  Interestingly, Shimano's Octalink and other companies' ISIS bottom brackets had an even shorter run--not much more than half a decade--than the ones from TDC/Williams.  

A few years after Williams ceased production of the AB77, they were taken over by Nicklin,one of their former competitors, which offered only the C34 and a couple of other low-priced models that were fitted to mass-market bikes from Raleigh, Dawes and other manufacturers.  As production of such bikes ended, so did most of the British cycle-component industry, including Nicklin/Williams.  

A Derailleur I Don't Miss

As I've mentioned in earlier posts, I don't do "retro" for the sake of being retro.  I like the ride of high-quality steel frames, and like the look of lugs.  I also like leather saddles and canvas bags, for looks as well as comfort (in the case of saddles) and durability (the bags).  Also, I appreciate the craft that goes into many of those items.

There are some "old-school" parts I really like, too.  As an example, I probably will ride cranks with square-taper bottom bracket axles for as long as they're available. (I went through eight ISIS bottom brackets in the three years I rode a crankset made for them!)   And, I like Lyotard-style platform pedals with toe clips and straps because they don't require the use of special shoes or cleats--and, frankly, they're better-made than most clipless pedals.  (For a time, I was replacing my clipless pedals every year, even if I didn't crash them.)  And, although I've ridden some of the exotic pre-made wheelsets, and owned a couple of pairs, I prefer handbuilt wheels with traditional (not straight-pull) spokes.

On the other hand, I don't understand the fascination with some "old-school" stuff, save for collectors and people who want to do "period" restorations.  

Here is an example of what I mean.  The other day, this derailleur ensemble sold for 170 dollars on eBay.  Granted, it is in New Old Stock (NOS) condition, meaning it had been sitting in some box or drawer for the past forty years.  

While these parts aren't as common as they once were, they haven't exactly disappeared from the planet, either.  The pieces of the ensemble were made by Huret. The shifters and front derailleurs were decent: not as good as Campagnolo's best or almost anything SunTour ever made, but competent enough, especially in their time.  However, there was no excuse for the rear derailleur, even when it came out.

The Huret Luxe Super Touring rear derailleur was scary.  When you rode it, I mean.  It shifted with all of the predictability of Lady Gaga's sartorial choices.  To be fair, the same could be said for most wide-range touring derailleurs of that time (circa 1972) that weren't made by SunTour.  The Campagnolo Gran Turismo didn't shift much better than the Huret.  But at least the Campy GT shared a trait of other Campagnolo derailleurs at that time.  Frank Berto best described that characteristic when he said, of the Nuovo Record, that it would shift poorly forever.  

From VeloBase 

The Luxe's body consisted of spindly stamped steel pieces riveted together.  Even on the "racing" version of the Luxe, which had a shorter pulley cage, the pieces would work themselves apart, destroying even the pretense of shifting ease or precision.  The long-caged version would deteriorate even more quickly because the extra length of cage and chain created even more stress on the fragile body.

For a couple of years, some European bikes (such as the Raleigh Super Course and  Motobecane Mirage) were equipped with this derailleur.  Such bikes were usually "sport" models with a wider range of gears than were typically found on such model.  The Luxe Super Touring may have been the first European derailleur made to shift onto a 32 tooth rear cog.  (The largest most other derailleurs could handle was a 28; racers in those days typically had largest gears of 21 to 24.)  It came out just as SunTour derailleurs were first becoming available outside of Japan; within a couple of years, SunTours would adorn the Super Course, Mirage and many other mid-level European and American bikes.

When it was new, the Luxe ST sold for around twenty dollars; the ensemble in the photo went for about forty.  Within a couple of years of its introduction, SunTour and Shimano derailleurs that shifted much better, and lasted longer, could be had for half as much, at least in the US. (Japanese components were significantly more expensive in Europe.)  Still, it appears that Huret made the Luxe derailleurs until the early 1980's, when Sachs bought Huret and a few other French component makers.

As I said, I can understand someone buying a Luxe or Gran Turismo for a collection or a "period" restoration.  But I would not install them on any bike I intended to ride anywhere besides an "oldies" show.
