Raleigh Super Tourer: It Didn't Sell In 1974. But Everyone Wanted One In 2014.

A few days ago, I recounted a chance meeting with a fellow named George in Greenwich.  He complimented Arielle, my Mercian Audax, and showed me photos of his very nice Raleigh Competition GS, on which he converted the drop bars to uprights and made a couple of other changes.

George's 1978 Raleigh Competition GS



His "conversion" is nothing unusual these days (except that his is nicer than most):  Lots of people are taking nice (and sometimes not-so-nice) vintage ten-speeds and turning them into city or country bikes, upright tourers or stylish commuters.



In a comment on my post, George said he was trying to replicate a Raleigh Super Tourer.  It's a bike one rarely finds:  I've seen only  four or five of them.  And I don't recall seeing one on eBay, Craigslist or any of the sites that list used and vintage bikes.  (Then again, I check those sites only occasionally.  Really! ;-))

One reason why it's so rare is that not many were made--at least, in comparison to other Raleigh bikes. As best as I can determine, it was made during four model years:  1974 through 1977.  Another reason is that not many Super Tourers were exported to the US, and even fewer sold.  The few American shops that ordered Super Tourers, as often as not, got "stuck" with them for years.  I would suspect that more than one Super Tourer owner came by his or her steed the way George encountered his Competition GS:  A bike shop had it in the back room (or on the showroom floor) a few years after production ceased.

This parallel between George's experience and the possible scenario I have envisioned is not coincidental:  In essence, the Super Tourer and the Competition (the original as well as the GS) were the same bike.  Well, more or less, just about, anyway.  

Raleigh Super Tourer, ten-speed version 1975


Both iterations of the Competition and the Super Tourer had frames constructed of double-butted Reynolds 531 tubing with quality lugs and dropouts.  As a matter of fact, the original competition and the Super Tourer even had the same geometry.

Much of the componentry was the same: mainly high-end French stuff.  The pre-GS Competition had Normandy "Luxe" hubs and Huret Jubliee derailleurs; so did the Super Tourer.  The short-cage Jubilee--which came on both bikes--shared an interesting trait with other European derailleurs of the time:  It could wrap up miles and miles of chain, even though it wasn't made to handle a rear cog larger than 26 or 28 teeth (depending on your dropout's configuration).  Thus, it could handle triple and wide-range double front chainrings. That is one reason it was often used on randonneuses from the constructeurs.

1974 Super Tourer, 5-speed version (saddle not original)


The Specialites TA three-arm crank graced the pre-GS Competition. Interestingly, the first GS version had the three-arm Campagnolo Gran Sport crankset--with a chainguard! 

Now here's where things started to get weird:  The Super Tourer was made in ten- and five-speed versions.  The ten-speed had what seemed to be a triple version of the Stronglight 93 crankset, with a guard (very pretty, actually) where the outer chainring would have been. The five-speed sported a Specialites TA "Criterium" chainset:  essentially, a a Pro-Vis 5 (a.k.a. Cyclotouriste) with one chainring, and a chainguard..  

For some more weirdness, the Competition GS came with Weinmann "Vainqueur" centerpull brakes while the first year's production of the Super Tourer had Weinmann's short-lived "Dynamic" brakes--sidepulls.  In those days, sidepull brakes came only on bikes at the very top and bottom of the price spectrum; almost everything in between came with Weinmann, Mafac, Dia Compe or Universal center-pulls. The high-end sidepulls like Campagnolo's were ridden mostly by racers.  Most cyclists never saw them:  The only sidepulls they saw were the lower-end models found on cheaper bikes. As an example, the Schwinn Continental was equipped with centerpulls, but the Varsity came with sidepulls. 

So, some people assumed the Competition was a "better" bike because it had centerpulls.  Or, if they knew how good the Super Tourer frame was, they wondered what sidepulls were doing on it.  Unfortunately, they had good reason to wonder--about those sidepulls, anyway.   A few years earlier, Altenberger made the "Synchron", an early version of dual-pivot brakes.  Like most of the company's offerings, it was cheap and crudely finished, intended for lower-end bikes.  Weinmann tried to clean it up a bit. The stopping power was OK, at least in the beginning, and with the levers that came with the Super Tourer. But, in time, the pivots worked loose and, as we used to joke, the Dynamic would devolve into a brake with the worst features of centerpulls and sidepulls.

(And you thought Shimano invented dual-pivot brakes in the early 1990s!)

The Super Tourer also suffered because of another notion novice American cyclists developed during the Bike Boom.  It's a notion I admit I had for a long time:  A "serious" bike had dropped handlebars and a narrow saddle--usually leather Brooks or Ideale, though Italian-style plastic-and-foam saddles were starting to make their appearance.  Shift levers were mounted on the down tube, and such a bike didn't have fenders.

You guessed it:  the Super Tourer had fenders.  The ten-speed version had some pretty neat-looking Bluemels Classiques, which were black plastic with a ribbed chrome stripe down the middle, a white mud flap on the front and a white-framed reflector on the rear.  The five-speed sported silver plastic fenders--which, I believe, were also Bluemels Classiques.  

Fenders?  Fenders!  And upright handlebars.  (I think they were North Road, or some similar bend, from GB.)  And...and...stem shifters!!

Oh...and the first year's production of Super Tourers (the ones with the Synchron brakes) came with mattress saddles. Yes, you read that right:  a seat even thicker than one of Dagwood's sandwiches--with springs!  Vertical springs!  Horizontal springs!  And bag loops that looked like they could carry the biggest offerings from Carradice, Karrimor, Chossy and all of the other classic cycle luggage makers, all at once.

In 1975, the Brooks B66 replaced the mattress saddle.  It had springs but at least it was a...Brooks.  Tensioned leather.  But the bike still had those bars.  And fenders!

You simply couldn't show up on a club ride, let alone ride in a pack of wannabe racers, in the mid-1970's with a bike like that unless you were 90 years old and accompanied by your grandparents--even if that bike had a hand-brazed Reynolds 531 frame, Huret Jubilee derailleurs, Stronglight or TA cranks, etc.   You could just as well have shown up in a petticoat or a chain of mail.

I actually prefer this brown finish--with silver "sable" panels and headtube--of the five-speed model to the green on the ten-speed version!


Now, you're thinking that it's very, very ironic that George and other people are turning classic road machines into bikes like the Super Tourer--forty years after you could have bought such a bike, stock, off a showroom floor--or asked a Raleigh dealer to order it for you.  (Vera, my green Mercian mixte, is really just a female version of such a bike--which is what I wanted it to be.)   Perhaps it's even more ironic that there are new bikes that are, at least conceptually, modern versions of the Super Tourer.  (One could argue that some  Rivendell and Velo Orange bikes are, at least to some degree, updated versions of the Super Tourer.)  A lot of people want sprightly but comfortable rides: something that's relatively quick but will allow them to ride the same clothes and shoes they wear to work or to shop, date or simply hang out.  Or, age and other things have caught up with them and they're not as flexible as they used to be--or simply have lost their pretentions to racing.

What if Raleigh were to introduce that bike today?  They wouldn't have to change much, really:  perhaps only the shifters, which would move to the handlebars from the stem, and would be indexed to accommodate contemporary derailleurs and cassettes. (I have always liked the Jubilee, but I don't imagine it would work very well with handlebar shifters or more than seven sprockets in the rear.)  And, of course, the 27" wheels and tires would have to be replaced with 700Cs.  Otherwise, Raleigh could re-introduce the bike "as is", I think.



Finally, if you think it's ironic that people are seeking out bikes like the Super Tourer--or are converting other bikes into versions of the ST--you'll appreciate (or perhaps wince at) this story.  Near my undergraduate university campus, there was a bike shop that seemed to be there for even longer than the university itself.  Its owner was ready to move to Florida, or any place with warmer winters than New Brunswick, New Jersey.  Nobody wanted to buy the shop, mainly because of its location on what was then the town's Skid Row.  So, he had to sell off his inventory, which--you guessed it--included a Sports Tourer he'd stocked several years earlier.

And, yes, he did sell it--after swapping the upright bars for dropped bars, the mattress saddle for a Brooks B17 and the Synchron brakes for Weinmann centerpulls.  And he took off the fenders.  In essence, he turned the Sport Tourer into a Competition.

Still, he took a loss on that bike.  I wonder whether the person who bought it still has it.  Wouldn't it be funny if he or she--or whoever has it now--"converted" it to an upright commuter or tourer?

A Compliment From Someone Who Would Know: George, WIth A Competition GS

Three days, three rides, three bikes.


Arielle

Yes, after riding Vera (my green Mercian mixte) the other day and Tosca (my Mercian fixed gear) yesterday, today I pealled Arielle, my Mercian Audax.

And today I rode, again, to Greenwich CT.  One of the reasons I've been doing that ride is that I'm finding more and more of the East Coast Greenway in the process.  Also, the ride offers different kinds of vistas, terrain and road (and trail) surfaces--actually, quite a bit of variety for the area in which I take the ride and its distance.

Also, the ride calms my inner cynic.  You see, when weather forecasters say the winds are "light and variable", my IC says, "You guys just don't know.  Admit it!"  But, on the ride, the winds (or breezes) can vary because it ranges from urban streetscapes to marshland, low hills and the shores of a large bay and three different rivers.

Plus, today I realized one of the reasons why I ride to Greenwich specifically.  The parks and old houses have their charm, certainly.  But going to the shopping area--lined with designer boutiques and a "thrift" store where I once found a "pre-owned" pair of lavender made-in-France Chanel ballet flats for the modest (ha, ha) sum of $300 (Alas, they wer the wrong size!) also helps me to put my passions and obsessions into a different kind of perspective.  

That's the lesson I learned today from a fellow who, as I was about to mount Arielle for the ride back, remarked on what a "beautiful" bike she is.  (I used the quotations because he used that word.)  "The attention to detail is amazing", he exclaimed.  He liked everything from the paint job, the pinstriping on the lugs (especially the strokes in the "windows" of the lugs) and the Brooks Pro seat, bar tape and the RuthWorks bags.  Plus, he liked the fact that all of the equipment is first-rate--including the Dura Ace derailleurs (the first parts he noticed) and Mavic rims.


Now, I don't mean to boast when I say I get a lot of compliments about Arielle. (In fact, I got another--from a woman pushing a stroller-- on the way home when I stopped for a traffic light in the Bronx, near Parkchester.)  But the fact that this man--George--went into such detail intrigued me.  Which meant, of course, he had a nice bike--whether or vintage or new--with a lugged steel frame.  He pulled up some images of it for me.  If he ever sends them to me, I'll post them.  But for now, I'll post one that's on Old Ten Speed Gallery:


George's 1978 Raleigh Competition GS


George's Raleigh Competition GS is from 1978, the first year it came equipped with Campagnolo Gran Sport parts (and Weinmann Carrera brakes).  Through most of the '70's, the bike came with Huret Jubilee derailleurs and other high-quality French parts.  Now, as you well know, I like the Jubilee and the TA three-arm crankset that was standard equipment for a few years.  But some of the Campy parts--such as the hubs--were a clear improvement.

George says the bike was sitting in the back of a now-defunct shop on Gun Hill Road in the early '80's, when he bought it.  At some point, he changed the three-pin Campy GS crankset for a five-pin Chorus model "because I thought I wanted a 53 T chainring".  Later, he swapped out the dropped bars and stem for a Nitto stem with a longer quill and "riser" bars--which meant, of course, changing the brake levers. He also swapped the Camapagnolo GS quill pedals for MKS touring pedals.   "But I've saved all of the original parts," he reassured me.

Even with all of the changes, I think it's still a very nice-looking bike.  I told him as much.  Part of the reason is that silver finish, which Raleigh offered for the first time in 1978.  That year, the bike was also available in black, as it was through most of the '70's. I think that even after silver became available, more black bikes sold--at least, I've seen more black than silver bikes from the late '70's and early '80's, when the bikes came with Campy GS equipment.  I like the black, but I prefer the silver, which I think is more elegant.

I don't know whether it's my imagination, but the workmanship on those frames--constructed of Reynolds 531 double-butted tubing--seemed to improve when Raleigh switched to Campy GS.  At least, the lugwork and graphics look cleaner.  If I'm not mistaken,  Competition GS bikes from that period were among the last to be made in Raleigh's Carlton facility, where the top-line models (such as the Professional and International) were built by hand.  Carlton bikes have always been more esteemed than the rest of Raleigh's producton, justifiably so, in my opinion.

"Some people think we're crazy to spend as much time and money as we do on our bikes," George mused.  "But look at that car over there"--he pointed to a custom Bentley.  "That's about $800,000 right there.  And for what?  At least we know we're spending on something that will get us somewhere faster, or in more comfort or style, than a cheap bike will."

He had a point.  There were, probably, other cars on that street that cost more than I've made in my entire life.  And I'm sure that some of those people who were sauntering from store to store--and Starbuck's--probably spend money on things, and in ways, I simply can't imagine.

So, George taught me this:  That no matter how much we spend on our bikes, it doesn't come anywhere near what others pay for less practical, less fun--and, to my eyes, less beautiful--things.  That makes me feel better. But it's probably a good thing I didn't come to such a realization when I was younger.

Assuming A Postition: Scott DH And Cinelli Spinaci

Today, the Union Cycliste Internationale (UCI) is one of those organizations almost nobody loves.  There are plenty of good reasons for that:  The organization is often accused of looking the other way when riders are doping--and taking bribes to do so, and threatening lawsuits against those who accuse it of wrongdoing.  It was, essentially, duped (or so it claims) into violating a country's sovereignty.  And the UCI makes and enforces all sorts of rules that defy logic or reason.

However, there was a time--believe it or not--when the UCI actually made rules that made sense.  One of those occasions came in 1997, when it banned aerobar (a.k.a. "tribar") extensions from competition.



Scott DH bar, circa 1988.  Don't you just love that neon yellow? ;-?
 


You have no doubt seen, and possibly ridden, them.  Originally, they were designed and ridden by triathletes.  They caught on with other racers and wannabes after Greg LeMond rode the final time trial stage of the 1989 Tour de France on a bike equipped with Scott DH bars.  He began that day (23 July)'s stage 50 seconds behind race leader Laurent Fignon.  Rarely does any cyclist--barring a crash or mishap to another--make up so much time on a single stage, let alone the final one, which is usually an individual time trial and is, as often as not, ceremonial rather than consequential.

Greg LeMond on his time trial bike--with Scott DH clip-on aero bars--in the 1989 Tour de France.


When it was over, LeMond--whose 1986 Tour victory was the first by an American--left Fignon in second place, 8 seconds behind in the overall classifications.  That was, and remains, the smallest margin of victory by any overall Tour winner. 

Until then, the jury was out on aerobars.  But a lot of cyclists looked at that result--an 8 second lead over a three-week-long race!--and thought that if the aerobars weren't the reason, then maybe, just maybe...

Sales of Scott DHs took off.   The "forward" position mimicked the "tuck" of a downhill skier, which is where the "DH" came from.  (Before they started making aerobars, Scott was a ski-equipment company.)  At that time, a lot of road bikers were taking up mountain biking, some in the form that would later come to be known as "downhill".  That, I believe, accounted for at least some of the popularity of Scott DHs with wannabes.  And, at that time, some cyclists who'd started off as mountain riders were "discovering" road cycling.  And those triathloners who hadn't adopted aerobars up to that time couldn't wait to get them.


The popularity of those bars, naturally, spawned imitators and tweaks.  Some, like Profile, were made by companies that had never before made bike components.  And most of the handlebar manufacturers of that time got in on the action.


Cinelli Spinaci, circa 1990.


One of the best-known of that new breed of bars was the Cinelli Spinaci.  Its forward reach wasn't quite as far as that of the DH.  So, while it wasn't quite as aerodynamic as the DH, it allowed the rider to assume a position more aerodynamic than the normal road-riding position for longer periods of time.   Also, the Spinaci could be set up in a greater variety of positions.  That latter quality also was one of its downfalls.

The ideal position, or at least the one recommended by Cinelli, set the clamps at 45 degrees and the bars parallel to the ground.  But some riders tilted their Spinacis to the "wheel licker" position in the mistaken belief that being in a below-horizontal position made you more aerodynamic.  Others rode them with the bars tilted so that the end were almost in a direct line with the rider's face.  That position was about as aerodynamic as a boulder.

How do I know so much about the Spinaci? All right, I'll make a confession that might cause some of you purists to lose respect for me:  I used it.  I like to think I was young enough to consider it now as a youthful folly.  Although I knew that the bars would wreak havoc with the aesthetics of my Colnago, I rationalized installing the Spinaci because, well, it was Italian--because it was Cinelli, the same brand as the handlebars to which I was clamping it.

I didn't ride them for very long, though.  As I have  mentioned, there was no benefit in tilting them upward or downward.  And even though riding them in the horizontal position was relatively comfortable (especially with the arm rests), I didn't spend much time riding that way.  So, after acquiring them in the spring, I had little trouble selling them in the summer, as they were at the peak of their popularity.

The biggest drawback, though of Spinacis, DHs or any other aerobar lies in using them while riding them in a peloton or any other kind of group or pack.  When you're riding on the extensions, your hands are nowhere near your brake levers.  On traditional road bars, if you're riding in the drops, you can move your hands to the levers relatively quickly, usually enough to avoid a crash or lessen its impact.  The real danger, though, is not just in one rider using it.  As the UCI folk realized, in one of their rare moments of anything resembling clarity or magmamnity, if a hundred riders are using them and one of them goes down, or there is any other emergency, the result could be, essentially, a race that ends by attrition.

Now, having said all of that, I am not trying to dismiss aerobars.  I never cared for the aesthetic, but I can understand why some riders, especially time trialists, would like them.  The UCI, in one of its increasingly-rare instances of clear thinking, realized that there are some situations in which those bars shouldn't be used, and banned them for that reason.

The Flash Hub Is Gone--Or Perhaps It Never Came!

What is this?




No, it's not a vintage Campagnolo Record front hub retrofitted for disc brakes. (Oh, perish the thought!)  Instead, it's something I mentioned in an earlier post:





It's none other than the Cinelli Bivalent.  It may be the only hub in history that was designed to be used either on the front (as shown in the first photo) or the rear. 



The toothed wheel served no purpose on the front. On the rear, however, the gear cluster or cassette fit onto it.  This was supposed to make wheel removal and installation easier.  From what accounts I've heard and read, it seems to have fulfilled that purpose.



Being a Cinelli item, the quality was most likely excellent.  (Some have claimed that Campagnolo made the hubs for Cinelli.) When the system was introduced during the early 1960's, the hub had a three-piece shell, like most hubs of that time.  A few years later, Cinelli started to offer hubs with single-piece alloy shells.

Although it seems that those who tried the Bivalent liked it, the system never caught on.  The reason usually given is that racers didn't want to use it because if they had to replace a rear wheel, a support van or truck probably wouldn't have another on hand, and the threaded hubs (like Campagnolo's) almost everybody--including all racers--used at the time wouldn't work with it. 

(That, by the way, is also one of the reasons why Campagnolo Record (as well as Nuovo and Super Record) dominated the peloton for so long:  Everyone wanted equipment that was compatible with everyone else's.)

As I mentioned in my earlier post, during the ensuing two decades between the introduction of Bivalent and Shimano's Freehub system (the prototype of every cassette hub made today), there were other attempts to make something more convenient, versatile or stronger than the traditional threaded hub and screw-on freewheel--especially since manufacturers were adding more gears to bikes.  

One of those attempts was SunTour's UnitHub of 1969.  Like today's cassette hubs, it combined the gear carrier and hub into one unit.  From what few accounts I could find, it worked well and was sturdy. However, the public wasn't ready for it--just as it wasn't able to receive another SunTour debutante from that year, the Five-Speed Click indexed derailleur system.

A decade later, Maillard introduced their "Helicomatic" hub, featuring a bayonet-style mounting onto which a gear cluster mounted.  The idea was great (better, I believe, than the Freehub system or any of its descendants), but it was poorly-executed and thus prone to breakdowns.  Shimano brought out its Freehub around the same time and, as the saying goes, the rest is history.

But there was, apparently, an attempt to resurrect the idea of the Bivalent.  A company I had never heard of until I encountered it on Michael Sweatman's Disraeligears site made it--or, at least, made plans for it.  No one seems to know for sure whether any of those hubs were actually made.

The company, EGS, was based in France.  It made one of the most elegant or extravagant, depending on your point of view, and certainly most futuristic derailleurs ever created:  the UpCage.   In essence, it was a classic SunTour derailleur with its pulley cage mounted horizontally and a tensioning arm between the body and the pulley cage.  They weren't in production for very long, even though they were much loved by French downhill racers.

EGS UpCage.  From Disraeligears



Apparently, ESG had big plans:  its website--still up even though the company went belly-up in 2000--shows plans for a "Syncro-Shift" twist-grip control that operated both the front and rear derailleurs.  (Whenever I see any form of the word "Syncro" in a bicycle or component's name, I turn and ride as far and fast as I can from it!)  Also on EGS's drawing board were a brake system and something they called the "Flash Hub."

From the EGS website



ESG's website says the Flash Hub was to consist of a two-part hub, a fixed cassette mount and a moveable wheel mount.  The cassete mount unit was made to stay fixed to the frame's rear fork end.  I can't help but to notice their use of the term "fork end", which just may be a matter of translatation. Still, it leads me to wonder whether it would have worked with vertical dropouts.  No matter:  This system, according to ESG, would make it "child's play" to change the rear wheel.

There is no mention that the hub could be used on the front, so I imagine it wouldn't be possible.  To be fair, when Cinelli came out with the Bivalent hub, many frames made for derailleurs still had 110 mm spacing in the rear, as most freewheels still had no more than four gears.  Most road bikes then, as now, had 100mm spacing in the front fork.  So it probably was easier to make a hub that fit both front and rear than it would be to make such a hub now, when rear spacing is typically 130 or 135mm, and could grow if twelve or more gears and disc brakes become standard equipment.

Still, I have to wonder whether those guys at ESG--who, it seems, were downhill racers or had the attendant mentality-- knew about the Bivalent hub. 

N.B.:  Cinelli Bivalent photos were taken by Al Varick and appear on Classic Rendezvous.

The Gear Maker

During the 1970's Bike Boom, millions of Americans bought ten-speed bikes.  Many people rode them only a few times, or once.  Some didn't like the dropped handlebars or small "hard" seats; others couldn't quite get the hang of shifting derailleurs.  Given the fragile nature of most derailleurs of the time, the results weren't pretty, especially when the derailleurs were out of adjustment or the rider tried to shift while standing still or under pressure.

Then there were the engineering types and tinkerers who look at any mechanical device and think "There must be a better way."  And, finally, there were lots of newly-minted lawyers with too much time on their hands who saw all sorts of potential lawsuits lurking. (Some of them helped to found the CPSC.)

One of the best-remembered attempts to correct the "deficiencies" of derailleur gearing was Shimano's Front Freewheeling system.  Basically, it incorporated a freewheel-like mechanism between the chainrings and crank so that the chainrings spun as long as the wheels were spinning. This allowed riders to shift without pedaling. 

Some people who were accustomed to internally-geared hubs (like Sturmey-Archer three-speeds) liked this new innovation, which is probably the reason why it developed something of a following in Germany, where many people still cycled for transportation but few were accustomed to derailleurs.  However, the FF system was heavy and complicated, and was equipped only on entry-level bikes.

Another attempt to bypass the idiosyncrasies of derailleurs and multiple rear sprockets is all but forgotten today.  But it was interesting in its own way.

Before its foray into the bicycle business, Tokheim had about seven decades' worth of experience in manufacturing fuel dispensers and pumps, and equipment for payment terminals and retail automation systems.  So, if you've ever owned or managed a gas station, you've seen or used Tokheim equipment.

Like a few other American companies, Tokheim thought the Bike Boom was an opening for a new profitable market.  And, like those other companies (including, of all companies, Beatrice Foods!), they thought they could make bike parts and accessories even though they had absolutely no experience with them--or, it could seem, cycling. 

Then again, Tokheim's experience with pumps and other kinds of machinery had, it would seem, at least some applicability to designing and manufacturing a bicycle gearing system.  It was at least somewhat in evidence in their "Gear Maker" system.

The Tokheim Gear Maker


When drivetrains with derailleurs are shifted to their extreme positions (small chainring with the smallest rear cog or largest chainring with largest rear cog), severe chainline angles can result.  This usually results in noisier running; in worse cases, it leads to premature chain and cog wear.  In the worst cases (especially with an inexperienced and unskilled rider), the chain can be thrown off the cogs and into the wheels or get stuck between the chainrings and chainstay.

Most cyclists learned, in time, not to shift into the extreme gear positions--or to do so carefully.  However, some could never get past that first experience of a missed shift.  Or, if they had no previous experience with multi-cog systems, they were intimidated.




That is the "need" the Tokheim system was intended to meet.  Imagine an old-fashioned Ferris wheel:  the kind with a "spider" that rotates around an axle at its center and "cars" or "gondolas" at the end of each arm.  Those cars and arms are in fixed positions and will always reach the same height at the peak of their rotation. 


Now imagine that between those arms, there are other arms, except that these arms are expandable and retractable.  Thus, the Ferris wheel operator could expand the diameter (and height) of the wheel for more adventurous customers.  But the cars of those expanded and contracted cars would rotate in the same plane as the cars on arms with fixed lengths.







The gear in the "gear maker" was like that Ferris wheel.  It was operated with a twist-grip shifter.  When the shifter was in its "high" position (slackened cable), the chain ran on the smallest gear, which was fixed to the axle.  Shifting down made an interposer arm push a series of bars out successively.  At the end of each bar were teeth like those of a typical rear sprocket.  The chain ran on a larger sprocket something like the "skip tooth" cogs found on some 1970s freewheels.  A tensioner--basically a derailleur cage and pulleys--took up chain slack.

For a time, the Tokheim system came as standard equipment on a few Huffy and Murray bikes.  I never saw a bicycle sold in a bike shop that was equipped with the Tokheim system, and I don't know whether anyone ever retrofitted it to a bike.  For that matter, I didn't know anyone who rode it, and only got to work on a couple of them, so I don't know how they performed in the "real world".  However, as the gears were made of plastic, I suspect they wore fairly quickly.  And, as Tokheim stopped making it around 1980 and, to my knowledge, never offered replacement parts (and because most of the bikes that came with them have long since ended up in landfills), I don't suspect that very many Tokheim Gear Makers are in use today.  But, I think, they are interesting nonetheless.

Campagnolo Gran Sport: Act II

Yesterday, I mentioned the Campagnolo Gran Sport and its offspring.  As I said, although the original GS derailleur ceased production in 1963, the name wasn't abandoned:  It was re-appropriated in 1975.  In a way, Campagnolo came "full circle" with the Nuovo Grand Sport rear derailleur:  It shared the geometry and overall design of the Record and its succ essors, but had a cruder finish and hexagonal rather than recessed allen bolts, while the Record, Nuovo Record and Super Records were refinements of the original Gran Sport.    The 1970's Gran Sport was situated below the Record but above Campagnolo's "budget" Valentino and Gran Turismo derailleurs, which cost more than, and didn't shift as well as, Japanese derailleurs of the time.

Also, over the few years that followed the introduction of the original GS, Campy created a line of Gran Sport components: hubs, crankset, bottom bracket, headset, pedals and seatpost, but no brakes.  This gruppo is believed to be the first such comprehensive ensemble of professional-level equipment since Birmingham Small Arms (BSA) made the components-of-choice for Six-Day Racers as well as much of the peloton during the 1930s. (BSA also made some very well-respected bicycles.)  Soon, Campagnolo Gran Sport parts would be nearly as common among elite cyclists as BSA stuff had been.

A new gruppo was also created around the Nuovo Gran Sport.  It would include something the original Gran Sport group didn't have:  brakes.  (Interestingly, BSA made brakes to go with their other components, but Campagnolo didn't come out with their now-famous sidepulls until 1968, a year after the Nuovo Record derailleur was introduced.) The arms were all but identical to those of the Record.  However, the cable adjuster was a knurled dome and didn't have the rubber "O" ring seen on Record brakes.  More important, the quick release could only be opened or closed completely, in contrast to the infinitely-variable quick release on the Record, which could be opened part way.


One of the most interesting Nuovo Gran Sport components was the crankset, which had a three-arm spider:

Later, it was replaced by a five-arm spider much like that of the Record:

The headset shared the same bearings and bearing surfaces with Record and Super Record headsets.  However, the Gran Sport, made entirely from steel, had only two wrench "flats" on the top adjustable race, while Record-level headsets had multiple sides that to fit a standard headset wrench.

Some people preferred the Gran Sport because it didn't have any names or logos on the adjustable race or lower head race. In that way, it resembled the headsets found on some old British frames like Claud Butler.

The pedals were based on the Record's quill design.  The bearings and bearing surfaces were the same. However, the NGS didn't share the Record's knurling on the outside of the cone locknut that helped to prevent dirt from working its way in.  In addition, the dust caps on the NGS were plastic (steel on the Record and alloy on the Super Record) and the cutouts on the cages were a bit smaller.  Finally, as with the rear (and front) derailleurs, the finish was cruder.  However, nobody seemed to notice any difference in functionality between the Gran Sport and Record series pedals.

Possibly the most inelegant (at least to my eye) constituent of the Nuovo Gran Sport line was the shift levers.  They functioned just like the Record levers but, like other Gran Sport components, had a less-polished finish. And the adjuster nuts, while easy enough to use, were not attractive, at least to my tastes.

In contrast, the Gran Sport front derailleur was all but indistinguishable from the Record:

Finally, here is my favorite component in the Gran Sport lineup:

These hubs were part of the Nuovo Gran Sport gruppo.  But they weren't called "Gran Sport". Instead they were known as "Nuovo Tipo", the name under which they had been made since 1965, a decade before the introduction of the Nuovo Gran Sport derailleur.  The hubs were simply incorporated into the group.



I had two sets of wheels with these hubs.  In fact, my very first set of custom wheels was built around them, with Super Champion 58 rims and Robergel "Sport" spokes.  I rode them on my first long bike tours and, after a few hundred miles, the hubs spun just as smoothly as the Record hubs I would later acquire.  

TIpos shared the same bearings, cones and axles with Record hubs of the same era.  However, the inner races on the Tipos were stamped, while those on Records were forged.  That meant that Tipos weren't as smooth out of the box as Records and needed "breaking in".  They also probably didn't last as long, but I knew cyclists (myself included) who rode plenty of miles, some of them hard, on Tipos.  

More visible differences, though, were in the logo (Tipos used the older-style "flying wheel" while Records had the "world" insignia), the oil hole clips on the Records and lack of same on the Tipos, and the knurled quick-release locknut on the Tipo vs. the nut with the D-ring on the Record.

Finally, the large-flanged version of the Record had oval cutouts in the flanges, while the Tipos had portal-style holes reminiscent of classic hubs from the 1930s to the 1950s.

1977 Raleigh Competition


Probably the best-known bike (in the US, anyway) to come equipped with Nuovo Gran Sport components was the Raleigh Competition from 1977 to 1985. (Before 1977 , the Competition came with a Huret Jubilee rear derailleur and other French components.)  The NGS gruppo was, not surprisingly, more likely to be found on Italian bikes.  I recall seeing Olmos and Cioccs outfitted with the full Nuovo Gran Sport ensemble, except for the rear derailleur, which was a Nuovo Record.  Stuyvesant Bicycle  and a few other shops sold them.  I don't know whether the shops changed the derailleurs or whether the bikes were originally spec'd that way.

Whatever the case, Nuovo Gran Sport equipment, while good and reliable, never became terribly popular in the US.  I think one reason was the crude finish of some parts, especially the rear derailleur.  For about  the same price as NGS, one could buy Shimano Dura-Ace or SunTour Superbe equipment, which were beautifully finished and offered some of the features (like the infinitely variable brake quick-release) Campagnolo included in their Record series but omitted from Gran Sport.  And SunTour derailleurs and levers shifted better than their counterparts from Campagnolo.

Campagnolo finally retired the Gran Sport name and lineup in 1985, the same year the Nuovo and Super Record series ended their runs.  The Record lines were superseded by the Record-C, while the Gran Sport's berth below the Record was taken by the Chorus and Athena gruppos.  And Campagnolo stopped making their lower-end Valentino and Gran Turismo derailleurs and developed new "mass market" component lines called Victory and Triomphe.
