As Smooth As Friction

    • SunTour VGT rear derailleur 
    • Shimano Titlist front derailleur 
    • Huret shift levers (similar to Simplex retrofriction )
    • Stronglight 93 crankset and chainrings 
    • SunTour Pro Compe freewheel
    • Sedis “sedicolor” chain (gold, to match the freewheel!)


    • Huret Jubilee rear derailleur 
    • Campagnolo Super Record front derailleur 
    • Simplex retrofriction (“teardrop “) levers
    • Campagnolo Super Record crankset and chainrings 
    • Maillard 700 freewheel 
    • Regina chain
    So what do those two lists have in common? Each of them comprised the drivetrain on one of my bikes. The first ran on an iteration of my Peugeot PX-10 when I repurposed it as a touring bike. The second graced the Colnago Arabesque I rode for much of my inglorious racing career!

    One thing you’ll notice is that neither set was composed entirely of parts from the same company. Until the mid 1980s, that was the norm, as no component manufacturer—not even Shimano or Campagnolo—offered a truly complete “gruppo”: Neither company’s lines included chains, and Campagnolo didn’t offer freewheels.

    Another reason why most were casseroles , so to speak, rather than purées is that, for the most part, one firm’s derailleurs could be used with another’s shift levers, freewheels, chainrings and chains. It also didn’t matter if you switched from, say, a six- to a seven-speed freewheel: As long as your derailleurs could handle the range (smallest to largest cogs) and the total gear difference (the combined range of your front chainrings and rear sprockets), it didn’t matter that the other parts weren’t from the same maker.




    That all changed 40 years ago, when Shimano introduced SIS: the system with shifters that “clicked.” It
    worked extremely well—as long as your freewheel (or cassette) cogs, chain, derailleurs, shifters and cables were all Shimano SIS. (Many of us soon discovered that Sedisport chains worked as well as, and lasted longer than, Shimano’s offerings.) By the end of the decade, nearly all new bikes had SIS or its variants, two of which I’ll mention. “If it doesn’t click, it won’t sell,” became a bike industry mantra.

    Seemingly in a panic, Campagnolo and SunTour offered their own “click shift” systems. (SunTour actually made one in 1969. It reportedly worked well, but the still-relatively-small derailleur-equipped bike market wasn’t ready for it.) Both failed—Campagnolo’s Syncro system was panned as “Stinkro”—for essentially the same reason. While Shimano designed an integrated system, it seemed that Campagnolo and SunTour simply made indexed levers. The “clicks” didn’t always mesh with the gear change because they were the calibrated to the distance between the cogs. 

    Campagnolo’s Syncro wasn’t produced for very long and seems to have found popularity mainly among collectors. “Campy” was able to redeem itself during the ‘90’s, when it made an integrated system (with Ergo levers) that worked well. SunTour, on the other hand, never recovered from its failed system (and, to be fair, other missteps). Its reputation was made worse because bike-makers like Schwinn used their old stocks of French cables and chains that didn’t play nice with SunTour’s click shift.

    SunTour’s fate is a particularly sad irony when you consider that a generation of cyclists like me could replace a malfunctioning Huret Allvit, Simplex Prestige or Campagnolo Valentino or Gran Turismo—or an ailing Atom or Regina freewheel—with something from SunTour without re-doing the rest of the bike.

    Part of the reason why that was possible was “friction “ shifting, as Eben Weiss points out in his latest Outside article. He cites that compatibility as the reason why, after decades of using indexed shifting and a brief fling with electronic changers, he’s converting all of his bikes to friction shifting.

    I may do the same. It wouldn’t be difficult, really.Of my seven bikes, five have derailleurs. (The other two include a fixed-gear and single-speed.) Two of the five shift with Simplex retrofriction levers. The other three—Dee-Lilah (my Mercian Vincitore Special), La-Vande (King of Mercia) and Vera (Miss Mercian mixte) have Dura-Ace 9-speed downtube levers. I’m using them in indexed mode but they can be converted to friction levers simply with a turn of the adjuster ring. I would do that, of course, if I were to use 8- or 10-speed cassettes instead of the 9s I’m currently running.

    The Best Kind Of "Retro": Simplex "Teardrop" Shifters

    Yesterday I wrote about what may have been the most jewel-like bicycle component I ever rode:  the Huret Jubilee rear derailleur.

    Today I'm going to write about the part that might be a close second in the beauty contest.  I mentioned them in yesterday's post:  Simplex "retrofriction" levers--in particular, the "teardrop"-shaped ones. 



    Most retrofriction levers in that shape were made to fit brazed-on lever bosses. I rode with those levers on several of my bicycles, including the Colnago Arabesque and Miyata 912.  The levers were also available in other configurations, including a "coke spoon" version made for Gipiemme.  



    Simplex also made the levers in other shapes and colors for Mavic, Galli and other component manufacturers.  And, of course, there was the original version, which was usually attached to a clamp but was also available to fit braze-ons:




    Although they all functioned in the same way, the Gipiemmes might have offered the best hand-feel.  (I am only guessing, as I never tried them myself.)  But whatever their shape, they offered the smoothest action of any lever I've ever used.  That is because they had a spring-clutch mechanism on the inside that kept the lever from slipping (and, thus, the derailleur from shifting accidentally) but allowed a shift with a lighter touch than was needed for other levers.  

    Campagnolo and other friction levers, on the other hand, relied on nylon bushings and D-shaped screws to hold them in place--which made them more balky to shift.   The ratcheted SunTour levers were like Simplex's retrofrictions in that they,too, stayed in place when they weren't shifted but were easy to shift.  However, they had a clunkier feel and it was a bit harder to fine-tune shifts on them in much the same way that a one-bolt seatpost with notches is more difficult to adjust to exactly the right seat angle than one without notches, or a two-bolt post.

    So, SunTour's "power" shifters tended (at least in my experience) to work better with wide-range slant-pantogaph derailleurs on which only the lower pivot was sprung like the SunTour's VGT or Cyclone GT.  On the other hand, Simplex's more nuanced action seemed to work well with just about every derailleur, with narrow-range racing or wide-range touring gears.  But they seemed especially well-suited to derailleurs that required smaller amounts of cable travel, such as the SunTour Cyclone S and Superbe, Campagnolo Record--and, of course, the Simplex Super LJ.

    And, oh, yes, the Huret Jubilee.  It and the retrofriction levers seemed to go together like croissants and coffee.  The original Jubilee levers were made with a large drum that pulled too much cable for the Jubilee, which caused it to overshift.  Later, Huret made a lever with a smaller drum that was intended for both the Jubilee and the titanium Success rear derailleur.  But Huret's lever operated on friction, so Simplex's shifter was smoother.

    If I were going to set up a bike with friction shifting, I'd definitely want the retrofriction levers.  However, that would mean using no more than seven cogs in the rear:  what made them so pleasant to use with derailleurs like the Jubilee is the small drum, which cuts down on the amount of cable the levers can wrap up.   In other words, even pulling the lever all the way back probably won't get it to shift onto an 8th cog.  (At least, it didn't on my bikes.)

    But, of course, if I wanted to choose components purely on aesthetics, I would choose the Simplex retrofriction levers--and Huret Jubilee rear derailleur.

    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.

    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. ;-)

    Shifting Gear

    If you've been following this blog for the past couple of weeks or so, you may have noticed some ever-so-subtle changes to my bikes.  I have documented how Arielle traded a triple crankset for a Sugino Alpina double. Well, I've also installed an Alpina double, albeit with different chainrings, on Helene.


    And you may also see that I have Carradice Barley bags on all three of my Mercians. (Tosca, as well as Arielle and Helene.)  I think I may just leave them on the bikes, as it will make it easier to carry my camera, notebook and an extra layer of clothing, if I need it.  I can also pick up some goodie or another in a bakery or flea market en route!  So, the Bike Burritos I had been using are inside the pockets of the Barleys.  I liked the way the Burritos looked on the bikes, but they also serve nicely to keep my tools and tubes organized and separate from whatever else I put in my bags.


    Finally, there is this change I made on Helene:



    I purchased a pair of shifter pods from Velo Orange. They function in the same way as the ones Paul Components makes.  However, VO's cost a good bit less and fit a wider variety of handlebars.  The VO Porteur bars on this bike are of the same diameter as road bike bars. (Most flat and upright bars are the same diameter as mountain bike bars, which are of a smaller diameter.)  


    The problem with Paul's--and many other thumb shifter mounts--is that they will fit one type of bar of the other.  But the ones made for road-bike bars will fit only on the "sleeve" of the bar, which is the section nearest the stem clamp.  That "sleeve" is a wider diameter than the "body" of the handlebar. 


    Of course, one probably could put a shim or tape underneath  a Paul clamp.  But who wants to do that after spending 75 dollars for the pod?


    The VO pod has a hinged clamp instead of the solid clamp found on the Paul pods.  That, of course, allows for greater adjustability.  Plus, VO supplies the pods with some nicely-machined aluminum shims.  And, for those of you who care, the VO pods are silver, while Paul's are black. 


    The pods are made to be used with Dia Compe Silver downtube shifters, which is what I had been using before I bought the pods.  I happen to like the lever very much, so I was happy to keep it.  I was able to mount the shifters so that I could reach them as I was holding the straight part of the bar, which is where the brake levers are located.  As I have them mounted, I can actuate the brakes with two fingers and the shifter with one.


    As much as I like the position,  I'm still getting used to the shifting.  A basic rule of thumb is:  The longer your cable, the slower, less precise and less crisp your shifting.  That is one reason why you just about need either a ratchet mechanism (like those on the Silver levers, or the old Sun Tours), a retro-friction mechanism (as used on the Simplex "teardrop" levers) or an indexed mechanism (as found on Ergo and STI levers) if you're using a handlebar-mounted shifter. 


    I think that I should be accustomed to this setup fairly soon.  After all, I once had a bike with Sun Tour shifters that mounted on top of the bars.  After a while, I found the shifting just as predictable, if not as quick, as on my bike with downtube shifters.


    And, oh, yeah, the bright pink Cinelli tape. Turns out, the gray tape I had on the bars wasn't long enough once I installed the new shifters.
