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.

    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. ;-)
