Before Carbon Fiber: Plastic Bicycle Components

Early in the 1970's Bike Boom, boatloads of ten-speeds from Raleigh, Peugeot, Motobecane, Dawes and other European makers came to these shores.  You may have had one of those bikes; perhaps you have one now. 

If it was made before 1975, chances are that its derailleur was made by Campagnolo, Huret or Simplex.  The latter company supplied the derailleurs for most Peugeots until the early 1980's, as well as for some models from the other bike-makers I've mentioned.  My Peugeot PX-10 came with the Simplex Criterium; the entry-level U-08 came with the company's "Prestige" mechanism.

Simplex Criteriun

In design and function, the Criterium and Prestige were the same.  The Prestige had a red-badged parallelogram while the Criterium had silver badge and cute red plugs in the pivot bolts.  Most interestingly, though, the parallelogram and knuckles on the Prestige were made entirely of Delrin plastic, while the Criterium's parallelogram had a steel reinforcement.

Simplex Prstige

Because of the materials used, Simplex derailleurs were often perceived to be "cheap" or of low-quality.  Actually, given the standards of what was available at the time, they shifted reasonably well--not as well as anything SunTour made, but at least as well as most of Campagnolo's offerings.  The chief objection to those plastic Simplex derailleurs was, aside from aesthetics, their durability.  When I worked in bike shops, I saw many on which the plastic had worn at the pivots and joints, leaving them with sloppy shifting.  In all fairness, though, I must admit that I didn't see as many broken ones as I expected, and I think stories of Prestiges or even Criteriums that exploded under normal pedaling pressure were exaggerated.

From the time the first all-plastic (except for the cage plates and bolts) Simplex derailleurs were introduced in 1962, increasing amounts of metal were added to the higher-level models.  Lucien Juy probably figured that racers and tourists rode more miles and under worse conditions than recreational riders did, so more durable derailleurs were necessary for them.  (While a Prestige would wrap up the amount of chain necessary for a triple crankset, it wasn't torsionally rigid enough to last very long in such use.)  By 1975, he had come full-circle:  His "Super LJ" was constructed entirely of alloy and intended to compete with the Campagnolo Nuovo Record, Huret Jubilee, SunTour Cyclone and other top derailleurs of the time.

(This state of affairs may have made Simplex the only component manufacturer whose professional-level wares were heavier than its entry-level stuff, or anything in between!)

Before carbon-fiber frames gained widespread popularity, Simplex derailleurs were among the few components to be made of plastic.  Another is one that, unless you were riding during the '80's, or have a bike from that period, might surprise you.

Stronglight cranks and headsets came on many of the same bikes that included Simplex derailleurs.  I never had any problems with the ones that came with my PX-10E; in fact, I have a soft spot for the Stronglight "93" crankset.  (The only reason, I believe, it's not popular today is its proprietary bolt circle of 122mm.)  The headset was ugly but at least it was smooth-running, sturdy and didn't require any special tools.

Stronglight A-9

Later, Stronglight made what some regard to be the best headset, ever: the A9. (The "Delta" is the A-9 with more seals and more smoothly curved cups.) I had one on my Mondonico Criterium; it was as well-made as anything I've ridden.  Many 30-year-old A9s are still in use today and people pay premium prices for them on eBay.  It's the headset I'd still be using if it weren't for Chris King.

Stronglight B-10

Although it was the lightest headset available at the time (and lighter than most headsets available today), someone though a lighter version was necessary.  So was born the B10, which shared the A9's tapered roller bearings but replaced the alloy cups with ones made out of--you guessed it--Delrin.

(The B10 sometimes bore the name of Tour de France champion Bernard Hinault on its locknut.)

I never used a B10 myself, and I never installed one. However, it came on some of Trek's touring machines during the 1980s, as well as other bikes.  Not surprisingly, they ran as smoothly as the A9s--at least for a while.  Accounts vary on how long.  But because roller bearing headsets are tightened with more force than ball-bearing headsets, owing to the tolerances of the roller bearings, tightening compresses the plastic cups more than it does to alloy ones.  From my limited experiences of working on B10s, I found they were more difficult to adjust so that they turned smoothly without play. 

I heard a few accounts of cups that broke.  If they were true, I wonder how many were the result of failure during a ride or of over-tightening. Or both.

B10s, apparently, were not in production for very long.  On the other hand, Simplex made plastic derailleurs for more than two decades.  That could be the reason why we see more extant Simplexes than B10s.  That, and the fact that during the Boom, many people bought ten-speed bikes, rode them once or twice and relegated them to basements and garages for decades afterward.  Then again, the same could be said for some of the Treks that came with plastic headsets:  People bought them for tours they planned but never did, or they actually did their planned tours and, afterward, their lives took them away from cycling.  Or thet simply found they didn't like bicycle touring.

In any event, it seems that--unless you count carbon bikes and parts as plastic--there have been few, if any, attempts to render major bicycle parts in the material during the past three decades or so.  Could it be that carbon bikes are really a disincentive for parts manufacturers to make plastic components and accessories to be used on non-carbon bikes?  Or is it--as rumors have it--that plastic derailleurs, headsets and other parts really disintegrate under you as you ride, or break at the worst possible moment?

What They Did Before And After They Raced: Jean Hoffmann and Jacques Anquetil

An article in BicycleQuarterly No. 54 outlined the life and career of Jean Hoffmann.

Chances are, unless you’ve read BQ 54, you haven’t heard of him.  I hadn’t either, until my copy of the magazine showed up in my mailbox. On the other hand, anyone who has followed bicycle racing for as long as it takes to lap the Arc de Triomphe has heard of someone who “served in the trenches”, if you will, with him.

That compatriot is none other than Jacques Anquetil, the first five-time winner of the Tour de France.

They rode for the same team—the legendary Raphael Geminiani —though not at the same time.  They did, however, serve together with the same French Army battalion in Algeria.  (At that time, even such luminaries as Yves St.Laurent had their careers interrupted for mandatory military service.)  Although Hoffmann crashed and was dropped after the 14^th stage of the only Tour he rode, in 1959,  he arguably was, in his own way, as much of an iconic figure of French cycling in the 1950’s and ‘60’s.

In those days, someone who won amateur hill-climbing competitions like the Poly de Chanteloup or rode at or near the head of a major randonnee like the Paris-Brest-Paris could garner nearly as much attention as the professional riders who won multi-day racers (which France certainly didn’t lack!) enjoyed.  In fact, Hoffmann was known in the cycling press—a major part of the French media at that time—before anyone heard of Anquetil.

It didn’t hurt Hoffmann’s popularity that he so dominated the qualifier for the Poly—on, as he recalls, a heavy old bike with a single chainring and “way-too-large gears” at age seventeen that Rene Herse loaned his own bike to Hoffmann for the actual competition.  It almost goes without saying that Herse was delighted to have Hoffmann on his team—so much so that he gave Hoffmann a velo de service that was chromed, like Rene’s own, rather than the typical Herse blue (a lovely color, by the way) other team members received.

After riding on Herse’s team for a few years, Hoffmann couldn’t resist the urge to race.  He quickly found success, mainly because of his climbing abilities.  One of his major successes was winning the climber’s jersey in the 1955 Peace Race, often nicknamed “the Tour de France of the East”.  He was selected to ride in the 1956 Olympics.  But, fate intervened:  He—and Anquetil—were drafted.

After completing his military service, Hoffmann continued his racing career, turning pro in the year he rode his only Tour.  He would retire from racing after three years.  He never stopped riding, though:  He rode gentleman races—which pitted young riders against older ones and gave the latter a handicap based on his age—as well as rides like the Audax and Randonee Paris-Brest-Paris.  Today, at age 81, he does a 50 km ride (which includes at least one climb) every day. 

Interestingly, he rides a Look carbon bike.  He has no interest in machines like the one he rode for Herse’s team in the ‘50’s.  In those days, it was the most technically advanced bike available; being a racer at heart, he moved on to what technology offers today.

As we all know, Jacques Anquetil not only rode in the Tour; he would become the first cyclist to win that race five times.  No one disputes that he is among the handful of greatest racers of all time: in the same league as Eddy Mercx, Bernard Hinault, Gino Bartali and a few others.  He retired in late 1969. 

In contrast to Hoffmann, Anquetil did not come to racing from the world of randonees and other such endurance rides.  He also didn’t retreat to that milieu.  In fact, Anquetil got on his bike only three times after retiring.  “I have done enough cycling,” he declared. He died in 1987, at the age of 53.

After reading the BQ article, I have the impression that Jean Hoffmann might live to be 100—and won’t stop riding!

Going Dutch In The Snow

Yesterday, for the first time in years, I didn't anyone riding on the streets.  Today there were a few people pedaling; I think they were all making deliveries.  

The cold, snow and wind were enough to keep most people off their bikes.  However, I think that fear was also another factor in keeping cyclists off the road.  

Even under optimal conditions, cyclists (at least here in the US) are seen as "crazy".  Of course, someone who imputes insanity to others is portraying him- or her-self as sane or right and, by implication, entitled.  Thus many motorists see themselves as the rightful owners, if you will, of the streets and roads.  They expect cyclists to defer to them or simply to get off the road altogether, ostensibly for their own safety but actually to, as a British neighbor of mine says, to "keep up that All American idea that everything should facilitate the movement of automobiles".

Now, I know that there isn't much of a comparison between my hometown of New York and a city like Utrecht in the Netherlands.  Still, I think the following video of cyclists commuting in the snow in the ancient Dutch capital can offer some lessons to American urban planners:
