I Couldn't Put The Cat In My Bag

Yesterday, I managed to get out for a late-day ride:  a couple of hours spinning and making random turns on Tosca, my Mercian fixed-gear.

Although I had clip-on lights in my rear bag, I didn't want to ride after dark. So, when the sun--which, early in the afternoon had emerged from a days-long absence--tinged the sky orange, I took a shortcut back to my place through the deserted (as they are on weekends) industrial areas of Maspeth and Long Island City.

As I pedaled up a street nestled between rows of warehouses, I saw what looked like a furry shadow slinking by a construction site.  It leaped onto the crumbling brick stoop of a house that seemed to be constructed of peeling shingles.  And I heard...

Meow.  Yes, that furry shadow was feline--but not, I would soon find out, feral.  I stopped and, after I looked into its eyes for a split-second, he (by that time, I had decided  he was male) made a tiptoed sprint toward me.

I rubbed my fingers on his head.  He rubbed against my ankle.  I stroked his back.  He closed his eyes and rolled, a little, on his side.

I really knew he wasn't feral when I picked up my leg and dismounted my bike.  That motion frightens off most cats (and many other animals).  But my new friendly feline acquaintance took a step closer to me.  Finally, I squatted and picked him up.  He didn't resist.  In fact, he curled himself on my shoulder and chest.


He stayed there as I lifted my right leg over Tosca and re-mounted.  I pedaled down the deserted street, crossed another and increased my cadence just a little when he started to squirm.  


Hmm...I know that even when I was at my best, my pedal stroke was never as smooth Jacques Anquetil's or Stephen Roche's.  Still, I tried to make my motions more fluid, if slower.  The cat squirmed more, and jumped off.

But he didn't run away from me.  In fact, he almost seemed to be waiting for me to dismount and pick him up again.  Which I did.  And I remounted the bike.  And pedaled--slowly--again.  He squirmed, but never clawed me.  Not only was he not feral; he had obviously never been on a bike before!

So I picked him up again and walked, with him on my left shoulder and my right hand clutching Tosca's stem, back to the construction site. He looked, rather forlornly, as I said goodbye. (If only I could have photographed him!)

As I left, I noticed a bowl and plate by the construction site: Somebody has been feeding him.  Still, I am somewhat tempted to go back--even if my landlady really means what she said about a two-cat limit (which I had to beg for when I moved in; she only wanted to allow one).  Plus, I have to wonder how my cats would take a new addition to the "family".  Max is friendly and curious; he seemed to be thinking "Great!  A new playmate!" the day I brought Marlee home. But Marlee is still fearful and skittish; she seems to come out of hiding only for me.

I could go back with the LeTour, which has baskets on it, and a blanket or pillow.  And maybe the landlady, if and when she comes in, won't see him:  He is a smoky gray color, which means he could hide fairly easily.  Plus, Max would like him:  He likes everybody, or so it seems.  As for Marlee...

Whether You Autumn Or Fall, Please Don't Take A Header!

A few posts ago, I made a lame pun to explain why I prefer "autumn" to "fall", especially when it comes to cycling.

No one has ever autumned off his or her bike.  On the other hand, just about every cyclist has taken a fall.  

I have taken a few in my time.  None resulted in my missing any significant amount of time from riding. Ironically, the only injuries that kept me off my bike for more than a few days were not cycling-related.  Ditto for the one other event that kept me out of the saddle:  my surgery.

Of the falls I have taken, two resulted in my head making any contact with whatever I was riding, and fell, on.  

The first came when I was pedaling from Park Slope, where I lived at the time, to a school in the Bronx where I'd been conducting poetry workshops as an artist-in residence. I had just spun my way across the Greenpoint Avenue  Bridge and veered left onto Van Dam Street, in an industrial area of Long Island City, Queens.  About two blocks into Queens, a truck driver flung his door open, and into my side--causing the one and only somersault I've ever done on my bike.  Some would argue it wasn't a true somersault, as I didn't push my hands out in time to keep me from rolling on my head.

The second time, I was riding my mountain bike in Forest Park.  I was pedaling at  high-octane pace and was in my own little zone, not paying attention to my surroundings.

Well, in my path was a mound the BMXers used to flip themselves in the air.  I rode up on it--in the wrong direction, on the nearly-vertical side.  

Well, I flipped over. But I didn't flip back. Instead of landing on my wheels, as any of the 14-year-old kids would have, I came to earth upside down.

Those 14-year-olds rushed to my side.  "We really thought you were gonna die!", one of them chimed after helping me up. I never lost consciousness, but when I got up, I noticed that my helmet had broken.  In two.

OK.  So now you probably have figured out my position on helmets.  Yes, I wear them and encourage others to do likewise.  

Even though I had a helmet protecting me in each of those accidents, I count the lucky stars I didn't see when I feel that I have never taken a "header".  I hope you haven't either.

A line drawing of the world's first "header".  From Roads Were Not Built For Cars.

It seems that in the days of high-wheeled bicycles (a.k.a. "penny farthings"), "headers" were a fairly common occurrence. And, since cyclists in those days commonly rode front wheels of 60 inches (about 1.75 meters) or more, the impact from such a fall must have been even greater.  

Some would use the fact that people survived such falls as an argument against helmet-wearing.  That's a valid argument, as far as it goes.  However, there is also this to consider:  In those days, no one seemed to know much about concussions, let alone their long-term effects.

So...Yes, I will continue to wear a helmet as I cycle in autumn--and be grateful I haven't taken a "header".  At least not yet.

Mature? Not Yet: Disc Brakes On Bicycles

In the mid-1970s, my high school acquired its first computer.  The father of one of my classmates, who worked in a nearby military base, in one of those jobs he couldn’t talk about, negotiated the purchase.  For $6000, my alma mater got a used machine, about half the size of a classroom—and with about half of the capacity of devices kids carry in their backpacks nowadays.

When I graduated the following year, one of my relatives gave me a new Texas Instruments Model 101 digital wristwatch.  With its red LED display and sleek goldtone band, it seemed like the epitome of elegance and slick high-tech, all rolled up into one.  No one else I knew had such a timepiece:  For the one and only time in my high-school years, I was the coolest kid in the class.  At least, that’s how I felt.

Neither the computer nor my watch made it past my sophomore year of college.  The big box (“It’s just an oversized, overpriced file cabinet!” one parent exclaimed upon learning what it cost) assigned classes like “Sports Heroes” to honors students who signed up for the Shakespeare seminar.  (I know.  I was one of those students.) And that was the least of the computer’s malfunctions. Worst of all, nobody seemed to know how to fix them.

And nobody seemed to know how to fix my watch.  One shop claimed that displays of numbers that had nothing to do with the time of day were a result of “water damage” –only moments after I took that watch out of its box.  (I have since learned that technicians and reps say “water damage” when your electronic device is acting up or not working and  they can’t figure out why.)

Less than a decade after I graduated high school, the Yankees were giving away digital watches (with the team’s logo, of course) as promotional items on Fan Appreciation Day. My graduation gift, in contrast, sold for more (in non-inflation adjusted dollars) than most smartphones or laptops cost today.  And the watches the Yankees gave away were more reliable (water resistant to 100 meters, and shock resistant) than the one I got on Graduation Day.   

I was thinking about the computer and watch as I read an article in the most recent Bicycle Quarterly.

In “Are Disc Brakes Mature Technology? “, Jan Heine recounts his and other BQ editors’ experiences with both mechanical and hydraulic disc brakes on road, mountain and city bikes.  While the brakes on one bike offered the power and modulation of good caliper brakes, their performance was hampered by their incompatibility with the levers that came on the bike.  The brakes on the other bike were not as good as road calipers and, worse, there were a couple of potentially serious failures. 

Heine seems to think that disc brakes have potential, but there are issues that need to be worked out.  Braking power is still determined mainly by the size of the disc.  A larger disc is heavier and could necessitate larger forks—both of which are anathema to racers and other performance-oriented cyclists.  More important, though, is that while larger discs offer more power, they seem to offer less modulation.  From what Heine and others say, it seems that larger rotors give the brakes the “all or nothing” feel that V-brakes (at least the ones I’ve used) always seem to have.

The flip-side is, of course, that smaller rotors offer less power.  And, if there isn’t enough power, whatever modulation the brakes offer is all but irrelevant.

Another problem, as Heine points out, is that on disc brakes, the pad grabs the disc on the rear.  On a front fork, that means the wheel is pulled away from the dropout (or fork end).  When you’re barreling down a hill—or sluicing through traffic—few things are more dangerous than a front wheel popping out of a fork. 

Most modern quick release levers, Heine says, aren’t secure enough for bikes with powerful disc brakes.   Through-axles, like the ones found on downhill bikes, might be a solution.  But even with them, the fork blades on most non-suspension (telescoping) forks wouldn’t be stiff enough to counter the forces the brakes would put on them.  So, Heine says, a dedicated suspension fork might be the best kind to use with disc brakes.

 (In contrast, rim brakes pull the wheel slightly upward, into the dropout.  And their forces are concentrated in or near the stiffest and strongest part of the fork:  the crown.  That is the reason why properly-installed wheels don’t fall out of forks equipped with rim brakes or no brakes.)

I myself don’t plan to start using disc brakes any time soon:  I have never had trouble getting the braking power and modulation I need from rim brakes, as long as I use good cables and pads and keep everything properly adjusted.  Plus, there is something to be said for the simplicity, not to mention the lighter weight, of such brakes.  So, I hope that disc brakes don’t become the only option on new bikes or that component manufacturers stop making rim brakes and parts.

On the other hand, I am not against some bikes coming with disc brakes, or for such brakes to be offered on bikes where they might make sense.  Most of all, I hope they don’t become a de facto standard—or the only option—before they are a “mature” technology.  At least, when my digital watch failed, I still had the mechanical watch another relative gave me for a birthday—my 12^th or 13^th, if I remember correctly.  And plenty of others were available. 

Joaquin Is Going That Way...

Everybody’s been storm-watching for the past 24 hours or so.  They all remember Sandy and, from what the weather reports say, Joaquin is even more powerful.  But the wind and rain that’ve battered us today aren’t his fault:  A Nor’easter has worked its way along this part of the coast.

Joaquin, as of today...we hope!

Sandy became a “superstorm” when  merged with a Nor’easter before making landfall near Atlantic City, New Jersey.  It doesn’t seem that Joaquin will do anything like that:  He seems content remaining out to sea, well to the east of Montauk Point.  Still, he could gift our Nor’easter with even more wind and water than it might have whipped against, and dropped on, us:  As meteorologists tell us, the course of a hurricane is one of the most difficult things to predict.

There seems to be an interesting divide in how much concern people who lived through Sandy’s ravages are expressing about the prospect of another Nor’easter, hurricane or—superstorm?! From what my own admittedly unscientific observations, the folks on the South Shores of Staten Island and Brooklyn, and in the Rockaways, are bracing themselves.  Whether or not they’re making actual preparations, they are taking the reports and warnings seriously—more seriously, some admit, than they did when Sandy approached. 

On the other hand, residents of Long Beach and other communities on the South Shore of Nassau County—which, arguably, incurred even more damage than Brooklyn and at least as much as the Rockaways—seem more blasé.  As one man said, “I lost everything then.  I’m not worried now.”  But people in other devastated areas also “lost everything”.  In fact, in the Breezy Point area of the Rockaway Peninsula, houses that weren’t blown apart or washed away burned to the ground when water wreaked havoc with the electrical wires.  I recall seeing people who were able to retrieve only family photo albums before fleeing, or upon returning.

As for me:  I am watching the storms.  Aside from not having classes for a week, I wasn’t affected much by Sandy.  I want to make sure I can say the same thing about Joaquin or the Nor’easter.

Then again…Joaquin couldn’t possibly affect us as much as Sandy did.  After all, Joaquin is a male name, while both males and females are named Sandy.  Hell hath no fury like that of both genders, combined!

Vera Goes Gran Fondo

You tell yourself, "This is it!"

You're not going to buy another bike, you tell yourself.  The bikes you have are "for life".

No more changes, no more upgrades, you say.  You're not going to buy another part unless you absolutely have to replace something that's worn out or broken.  You won't buy another bike accessory, no matter how great it looks or whether you really wonder how you've lived without it. And you absolutely swear not to go to any more swap meets, spend any more time hanging out in bike shops or while away your evenings looking at bikes and parts on eBay.

And you promise yourself you won't lift another allen key or screwdriver, or squeeze your oil can or grease gun, unless you're doing maintenance that absolutely must be done to keep your bike rolling.

But you know, deep down, you're lying to yourself: Once you learn how to tinker with your bikes, you won't stop--no matter how little mechanical aptitude you thought you had before you picked up that first repair manual, that first edition of Anybody's Bike Book.

You always find something to fix, even if it doesn't need fixing.  And there's always some experiment you want to try.

So it is with Vera.  Just before I went to Paris, I had an idea:   I'd turn  her gearing from a typical "compact" road setup (well, with slightly lower gears) to something I'd never before tried:  Gran Fondo gearing.

Turns out, I had everything I needed for the experiment. Well, almost.  The crankset that originally came with Vera--a Shimano Deore triple from the late '80's or early '90's--was sitting in a box, just begging to be reunited with her.  A BBG 46 tooth chainguard/bashguard, also sitting in that same box, would look good on that crank--and on Vera--I thought.   And I had a nice Stronglight 46 tooth chainring I'd been using with my the compact double as well a Shimano UN-52 bottom bracket that, according to the folks at Harris Cyclery and Velo Orange, would work. All I'd need is a 30T chainring with a 74mm bolt circle, which I found easily enough.

I installed the chainguard in place of the outer chainring.  The Stronglight ring, made to be an outer ring for a double or triple, went on the middle position.  And, of course, the 30T ring was bolted on the inside.  

I installed the Stronglight chainring with the logos facing out, as if it were in the outer position.  That meant the chainring fixing nuts wouldn't sit flush with the surface of the ring, as the holes for the chainring bolts are countersunk on the opposite side of the ring.  That didn't seem to matter.  I've ridden the setup about 200 kilometers and it doesn't seem to be coming loose--and the nuts standing proud of the chainring surface doesn't seem to affect the shifting.

In this image, you can see the countersinking of the holes for the chainring fixing nuts.  You can also see a segment of an example of drillium at its best or most extreme, depending on your point of view!

Speaking of which:  I've shifted, well, only to see how it shifts.  I haven't ridden on the 30T ring.  But part of my intention in setting up the gears as I did--and, by the way, I set up the gears on Arielle, my Mercian Audax and Helene, my other Miss Mercian--was to spend most of my riding time on the larger ring and to use the smaller one as a "bail out" gear.

In any event, the shifting was even smoother than I expected it to be.  The Shimano 105 front derailleur from the 8-speed group is made to handle, as most modern road front derailleurs are, a 14-tooth difference between the chainrings.  Part of the reason why I haven't had problems with shifting is, I believe, that I'm using a non-indexed downtube shifter.  I wonder how (or whether) the setup would work if I were using Ergo or STI levers, or even bar-end shifters.

The bottom bracket's axle is 127 mm long.  The crank is actually made for the old-style asymmetrical axle:  The original bottom bracket is what's known as "121+5":  In other words, 5 mm are added to the right side of a 121mm axle.  Using the modern bottom bracket doesn't seem to affect shifting or my pedal position"  It just leaves more axle showing on the left side than what you see with modern cranks and bottom brackets.  However, if I keep this setup, I might splurge (if finances permit) for a Phil Wood bottom bracket with the asymmetrical axle.

In reality, riding with this setup isn't different from riding with the compact double, as I am using the 46T ring nearly all of the time.  But I think that it will allow me a greater range of gears, should I ever want or need them.

Vera seems to like it.  Truth be told, I think she likes getting the nice old crankset back.

The CPSC Is Recalling 1.5 Million Bicycles Because....

All right.  I'm going to begin today's post with another "Which is worse?" question.  The difference is, this "Which is worse" question will have three choices.

Here goes...

Which is worse: 

• a technical "innovation" that's superfluous,
• someone who doesn't know to use it safely, or 
• some government bureaucrat who doesn't know the difference?

That question entered my mind when I learned of a recall involving bicycles from thirteen different manufacturers.  

The 1.5 million bikes in question have front disc brakes.   As "The Retrogrouch" and others have said, very few cyclists actually benefit from, let alone need,  disc brakes.  

To be fair, I will point out that, although the recall was announced as one involving "bicycles with front disc brakes", the brakes themselves were not the problem.

So why the recall?, you ask. 


According to the US Consumer Products Safety Commission, which ordered the recall, when the bicycle is ridden with the quick-release lever in the fully-open position, the lever is only 6mm (or, as the CPSC notes, the width of a number 2 pencil) between the lever and the brake rotor.   

I'll run that by you again:  If you ride one of those bikes with the front wheel's quick-release lever fully opened, the lever is too close to the brake rotor.

Now, if you're going to ride a bike with quick release levers, you should know how to open and close them, and you should know enough not to ride with them open.  Forget about whether you have disc brakes: If your quick release is open, your wheel can slide or fall out from under you when you turn or hit a bump.  Or the lever can get snagged in your spokes--or, if you have a disc brake, on the rotor.

That last scenario is what prompted the recall.  Three incidents of it were reported to the CPSC.  When the lever came into contact with the rotor, the wheel came to a sudden stop or fell out of the bicycle.  One of those incidents resulted in injury.

So, because someone who doesn't know how to use a quick release got hurt, 1.5 million bicycles are being recalled.   That's good, sound judgment from the CPSC, isn't it?

Here's how you can tell if your bike is part of the recall:



 

Allen Brumm: A Cyclist Follows The Law And Is Blamed For His Own Death

Which is worse:  An ill-conceived law-- or a law enforcement official who is ignorant of, or misinterprets, a law?

The death of Allen Brumm seems to beg such a question.

The 57-year-old California cyclist was riding in a time trial when he was struck head-on by an oncoming motorist.

California Vehicle Code 21751 mandates the following:

Passing Without Sufficient Clearance 21751. On a two-lane highway, no vehicle shall be driven to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction unless the left side is clearly visible and free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be completely made without interfering with the safe operation of any vehicle approaching from the opposite direction. 

Now, I'm not a lawyer. But it seems to me that the key clause in that passage is "unless the left side is clearly visible and free of oncoming traffic for a sufficient distance ahead".  In other words, if you're driving, you're not supposed to pass unless the left lane is clear for as much distance as you need to pass.

The 35-year-old-driver had pulled to her left to pass another cyclist on County Road 19 in a rural area of Yolo County, west of Sacramento. Mr. Brumm was riding in the oncoming lane.

This is a Google Streetview of a section of CR 19 near the crash site.  As you can see, there was nothing to obstruct her view almost clear to the horizon.  

California Highway Patrol Sergeant Andy Hill, in describing the accident, said "both parties" contributed to the collision.  He did not specify the driver's culpability, but said that Mr. Brumm's fault lay in his riding "as far to the right" as possible.

This is what the Golden State's Vehicle code specifies:

Operation on Roadway 21202. (a) Any person operating a bicycle upon a roadway at a speed less than the normal speed of traffic moving in the same direction at that time shall ride as close as practicable to the right-hand curb or edge of the roadway…. 

 Again, take my reading of this, as a non-barrister, as you will.  But it seems to me that the key part of this statute--as it pertains to the accident in question--is "shall ride as close as practicable to the right-hand curb or edge of the roadway.

The last time I checked, "practicable" does not mean quite the same thing as "possible".  Were Tour de France riders to descend any Alpine road as far to the right as "possible", there wouldn't be enough riders left to continue the Tour de France!  Even the most skilled rider would have a hard time not falling off a virage were he or she to ride as far to the right as possible.

On such roads, riding as far to the right as possible could mean riding on rocks or on the edge of a cliff.  In other situations, it could mean riding on ice or on a soft shoulder that would act as quicksand under a bicycle tire tread.

That last scenario is--from what I've read--what Mr. Brumm encountered.  Riding as far to the right as possible would have meant not riding at all.  So he rode as far to the right as was practicable in that situation.

Once, on a ride in Pennsylvania, I got into an argument with an officer about that very point.  The Keystone State, like many others, has (or had, at that time) language similar to CVC 21202 in its laws.  To the right of the roadway on which I was riding was the muddy bank of a stream, which would have been all but impossible to ride on the road bike I was pedaling.  That road was similar to the one on which Mr. Brumm died--a two-lane county road in a semi-rural area.

I explained to the policeman--who, I believe, was not a cyclist--the near-impossiblity of riding "as far to the right as possible".  He said, "Well, maybe you shouldn't be riding this road."  I think he knew that I didn't live in the area and, to his credit, suggested another nearby road, which I rode back to the bridge in Uhlerstown.

And, of course, I rode as far to the right as was practicable into New Jersey.  Poor Allen Brumm did the same in California and is being blamed for his death.

My sincere condolences to his friends and family.

Saluting An Early Morning Fog

This morning, on my way to work, I pedaled into a horizon of light, high fog.

The air was still pleasantly cool and, surprisingly, didn't seem very humid.  At least, I was pedaling at a vigorous, if not furious, pace because I could, and I wasn't sweating.

Perhaps it had to do with the stillness of everything around me.  They say this city never sleeps.  Well, sometimes I'm out before people--and machines--have awakened:

Or are they saluting the skyscrapers, veiled in mist on the other side of the river ?

Oh, it's such a treat to ride my bike to work!

Less Stressful Than The Greenway

 

Yesterday, after co-leading a workshop in the Bronx, I had an errand in Chelsea. The ride, about sixteen kilometers, would have taken me across the 145th Street Bridge and up a couple of short but fairly steep climbs in the Sugar Hill and Strivers' Row sections of Harlem.  Then I would descend, probably at 129th or 125th Street (Believe it or not, they intersect in the far western section of Harlem!), under the IRT Viaduct to the Hudson River Greenway, which I would have ridden down to 18th Street.

I followed the itinerary I've outlined up to the hill climbs.  Yes, I did pedal up them, and felt invigorated on a mild autumn afternoon, but decided to ride down the "Valley"--Manhattan Avenue--from 125th to 110th Street before turning toward the river and Greenway.

At 110th, I took a quick left on Riverside Terrace and rode (the wrong way, but there was no traffic) a block, where I crossed Riverside Drive and entered Riverside Park and, finally, the Greenway.

Hudson River Greenway

I shouldn't have been surprised that so many people were cycling, running, strolling,skateboarding, rollerblading, riding Segways, walking themselves and their dogs and stopping to kiss their loved ones along the Greenway on such a beautiful Saturday.  And, really, I can't begrudge any of them:  Only a mole wouldn't want to be outdoors, by the river, on a day like yesterday.

But some of the strollers, skateboarders and others were--not surprisingly--texting.  Actually, a few looked as if they were playing video games or doing other things that required them to interact only with their electronic devices.  Perhaps it's because I came of age in an era of high crime and was victimized a couple of times---or, maybe, because I grew up without the electronic devices--I still can't understand how people can walk, skateboard or whatever and text at the same time.  I simply can't divide my attentions in that way and--again, this may be a result of having lived through the age of "Fort Apache, The South Bronx"--I feel that I must remain aware of my surroundings.  
Only the cyclists and runners seemed to be going about their way without electronic distractions.  

To be fair, most people moved aside when they heard me. A couple of knuckleheads wouldn't get out of my way even after I rang my bell and shouted, and they seemed to make a point of making it impossible to maneuver around them.  

After dodging and weaving for a few minutes, I exited the Greenway at 96th Street and started riding down Riverside Drive.  I pedaled all the way to its southern end, at 72nd Street, without seeing a single driver of a car, bus or other motor vehicle.  In fact, the only vehicles I saw were parked along the side of the drive.

Then, after turning left on 72nd and right on West End Avenue, I encountered another major thoroughfare that was all but traffic-free.  To my knowledge, neither WEA or RD was closed to traffic.  Nor was 11th Avenue, which is what WEA becomes south of 59th Street.  There, I played tag with a few cars and a couple of buses--probably going to some event or another at the Javits Center--but stopped only once--at 34th Street, one of the busiest streets in Manhattan--on my way to 18th and 9th Avenue.

I still can't get over the irony of it all:  Riding the streets from 96th to 18th was actually relaxing--almost bucolic, really--in comparison to the Greenway.

SunTour's Achilles Heel

We all have heard of the "Achilles heel":  a weakness that causes the downfall of an otherwise strong person or thing.

We have all heard--probably from a junior high school teacher--the origin of the phrase:  After giving birth to Achilles, his mother Thetis tried to make him immortal by dipping him into the River Styx.  As she dipped him, she held him by his heel--which, of course, remained untouched by the magical waters.

Until I read the Iliad for myself, I--like most people--assumed the original myth about Achilles said that his weak spot was his heel.  However, the Iliad identifies his weakness as his pride; the first story to say that his weakness was in a part of his body was Ovid's Metamorphoses, published more than a millenium after the Iliad.  Roughly half a century after that,the Roman poet Statius was the first to imply that it was his heel.

Practitioners of traditional medicine all over the world have said that pride, as well as other emotions such as anger, manifest themselves in the body.  Perhaps, then, it's not a stretch to say that organizational pride or overreach can become the "Achilles heels", if you will, in the products they make. 

SunTour VGT-Luxe rear derailleur,  circa 1973

Such was the case with a bicycle part from a company that had enjoyed enormous success for two decades.  From the time SunTour introduced the slant-parallelogram rear derailleur in 1964, it took both the original-equipment and replacement-parts market by storm; by the end of the 1970s, the traditional European derailleur manufacturers commanded only small niches of the bicycle market.

But there were clouds on the horizon for SunTour.  For one, its patent on the slant parallelogram would expire in 1984.  Other derailleur manufacturers were waiting with bated breath; practically the minute the patent expired, Shimano would incorporate SunTour's design into its SIS derailleurs. Campagnolo would follow suit when it developed its first intergrated indexed shifting system.  

Huret Duopar rear derailleur, circa 1981

Another sign of trouble preceded the end of its slant-parallelogram patent:  Huret's introduction of the Duopar rear derailleur.  Frank Berto, who had so lavishly (though not unjustly) praised SunTour derailleurs for the better part of a decade, pronounced the Duopar as the best wide-range touring derailleur available.  The majority of SunTour's market in the 1970s and early 1980s was bicycle tourists and other cyclists who wanted and needed wide-range gearing.  The Duopar represented the first viable threat to SunTour since its first GT derailleurs were introduced during the late 1960s.

There was, at least, a silver lining in the Duopar cloud:  Huret's new wide-range touring derailleur indeed shifted flawlessly over the widest gearing available at the time--at least, when it was new.  But its double-parallelogram (hence the name Duopar) design necessitated more robust materials and construction than Huret offered.  So, it would rather quickly develop play and slop in the joints, especially if it was ridden in rain and mud, and would typically last about 2500-3000 kilometers.  

SunTour wanted to re-establish itself as the go-to derailleur company for dedicated bicycle tourists.  While the Duopar shifted better--when new--than any other wide-range derailleur, it wasn't that much better.  Apparently, the designers at SunTour figured they could develop a derailleur that would out-shift and out-last--and, by the way, look more elegant than--the Duopar.

The folks at SunTour, I imagine, also must have been thinking that such a derailleur would take the then-nascent world of mountain biking by storm:  the Duopar was simply too fragile, and the derailleurs Shimano made at that time didn't shift nearly as well.

SunTour Superbe Tech, 1983

So, in 1983 SunTour came out with the Superbe Tech rear derailleur.  Like the Duopar, it had a double pivoting system.  The difference was that, instead of a second set of pivoting  parallelograms attached to the main one (as the Duopar had), the Superbe Tech featured a spring inside the upper pulley wheel.  That meant, of course, that the pulley wheel had a much larger "drum" than the upper pulley of any other derailleur and was therefore not interchangeable even with the pulleys of other SunTour derailleurs.  

But its sizing isn't the only thing that made it an "Achilles heel."  The spring was not adequately protected from dirt, mud, rain or anything else one might encounter. So the spring and pulley drum would become clogged, which in (relatively short) time would cause the pulley wheel to seize, and the spring to fail.  Even the most dedicated shop mechanics couldn't fix it--or the fully-enclosed main parallelogram, which had even more complicated internals. 

The spring-loaded pulley wheel helped to make the Superbe Tech the best-shifting derailleur available--when it was new.  But, after some use, the pulley wheel  would seize up and turn the derailleur into a paperweight.  

In trying to defend itself against an onslaught from its competitors, SunTour created a derailleur with a sophisticated design and elegant appearance that indeed shifted better (in part, because it eliminated the need for cable housing) than any other derailleur--when it was new. However, just as Thetis didn't think to dip her son a second time to ensure that his heel would be soaked with Stygian water, the folks at SunTour apparently didn't go back and correct the weakness inherent in their new design.  So, in trying to protect themselves from the threats imposed by Huret and, later, Shimano, they made themselves vulnerable in a seemingly-small area.  

While the Superbe Tech's flawed pulley wheel did not, by itself, cause the demise of SunTour, many in the world of cycling believe it was where SunTour suffered its first debilitating wound.
