You're Definitely Not Square If You Use This Cage!

If you were riding before the 1990s, chances are that you used a water bottle cage that looked something like this:

You might still be carrying your libations in such a cage.  There's no reason why you shouldn't.  That you and other cyclists are still riding with such cages is a testimony to their design.

If you have been riding with such a cage for so long, you probably know its design was based on this:

Specialites TA Ref 215

Made by Specialites TA of France, it holds a distinction very few bicycle accessories--and only a few components--can claim:  It was the choice of racers, tourists, "rough stuff" and recreational riders alike.  Whether you pedaled your Cinelli in the peloton, your Herse over the hills or your Mercian through the moors, you used the TA Ref. 215 cage--or, later, the alloy 417. (The 215 was made from chromed steel.)  

Ref. 213

For a time, TA's Ref. 213 cage was also popular until handlebar-mounted cages fell out of favor.  And, in the 1970s, the single-clamp 216 became popular with cyclists whose frames didn't include brazed-on bosses for bottle cages.

Ref 216

I thought I knew the Specialties TA line well.  (After all, when you get to be my age, and cycle for as long as I've been riding, there are times when you think you've seen it all!)  But, in hunting for small parts and accessories for the Trek I'm building, I came across this:

Ref. 218

I have to admit that I have never seen one in person.  I tried to find more information about it, but all I could find was a listing on the Blackbird website.

The eBay listing describes the cage--Ref 218-- as having "an unusual rectangular shape."  Apparently, it was made to fit the Ref. 220 and 222 "randonneur" water bottles, which look like old-fashioned milk bottles rendered in blue anodized aluminum rather than glass. 



Ref. 222 (1 liter; Ref 220 was the .75 liter version)

Someone--Fred "Fritz" Kuhn of Kopp's Cycles, I believe--told me that TA stopped making aluminum bottles because they would oxidize on the inside and poison their users.  I wonder, though, what it was like to use bottles in that shape.  How easy or difficult were they to pull out, or push back in, the cage?

The seller says that modern Fiji water bottles fit into those cages nicely.  I'll take his/her word, though I generally don't buy Fiji, or any other water transported from the ends of the Earth.   I feel certain, however, that the 218 is bomb-proof, as all of the other TA cages were!

In Any Language, It's Just A Snow Day

Bonjour, Maman.  Comment ca-va?

Where are you calling from?  France?  Canada?

Oui.  Je suis sorti des Etats-Unis.

My mother doesn't speak French.  So she knows that when I say anything in the language, I am:  a.) recounting a conversation with one of my friends in France, b.) recalling some other encounter in a Francophone land or c.) playing a joke.

Today, she knew it was "c" but she confessed that, for a moment, I'd "flown the coop", if you will.  And, if I did, she probably wouldn't blame me, as she shares my disdain for the President whose name I dare not say.

Then, after telling her I am in Canada, I laughed.  "Well, not quite.  But the conditions at the moment aren't much different.

Yesterday afternoon, students e-mailed to ask whether my classes would be in session today.  My response, of course, was that they would be if the college were open.  I knew that snow had been predicted, but I didn't know that by mid-afternoon, the National Weather Service was predicting blizzard-like conditions.

Astoria under the weather

Last night, the decision was made to close the college, and the university of which it's a part, today.  And the snow is even more intense than what was predicted last night.  It's all the more amazing when one considers that yesterday afternoon, it was sunny and the temperature reached 17C (64F).  

How much is it snowing?  Even Citibike, this city's bike share program, shut down.

Hmm...Maybe they have to allocate part of their budget for studded tires or tires with chains.

From A Late Night, Into The Mists

Last night, I stayed at work a bit later than I expected.  What that meant was, among other things, encountering less traffic than I usually see.

It also meant dealing with a change in the weather.  In the morning, I rode to work in a drizzle that occasionally turned into rain.  But, by the time night rolled around, a dense fog blanketed the city.

Normally, I can see the towers on the Queens spur of the RFK Memorial Bridge as soon as I make the turn from 132nd Street onto the Randall's Island Connector.  At that point, the entrance to the RFK Bridge lane is about 1 3/4 miles, or about 3 kilometers, away.  

Last night, though, I could not see the towers or cables until they were right in front of me--when I was in the lane.

When I reached the middle of the bridge, over the waters of Hell Gate (which I couldn't see), I looked back at the soccer field on the Randall's Island shore:

and ahead to the Queens side

My apartment is in there, somewhere!

The Limit: Whether Or Not You're Detected

In your travels, you have no doubt seen something like this:

Such speed limit detectors usually show your speed in amber lights, unless it is over the limit, in which case the number flashes in red.

Have you ever noticed that these devices sometimes register your speed when you are riding a bicycle--but sometimes they don't?

Those of you who are engineers (or simply more tech-savvy than I am) may be able to provide an explanation of why.  I have always surmised that it had something to do with the position of the speed detector:  The ones placed above the traffic lanes don't register bikes riding on the shoulder or even the far right side of the traffic lane.   Then again, I've seen detectors on the side of the street or road--and, in a couple of cases, right in the middle of a bike lane!--that did not track me.

An article in the IEEE Spectrum--the journal of the Institute of Electrical and Electronics Engineers--may shed some light on why this is so.  

In it, Spectrum contributing editor Peter Fairley describes the advances made in detection systems used in robotic (self-driving) cars.  The best such systems could spot only 70 percent of cars just a few years ago.  Now that figure is nearly 90 percent.  Similar improvements in noticing pedestrians, and even birds and squirrels, have come.

In contrast, those same systems can detect a bicycle from 59 to 74 percent of the time.  While that is an improvement from a few years ago, the advancement doesn't come close to what has been accomplished in tracking other beings and objects.  

According to University of California-Berkeley research engineer Steven Shladover, "Bicycles are probably the most difficult detection problems autonomous vehicle systems face".  Down the coast, in UC's San Diego campus, visual computing expert Nuno Vasconcelos offers a possible explanation as to why:  "A car is basically a big block of stuff.  A bicycle has much less mass" and, he says, "there can be much more variation in appearance--there are more shapes and colors and people hang stuff on them."

Vasconcelos' explanation makes sense, as far as it goes.  In the article, however, Fairley posits that part of the problem is how those systems are "trained".  Actually, they "train themselves", if you will, by studying thousands of images in which known objects are labeled.  Most of the training, Fairley says, has concentrated on cars, with very little on bicycles.  

I will not address the question of whether robotic technology can or will replace human drivers:  Folks like the ones Fairley cites (or, for that matter, Fairley himself) can say far more about it than I can.  From what I've read, however, I believe I can surmise that self-driving technologies have a better chance of working on Interstates, Autobahns, Autoroutes or other high-speed, multi-lane highways where bicycles are seldom seen, or are banned outright. 

Likewise, detection technologies have a better chance of detecting speeders on such highways than they have of catching me riding my bike over the speed limit on city streets!

Riding With And Without Trigger

Believe it or not, there was a time in my life when I could hear the word "trigger" and not think about shifters.  For that matter, there was even a time when that word would not bring firearms to my mind.

The reason for that is that I was born a little too late to watch '50's TV shows and movies when they first ran.  I did, however, get a fairly steady diet of them in reruns.  It seemed that whenever you flipped the channels, you could find an episode of  "I Love Lucy" or "The Honeymooners".  Or "Lassie" or "Dragnet".  And, of course, there were the shows that continued to produce original episodes well into my childhood, and even on the eve of my puberty:  I am thinking now of "Perry Mason" and "Leave It To Beaver".

It also seemed impossible to escape from showings of  films like "The Ten Commandments" or "Ben Hur".  Another movie that, as I recall, often showed on the small screen was "Son of Paleface."

In the latter, one of the "stars" was a Palomino horse named--you guessed it--"Trigger".  Astride him in "Paleface", and in many other movies, was none other than Roy Rogers.  
Because he and his cinematic (and real-life) partner Dale Evans so often appeared with their equine companion, it's not easy to imagine either of them riding anything else. But, apparently, they did, every now and again, trade their spurs for pedals and hooves for wheels:
