Future Shock Today

Someone--I forget who--once told me, "Anything you do in a car, you can do on a bicycle." 

My grandmother once told me, "Be careful of what you wish for; be careful of what you believe in."

Never did it occur to me that those two statements could actually converge.  Now I realize that it was bound to happen, given that I wished to believe the statement that opened this post.  If I do say so myself, that statement been true in my life:  I've never owned a car and have no wish to own one.

But I never realized just how true it could be until I came across this:



Who would have thought it possible to take the same obnoxiously loud stereo systems some young men have in their cars and transplant them onto bicycles?  The Future Shock Bike Crew, that's who.

The Crew consists of unofficial founder Nicholas Ragbir and his sister Jessica, and of Bhimraj brothers Anil and Travis.  They emigrated with their families from Trinidad and Tobago to the Richmond Hill neighborhood of Queens--about seven miles. or a quick run on Tosca, from my apartment.



I've actually seen them on the streets.  Unfortunately, I was on my way to or from work, or was weaving through traffic, so I have never had the chance to talk with or photograph them.  However, I recently found a page devoted to them on the Worldwide Cycling Atlas.

I wonder how long those young people keep on "pimpin' out" their bikes with stereo equipment and "peddling" their music through the neighborhood.  Their exploits involve DJ'ing and engineering as well as cycling.  Who knows:   They might develop whole new genres of cycling, entertainment or technology.  Whatever they do in the future, I hope it's as much fun for them as what they're doing now!

Sheldon, Aaron and Bob



Today was an unusually warm day for this time of year.  Because of a scheduling oddity, I didn't have classes today.  So, I took Tosca out for a ride through some of the landmarked areas of Woodside and Jackson Heights, as well as the promenade along that starts near LaGuardia Airport and goes to the World's Fair Marina.


Then I had an appointment in Manhattan, to which I rode Vera.  I changed bikes because I changed clothes:  from sweats and trainer shoes to a skirt, blouse and dressier shoes.


After my appointment, I took a quick swing down to Bicycle Habitat, from which I ordered Tosca, Arielle and Helene as well as some of the components I hung on them and other equipment I use with them.  Hal wasn't in, but I did see two employees I hadn't seen in a while:  Aaron and Sheldon.






Sheldon is an old riding buddy whom I didn't see for about a decade or so until I bumped into him in the shop not long before my surgery.  I don't think I'd seen him since some time in the fall:  I think I showed up on his off-days or -hours.


Aaron, like Sheldon, has been working in the shop for some time.  He doesn't want me to publish his photo. However, he said I could publish photos, and write about, of one of his bikes, of which I'd only heard before today.  




It's a nice Bob Jackson from, I believe, the '70's.  He's outfitted it with contemporary components: The only "period" pieces are the SunTour ratchet shifters and Cyclone rear derailleurs.  I can understand using those:  I used them myself, back in the day.


I remember, as a teenager, seeing Bob Jacksons, Mercians, Ron Coopers and the frames of some other English builder--I don't remember which, except that I don't think it was Jack Taylor--in a catalogue somewhere.  






I knew that the best racing bikes were believed to be those from Italy and a few American custom builders. The English made some excellent racing frames, too; in my heart of hearts, I really wanted one of those--or one from a French constructeur--even more than an Italian bike.  I would eventually ride, and race, on a couple of Italian bikes, but I really liked the ride qualities of those English frames (I got to try a few that belonged to customers in shops where I worked.).  Plus, the Italian racing frames always seemed gaudy to me, even in my youth; I always felt that my "bike for life" would have the meticulous lugwork and other detail of those English builders.  Their workmanship impressed me more than what I saw on the Italian bikes.




The only braze-ons the frame has are for the water bottle cage (on the downtube only) and a "stop" for the shift lever band.  That was typical on bikes of that time:  at least a couple of bikes I owned were so made.


That frame is at least thirty years old, and it's not hard to imagine Aaron--or somebody else--riding it for another thirty years.  I think Bob Jacksons are still being made--although, by this time, I rather doubt Bob Jackson himself is building them.  I don't know whether Ron Coopers or Jack Taylors are still being built:  I haven't seen references to them in recent catalogues or magazines.  At least it's nice to know that Mercian is still keeping up the flame they, and those other builders, kept burning for decades.

The Rise And Fall Of Rapid Rise

I forget who told me that there's no idea so bad that nobody will try to revive it.

Here's a case in point:  low-normal rear, and top-normal front, derailleurs. 

On the bikes most of you ride, pushing the right lever forward shifts you to a higher rear gear (top-normal), and pulling the lever brings you to a lower gear.  Conversely, pulling on the left lever shifts your chain to the larger front sprocket, and pushing it drops your chain to the smaller, or lower gear (low-normal).  The derailleurs I'm going to talk about do the exact opposite. 

It seems that every generation or so, someone tries to revive the idea.  Why, I don't know.


This is an early example of the genre:  the Simplex Champion de France, circa 1935.  Believe it or not, it was a technological marvel for its time, even though it couldn't handle much more than a 22 tooth rear cog and a difference of 8 between the largest and smallest cog. 

It is, I think, rather elegant:  In particular, the cage shape makes me think of a part of a piano rather than a bicycle.  However, the shifts of single-pulley derailleurs are inherently imprecise; low-normal operation only exacerbates the problem.

As one might expect, World War II halted derailleur development and all but stopped their manufacture altogether.  The 1950's would see new innovations and experiments, including the pull-chain mechanism (which Shimano briefly revived on its mountain bike derailleurs during the late 1990's) and, most important, a derailleur with a parallelogram mechanism rather than a single arm or cam.  However, Simplex and other companies also revived low-normal rear derailleurs.

To be fair, the first modern rear derailleur (and, some would say, the first that shifted well)--the Sun Tour Gran Prix of 1964--also was low-normal.  But within two years, Sun Tour abandoned that operating principle, realizing that the slant-parallelogram design (which is found on every derailleur of any quality made in the last quarter-century or so) did more to improve shifting than any other idea or innovation.

However, Sun Tour continued to make front derailleurs that were "top normal" well into the 1970's.  I had one such derailleur.  It shifted well enough until the spring started to lose its tension.  With a low-normal front derailleur, you can sometimes adjust the cable tension to make up for the lack of spring tension.  That's not an option with high-normal front derailleurs.

It's also not an option with low-normal rear derailluers.  I briefly rode one on my mountain bike about fifteen years ago:  a Shimano XTR.  Luckily for me, the shop from which I bought it allowed me to trade it in for a more conventional XT rear.  The owner of the shop reasoned that the amount of wear I put on the XTR made it depreciate enough to warrant an XT as a replacement.

I'd say that was an example of addition by subtraction:  I was happy with the XT, as I was with an earlier version of the same derailleur.  On the other hand, I never liked the low-normal XTR, which was one of the most expensive derailleurs made at the time.  It never had the firm, postive feel I like when shifting:  Even when the gear engaged smoothly and silently after a shift, it always felt as if the chain would slip or jump off the gear at any moment. 

Other cyclists with whom I rode--who included hard-core mountain bikers as well as roadies like me who went off-road for a change of pace--felt the same way about that derailleur. And, in looking back at some old magazines and books, it seems that every time low-normal derailleurs come out, the high-mileage and hard-driving riders don't like them.  Even less-experienced riders who thought they were the newest and latest thing soon soured on them.

I see that Shimano has given up on low-normal (or, in their lingo, "rapid rise") rear derailleurs, at least for now.  I wonder whether they, or any other company, will revive them.  Maybe they will in a decade or so, when there's a cohort of cyclists who didn't use rapid-rise and who don't heed this gem of wisdom from Ecclesiastes:  There is nothing new under the sun.
