In My O-Pinion, This Could Be Interesting


Derailleurs are great.

Well, most of the time--for me, anyway.  With the exception of Tosca, my Mercian fixed-gear, my other "fun" bikes have derailleurs on them.  Cyclists have been using them for nearly a century; in that time, derailleur-equipped bikes have gone from having two cogs to eleven on the rear wheel.  (When I first became a dedicated cyclists, five in the rear was normal; six-speed freewheels were new and exotic

I think 8 rear gears is the "sweet spot" where a wide range of gear options intersects with relative durability and un-fussy shifting; 9 gears--which I use--sacrifices a bit of chain life but greater availability of cassettes across a wider selection of gear ratios and price ranges.

Aside from Tosca, I have one other derailleur-less bike:  my commuter/"beater", which has a single-speed freewheel.  Most commuters here in New York don't have to negotiate many, if any, hills.  I myself make one climb of any significance on my way to work in the Bronx.

Now,  if you don't have to ride hills or are very young or strong, a single-speed bike is a great option if you want to do as little maintenance as possible.  If you're really young and strong, or a messenger, (I was all of those.)you might even like a fixed-gear single-speed.  (At times, I have commuted on a fixed-gear and, as I've mentioned in other posts, I've been a messenger.)  But if you're not-so-young or athletic, live in a hilly area or simply want to sweat as little as possible, you might prefer a variable-gear bike.

If you want variable gears but don't want to use derailleur, you only other option--at least, if you live here in the US--is an internally-geared hub.  The most familiar kind is the classic three-speed.  Sturmey-Archer made several models, but by far the most popular (or at least common) was their AW, which came on the Raleigh, Dunelt, Robin Hood and other English bikes.  Shimano, Sachs and a few other companies also made them; the one marketed by SunTour during the 1960's and early '70'd has long been rumored to be a re-badged Sturmey-Archer.

The problems with those hubs are that they don't offer a wide variety of gears, the spacing between gears is less-than-optimal and, with the exception of the old (pre-1975 or thereabouts) Sturmey-Archer models, they tend to wear out quickly.  Moreover, they don't transmit power (turn your pedal strokes into wheel revolutions) very efficently and weigh significantly more than a hub with a cassette or freewheel combined with derailleurs.

Worst of all, if riders neglect (as most do) even the minimal maintenance internally-geared hubs require, they can fall  to the ravages of rain, wind and other elements almost as easily as the exposed parts of a derailleur.

For some time, European commuters and utility cyclists have had another option:  a gear box.  




The German-made Pinion gear box is a standard feature on about 90 different bike models sold in Europe.  It is a rarity in the US, but that could change:  The company is opening an office in Denver in conjunction with Gates, the manufacturer of the Carbon Drive System.

Think of Pinion as an internally-geared hub on your bottom bracket:  The box contains a set of epicyclic gears, like the ones inside the hub, in an oil bath.  But, unlike the hubs, which had oil caps on their shells, Pinion requires an oil change every 10000 km or so.  The good news is that Pinions appear to be more hermetically sealed than internally-geared hubs, so the lubrication is less prone to contamination and, one assumes, runs more smoothly.

The main downside to Pinion is, apart from its weight, the fact that it can be installed only on a Pinion-specific frame. For some, that limitation is counter-balanced by its greatly reduced maintenance, ease of shifting and the fact that it's available in a number of gear configurations, with 6,9,12 or 18 gears in a range from 295 to 636 percent.  This means a wider range of gears, with narrower steps in between, than is possible in an internally-geared hub.  It's also available with a die-cast magnesium gear box, which cuts the weight somewhat, in addition to standard aluminum model.

A Worker Rewards Hard Work--With A Bicycle

Perhaps you frequent a store or cafe and see the same person behind the counter every time.  Maybe you've progressed beyond exchanging pleasantries and have come to know something about that person who makes your coffee or sells you a newspaper or stamps.  

Yes, such things happen here in New York.  But I'm sure they happen even more frequently in some smaller towns.  


While it's nice to get to know that person who makes your sandwich, doing so can also be a little sad:  That person might be doing it because of some unfortunate circumstance.  And getting to that counter every day could be a job in itself.


Such was the case of Johnny Phillips.  Every day, he walked two hours to the Circle K market in Springfield, Illinois, where he worked a ten-hour shift.  Then he walked two hours to go home.


Jim Copeland learned of his story because he stops at that Circle K store every night, on his way to work.  He knew that Phillips "had to walk through a bad neighborhood" and figured that "if he did all that, he was really dedicated."  So, Copeland thought, "maybe I could help him."


On his way to work, an idea popped into Copeland's head:  "What if I could find a decent bike at a decent price?" So he went--where else?--to Craigslist, where he found a suitable machine. He took it to a "bike nut" friend, who oiled the chain and adjusted the brakes.


On Monday, Copeland brought the bike to the store's parking lot, told Phillips to close his eyes and handed him his new mode of transportation.  One can only imagine the emotions Phillips must have felt, some of which showed on his face.





For his part, Copeland drives a truck for a postal service contractor, so I suspect he knows a thing or two about work and dedication!

Some Of My Old Commuter/Beater Bikes



I am both delighted and amused that Bike Boom-era ten-speeds are en vogue, at least with certain (mostly young and urban) segments of the population. 


Go to Bushwick, Brooklyn or any other enclave of the young and self-consciously hip (and bohemian poor) and you’ll find flocks of vinage Fujis, packs of old Peugeots, ranks of stalwart Raleighs and gaggles of Gitanes and other classic names promenading through plazas or chained to railings.


One reason is, of course, that such bikes are—as long as they haven’t been crashed, submerged in a deluge or otherwise abused—as good now as they were then.  While nobody would try to race those bikes, most of which had mild steel frames and cottered cranks, they offer rides that are reasonably quick yet comfortable.  The frames geometry, while maligned by racers and other performance-oriented riders, make the bikes versatile in ways that few contemporary bikes are.  That is the reason why so many have been converted to single- and fixed-gear urban cruisers.



What that means, of course, is that such bikes sell—especially in New York and other urban areas—for far more than they did a few years ago.  Even so, it’s often less expensive to buy such a bike, convert it and add racks, baskets or whatever else one likes, than it is to buy a new “urban” or “Dutch” (really, some marketer’s idea of “Dutch”) bike.



However, I can recall a time when Bike-Boom era ten-speeds could be had for a song, or even less.  As I recall, that time commenced around the mid-‘80’s, when mountain bikes became the machines of choice for the few (at least here in the US) bicycle commuters and “ride around the park every other Sunday” cyclists of the time.  Most people who bought ten-speeds in the ‘70’s and early ‘80’s rode them only for a short time before relegating them to garages, basements, barns and other “out of sight, out of mind” sites.  Eventually, they’d be sold in garage or estate sales, or even given away.  Some people used them in trade-ins for mountain (or, later, hybrid) bikes, so old ten-speeds could be had for very little money even from bike shops.  



For years—about a decade and a half, in fact—I used such bikes for commuters and “beaters”.  When I could, I rode them “as is”—of course, after inflating the tires, lubing the chains and such.  Usually, I changed the saddle and one or two other parts, and added a rear rack and fenders if the bike didn’t already have them.  As parts (usually wheels) broke down or wore out, I replaced them, sometimes with parts I had on hand or friendly shops allowed me to scavenge.  My ability to build wheels came in handy, as I could get discontinued models of rims cheaply and re-use the hubs that came with the bike, or get inexpensive replacements.



From the mid-‘80’s to the mid-‘90’s, bike theft was (I believe) even more rampant than it is now.  That was a further incentive to use such bikes, as losing one wasn’t as much of a financial (or emotional) blow as losing one of my better bikes would have been.  On average, I would say that I would ride one of those bikes about a year before losing it to a thief.


None of my photographs included any with any of those bikes in it.  However, I can recall, fairly accurately, each of those bikes and when I rode it.  I will list them below:  The year or decade in parentheses is the time, as best as I could determine, the bike was manufactured.  The year(s) on the right side indicate when I used the bikes.
