If You Can See The Difference....

One of my favorite bloggers is The Retrogrouch.  So, I intend no disrespect to him with this post.

He is, of course, not the only cyclist to refer to himself as a Retrogrouch.  I am mainly in sympathy with him and the others who so identify themselves:  I ride steel frames, hand-laced wheels, downtube shifters (on my geared bikes), pedals with toe clips and Brooks saddles (except on my LeTour).  And all of my cranksets have square tapered axles.

On the other hand, I ride cassette hubs on my geared bikes (though the Trek 412 I'm building will have a screw-on freewheel).  The chief reasons are convenience and availablity:  No high-quality multiple-sprocket freewheels are made today (All of the good ones are single-speed.)  and most of the new-old-stock freewheels one can find on eBay and in other places have gear ratios that are useless to me.  (I am "of a certain age" and don't race, so what can I do with a 12-13-14-15-16-17-18?)  The unusued ones command exorbitant prices, while buying a used one is risky:  Your chain may or may not play nice with it.

And, as you can see from the photos in my sidebars, some of my components are black.   Some see that as a sign of a "sell-out", but there were indeed black components in the '70's and earlier.   Even the high priests of "shiny silver" at Velo Orange (which is actually one of my favorite online retailers) concede as much.

So, having said my piece about Retrogrouches, I want to introduce another species or clan or tribe (depending on your point of view) of cyclists.  I will call them Retrogeeks.  

Now, Retrogeeks and Retrogrouches are not mutually exclusive.  In fact, many can be identified, and would identify themselves, by both monikers.  One notable exception would be the late, great Sheldon Brown:  His encyclopaedic knowledge of all things bicycle made him a Retrogeek but, although he rode mainly steel frames and many older components, he did not think old is always better than new.  So he is not a Retrogrouch, though some have called him that.

One hallmark of a Retrogeek is that he or she knows authentic vintage bikes and parts from ersatz ones, and can tell whether or not an old bike or part was modified. Today, I am going to conduct a sort of Rorsach test that might help you to begin to figure out whether or not you are a Retrogeek.  Take a look at this photo:





Now take a look at this:





They are both images of the old Zefal Competition pump.  With its color scheme, you probably wouldn't be surprised to know that many pro and semi-professional French bikes of the '60's and '70's came with it.  The only other portable bike pump that was considered its equal (or, in some eyes, its better) was the Silca Impero.





What is the difference between the two Competitions in the first two photos?






If you look at the first two photos in this post, you will see that the pump in the second has the traditional press-on valve fitting, like the ones available for Silca pumps. To my knowledge, all Competitions came with it.  The pump in the first photo, in contrast, has a thumb-lock fitting--from a Zefal HP pump, the Competition's successor.





Pity that poor HP.  Had it been functional, I probably would use it on the Trek 412 I'm putting together:  It was the pump of choice at the time the bike was made.  Apart from the finish (polished on the Competition, silver anodized on the HP) and the color scheme, the only difference between the Competition and HP is in the head.

One nice thing about the Silcas is that you can change the head simply by twisting it off.  A Zefal head, on the other hand, attaches to one of the strangest-looking screws ever made










all the way inside the body.  Zefal used to make a tool for the purpose.  The only one I ever saw (or used before today) resided on Frank's toolbench in Highland Park (NJ) Cyclery, where I worked.


From Yellow Jersey


A screwdriver with a long flat blade would unscrew it--as long as the shaft is about 400mm long. (At least, I think that's how long the Zefal tool was.)  My longest screwdriver is only 12 inches (about 300mm).  So I resorted to another implement





or, I should say, collection of implements.  Assembled, it makes me think more of a crane--or of something made with an Erector Set-- than of any other hand tool I have ever seen or used.  




It consists of a 3/8" socket drive with two extensions--  one of 10 inches (250mm), the other 6 inches (150mm), a 3/8"-to-1/4" adapter and the blade assembly from one of my reversible screwdrivers which--wonder of wonders!--fit into the 1/4" socket.




Getting the screw out wasn't difficult.  But reassembling was a bit trickier.  I dropped the screw into the pump shaft and jiggled it until the threads protruded from the bottom.  Then I inserted my contraption and held it against the screw and screwed the head on for a couple of threads.  You can't screw it on all the way since the hole at the bottom of the pump has a hexagonal shape, into which the inner lip of the pump end fits.  

So, after threading the head onto the screw for a couple of threads, I rotated the pump body until the hexagonal lip of the pump head skid slid into the hexagonal hole at the bottom of the pump body (easily yet snugly:  the parts were well-machined). Of course, I lightly greased the hexagonal parts and the screw threads before re-assembling everything--and, between disassembly and reassembly, I cleaned out the shaft and gave the inside a light coating of fresh grease.

The "operation" was a success:  I pumped two tires to full pressure (90 PSI).  Yes, I cleaned out the head before I re-assembled the pump.

I know I could have kept the Competition as it was.  I ride only Presta valves, so the press-on fitting would have worked just fine. (I know:  I used both Silcas and Zefal Competitions for years.)  But it is easier to pump high-pressure tires with the thumb-lock attachment.  Plus, I now have a pump that nobody (or, at least, hardly anybody) else has.  Don't worry:  I saved the original Competition head and screw, just in case I decide to convert it back.

Now, if you've been following this blog for the past few weeks, you can guess which bike is getting this pump.

THE Tape Wasn't Number 1: A Pump Was. Or It Claimed To Be, Anyway!

Shopping online is like going to swap meets:  You find all sorts of things you never thought you'd see again.  That can be reassuring, especially if you remember something you used decades ago but have not encountered since and no one else seems to remember.  At least you can reassure yourself that your mind isn't doing the things you feared it would do when you got old--or that you're not having a flashback of something you first encountered in a haze of cannabis or the mists of Jack Daniels.

Last week, while surfing eBay, I found (and bought) a bike part that hasn't been made in decades, in its original packaging, for a reasonable price.  It's one of those things I might use if I actually go ahead with a project I'm contemplating.  If I find that I have too little time or disposable income--or simply feel too lazy--to carry out that project, I will probably hold on to that part I bought:  I might have use for it later. (Really!)  Also, it's something I used and liked in my youth, and the quality of it is very good.

When I decided to buy that part, I looked at the seller's website to see whether or not he had anything I wanted or needed.  Nothing else in his inventory (from a bike shop that closed down) fits either category, at least right now. But I did see something that brought back a memory or two:




In Philadelphia, there was a company called Skethea.  I don't know whether they aspired to be another Cannondale or Rhode Gear.  They seem to have made (or, at least marketed) only two products.  Both of them had names that proclaimed their superiority.  One of them is, the tape (or THE Tape) in the photo above.

Now, if you were around in the '70's, you might recall (if you can recall anything ;-)) that suede was very popular.  At least, stuff that looked like suede was en vogue.  Most things that purported to be suede weren't.  One example is a coat I had, which was made of cloth with a nappy finish.  Another is THE Tape.




I bought a set of it, in blue (of course!), to replace the plastic tape I shredded on my Nishiki International. I saw the same tape, in red, on another bike and thought it would look--and, I hoped, feel--good on my handlebars.

THE Tape was just a vinyl wrap, thicker than most, with a suede-like finish.  It could be had in a number of different colors, including two other shades of blue (Mine was a cobalt-ish hue.) as well as other shades of red and green, a few other colors and, of course, white and black.  As I recall, it didn't cost much more than plastic or even cloth tape.  And, because it was stretchy, it was easy to wrap.




If you've ever ridden a suede saddle, you know that, at first, it's more difficult to slide forward or back, as you might when you change hand positions on your handlebar, on it than on a seat with a smooth finish.  Likewise, it was a little more difficult to change hand positions (for example, to slide up or down the "hook" of the bar when climbing or descending) on THE Tape than it was on smooth or textured vinyl, or even cloth, tape.  




That little bit of extra force I needed to slide my hands along the bars revealed another flaw of THE Tape:  It had no adhesive backing, so the tape shifted and revealed gaps of bare metal.  The good news was that the lack of adhesive made it easier to un- and re-wrap.  The bad news:  The extra force needed to slide up and down on the bars made the tape stretch and, eventually, break.  

And normal use wore the nappy finish away.  So, after a few months you were left with "bald" discolored tape that soon disintegrated.  And, oh, yeah, it didn't look as nice as it did when you applied it.

I am aware of one other product made by Skethea, the company that manufactured THE Tape.  The Number 1 Pump (Yes, that was its name!) came out at around the same time as THE Tape:  about a year or two after Zefal introduced its HP Pump.  You still see lots of those Zefals in use today. But, unless you are around my age, you've probably never seen a Number 1 Pump.  I saw a few "back in the day", but I never owned one myself.

It was, I believe, an attempt to combine the best features of the Zefal HP  and Silca Impero pump.  So it had a thumb-lock valve that could be converted between Presta and Schraeder, and a mechanism that enabled the pump to bring high-pressure tires up to full pressure.  The Zefal had those qualities but was heavier than the Silca and required a clip.  The Number 1 Pump, therefore, put--or tried to put--the best Zefal HP features into a plastic body, like Silca's, that fit on the frame without a clip.

In an apparent attempt to distinguish it visually from the Zefal HP, Silca Impero and any other pump, the Number 1 had a clear plastic body.  Yes, you read that right.  So, you could see all those wonderful inner workings that the clever folks at Skethea dreamed up.  


Image result for see-through watches



I once had a watch like that.  For a while, thought it was pretty cool to see all those gears and pinions at work.  But after a while, the novelty wore off and I admitted to myself that watches with opaque faces and numerals in contrasting colors were much easier to read.  I stopped wearing the see-through watch, and I think I left it behind in a move.

But at least that watch held up to downpours I encountered while cycling and hiking, as well as some other forces of nature and my own recklessness and stupidity. So have my Zefal pumps.   I don't think the Number 1 Pump would have survived such things.  For that matter, I don't think the Number 1 Pump survived much of anything:  Within a couple of years of its introduction, it seems to have disappeared.  

I wish I could find a photo of that pump--or any information about Skethea.  They seem to have been one of those many small bike-accessories companies that sprang up in the US during the Bike Boom.  Cannondale is one of the few that have survived though, like most other manufacturers, they are making their bags (as well as their bikes) abroad.  A few other companies made it to the '80s and beyond; apparently, Skethea was not one of them.  A 1980 Bike Warehouse (now Bike Nashbar) catalogue lists The Tape; I can find no later reference to it.

If I ever find an image of a Number 1 Pump--or information about what happened to Skethea--I will post it.
