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.

HP-Turbo: A "Lost" Brake From Weinmann?

If you bought a new ten-speed bike of better-than-marginal quality during the '70's Bike Boom, there's a good chance that it came with Weinmann brakes and/or rims.

Most made-in-Chicago Schwinn bikes had one or both until about the mid-1980s.  So did many European bikes, if they didn't have Mafac brakes or Rigida rims.

Nobody ever got really excited about most Weinmann products:  They weren't flashy, but they usually did their jobs and their prices were reasonable.  The best example of this was their "Vainqueur" center-pull brake, which came on everything from the Schwinn Paramount (the touring model) and Raleigh International to the Schwinn Continental and Raleigh Grand Prix.  It was even found on some bikes from French constructeurs and English bespoke builders, who would attach the brakes to brazed-on bosses.

Probably the one product the company produced that was noticeably different from its competitors was their concave rim.  Its unique shape was said to give it superior strength to other rims.  I don't know whether the shape had anything to do with it, but I know (because I used to commute on a pair) it was strong--and noticeably heavier than other alloy rims.

In the late 1970s, Weinmann tried to modernize its offerings.  That is when they brought out the concave rim.  Around that time, they also introduced their "Carrera" brake, meant to compete with Campagnolo.  The quality was excellent and the finish beautiful.  However, it lacked the flats on the center bolt that allowed the brakes to be centered with a hub cone wrench (a nice Campy feature adopted by other brake-makers). Their quick-release device, apart from its finish, was no different from the one on the less expensive models. It had only "open" and "closed" position, while Campy's could be opened or closed partway to allow for wheels that developed wobbles.  

Another attempt to appeal to appeal to the ultra-high-performance (or simply rich and fashionable) market resulted in their version of the "Delta" brake--which, as "Retrogrouch" and others have suggested, may have been made for them by Modolo.  I never used Weinmann's or Campagnolo's Delta brakes, so I won't argue about the effectiveness, or lack thereof, some users claimed. There is no denying, however, that Campy's version may well be the most beautiful brake ever made.  Weinmann's had a more high-tech (for the time, anyway) look, and was available in black as well as silver.

A few years later, Weinmann came up with another interesting and unique brake:




The HP-Turbo was introduced in 1984.   I could find little information about it (I discovered it in an eBay listing), so I don't know how long it was produced.  I also couldn't find testimony from users, so I have no idea of how effective, or not, it may have been.

From what I can see, it's a centerpull brake with the straddle wire coiled around cams to which the brake shoes are attached.  I am guessing that the cams push those shoes into the rims, and that the arrangement is intended to somehow magnify braking power or modulation by increasing the mechanical advantage.

As I said, I am only guessing:  I may have been a mechanic, but I have never been a mechanical engineer.  For all I know, the brake might have been a revolutionary idea for which the cycling public wasn't ready.  Or, perhaps, some people tried it and found that it was complicated and, perhaps, the cams or other parts of the mechanism clogged with dirt or gunked up with grease. (They don't look very well-protected.)  Maybe it cost as much as a good sidepull brake, which came on about 90 percent of new bikes at that time, or cantilevers, which came on most of the rest of new bikes.   Or people thought it was just too ugly to put on their nice bikes.

Whatever its fate, I am curious about it.

Why Aren't You Paying Attention To The Tour de France?

Funny he should mention it:  The Tour de France is in progress.  

Yesterday, "Retrogrouch" said he is "barely" following this year's race.  I could say the same thing.  In fact, other cyclists I know who've followed Tours (and Giros and Vueltas) past say that they're paying little or no attention to the latest editions of these contests.


It got me to wondering why this is so, and whether it's just an American phenomenon.  Could Europeans' interest in those races also be waning?


Now, to be fair, the Euro football (soccer) championship ended three days ago.  It's held every four years, like the Olympics, and this year's version was held in France.  As it happens, les bleus made it to the championship game, which they lost to the Portuguese side.


Then again, the tournament was held in France in 1984 and 2000, both of which the French won.  This year's final matchup brought Cristiano Ronaldo-- who some regard as the world's best player-- and Antoine Greizmann--who could become his successor, according to some experts--onto the pitch as opponents.  So, even those football fans who aren't French or Portuguese (or simply fans of those teams) could find something interesting to watch.  Also, there was the "feel good" story about the Icelandic squad, which made it all the way to the quarterfinals against France (and, along the way, beat England).  This is especially shocking when you realize that more people live on Staten Island than in Iceland, where there are no professional leagues!


Stories like those keep casual fans interested in major sporting events.   Such drama seems to be lacking in this year's Tour.  There are favorites and "dark horses", to be sure.  But there aren't the sort of compelling rivalries, in part there is no rider-of-his-generation like Bernard Hinault and, thus, no one who's in a position to ascend to the throne, if you will.   There is also not a "feel good" story like the pre-fall-from-grace Lance Armstrong's (though, even in his heyday, there were whispers that he was doping).  





And, let's face it, there's nationalism in sports.  It's no longer startling to see British riders dominate the race, just it was no longer a shock to see Americans win after Greg LeMond.  While there are some very good riders from the former Soviet Bloc countries, none of them yet poses a challenge to the established order.  One reason, I think, is that those riders tend to dominate in sprints, often at the expense of other events, just as the best British riders--until about fifteen years ago--were time trialists.  Even Peter Sagan doesn't look ready to make the "breakthrough", and even if it did, it wouldn't excite fans in the US or the major cycling nations of Western Europe.

Finally, I think some people have given up, or are giving up, on cycling because of the widespread doping.  While football and other sports have their share of "juicers", the problem doesn't seem anywhere near as rampant.  At least, that's how fans seem to see it.


Anyway, if you want to read about a really exciting Tour, Retrogrouch wrote a very nice account of the 1986 version, which had everything this year's edition seems to lack.

The Cosmos, By Zeus

Last year, "The Retrogrouch" wrote an excellent article about the Basque component (and bicycle) maker Zeus, which was based in Spain.  They began manufacturing in 1926--a decade before Campagnolo--and seem to have continued until the late 1980s, or possibly the early 1990s.

Zeus is interesting for a number of reasons. One is they made almost everything on their bicycles:  Apparently, only the tires, tubes and spokes were not made by them, or one of their subsidiaries.  Perhaps only Raleigh, at least before the Bike Boom and on their three-speed models, manufactured as much as, or more of, their bikes than Zeus did. ("Schwinn-Approved" components were made by other manufacturers, e.g., Weinmann and Dia-Compe brakes, and Huret and Shimano derailleurs.)

Another reason why Zeus is worth looking at is that, while they developed a reputation for copying the designs of other manufacturers, they added their own touches and enhancements.  For example, their centerpull brakes were patterned after Weinmanns but were made with tighter clearances, tire guides (like the ones found on high-end sidepull brakes of the time), recessed allen bolts in the pivots--and a nicer finish.  And other components, such as the cranksets and derailleurs, used their Campagnolo counterparts as their starting points but departed in some details that didn't change their function but gave them character--and, often, made them lighter.  And perhaps no components more conspicuously exemplified the "drillium" trend of the 1970s than the "2000" line of components.

The funny thing is that the more Zeus came up with their own designs --they accumulated over 100 patents in their history-- the more they were criticized as "Campy copies".  Or so it seemed.

Even more ironically, those who made such criticisms probably never saw the Zeus part that was, perhaps, the nearest clone of the Campagnolo part that inspired it.  Actually, most of those critics didn't even realize the part in question--and others of the "gruppo" of which it was a part-- were made by Zeus because they were sold under the name "Alfa".

(The Spanish language doesn't have "ph" and "gh" diagraphs, as we have in English.  That is why it's spelled "Alfa", not "Alpha".)

Now tell me this "Alfa" derailleur doesn't look like the first version of the Campagnolo Valentino Extra:



Zeus Alfa


Campagnolo Valentino extra, first version

About the only visible differences between the two are the toothed pulleys on the Alfa, and the finish on the pivot bolts and adjustment screws of each one (black on the Alfa, chrome on the Valentino).  I never tried the Alfa, but I imagine that it doesn't shift much, if at all, differently from the Valentino--which was unexceptional, even for its time.

At the end of my first paragraph, I said that Zeus seemed to have continued until the late '80's or early '90's.  I could not find any information on when they succumbed (If Nietzsche were Greek, would he have declared that Zeus is dead?), but I had long thought that it was in the early or mid-80s, not long after they produced the 2000 series, their most renowned components.  Yet, while trolling eBay, I came across this:



European derailleur makers began to copy Shimano and SunTour designs during the early and mid-1980s, when those Japanese companies' patents started to expire.  Now, for all I know, Zeus may have made the "Cosmos" derailleur before that, as Spain was notorious for its lax patent laws.  Then again, it may have been made for them by someone else, although Zeus wasn't known for contracting other manufacturers.

Whatever the case, I never saw a "Cosmos" derailleur before.  Perhaps they were not produced for very long, or were not exported to the US.  If nothing else, it--ironically enough--belies the stereotype of Zeus as a "Campy copier".

Does Something Like This Turn You Into A "Retrogrouch"?

In just about every human endeavor, there are those who have to be the first on their block to have the newest and latest, and others who--whether they quote it or not--seem to be guided by Ecclesiastes:  "There is nothing new under the sun."

I guess I fall mostly, but not wholly, into the latter camp.  I ride steel frames, but I use threadless headsets and sealed-bearing hubs and bottom brackets.  And, while I ride dual pivot brakes and modern cassette hubs, I perch myself on Brooks saddles and slide, not snap, into my pedals.

I used to live with the hope that some completely ridiculous ideas that used to surface every decade or two would finally die off.  Alas, I have given up such hope that I will never see an electronic shifting system again.

I have even less reason for such hope after reading about a "smart bike" prototype Samsung has developed:



Now, a curved frame that would absorb the impact of potholes and such, I can understand, even if I wouldn't ride it myself.  But a rearview camera and a smartphone on the front?  And what do they mean by "laser beams that create an individual bike lane"?  That's a bad translation, I hope.

I have to admit, though, that I wouldn't mind seeing one of those bikes in person.  Still, I wonder what would happen if everyone rode one and had his or her individual bike lane.

The bike looks like it has a Brooks B-66 or -67 saddle.  I guess it can't be all bad.

Which Mercian Should He Ride Today?

It wouldn't surprise you too much to know that one of the blogs on my reading list is Mercian Cycles'.

People are amazed when they find out that I have four Mercians.  My usual response usually goes something like, "I'm the luckiest girl in the world."

(All right, now you know where my priorities lie!)

I figured that there are other people who have more Mercians than I do, but I don't know any personally.  I'd like to meet them--or look at their collection, anyway!

One such person--or, more appropriately, his bikes--are the subject of today's post on the Mercian Cycles blog.

A fellow named Kyle--who goes by the nom de blog "Retrogrouch"--has just restored a 1980 Strada Speciale with period-correct parts, including a first-generation SunTour Cyclone derailleur, Simplex retrofriction levers, milled Sugino Mighty cranks with "drillium" chainrings and Campagnolo Nuovo Tipo hubs.  This Strada Speciale, he says, is his eighth Mercian.

His collection includes vintage as well as modern models--and a modern bike with vintage Campagnolo parts that looks like a vintage bike.  They're all lovely bikes, so it's hard to decide which I liked best.

If you've been following my blog, though, you can probably understand why I like his 2008 Strada Speciale track bike:



or his 2012 Vincitore, built as an urban/path bike:



or, for that matter, his second Mercian, a 1979 "Classic":



I'd love to know how Kyle decides which bike to ride.
