A Hex On This Monark

It's easy to believe that all bikes made up to the early 1980's or so had round steel frame tubes that were 28.6 mm (about 1 1/8"), or thereabouts, in diameter.  When I first became a dedicated cyclist in the late stages of the '70's Bike Boom, about the only bikes that weren't made with such frame tubes were "Chopper"-style bikes with stays and other frame members made out of flat bar stock or thin twin-lateral tubes.

Turns out, though, that there have been all sorts of variations of tubing diameters and shapes since the "safety" bicycle first appeared late in the 19th Century.  Even before Cannondale and Klein started to make frames with oversized aluminum tubes, bike makers used larger-diameter tubes with thinner walls in an attempt to make bicycles stiffer and lighter.  The problem with them was that knowledge of metallurgy (Reynolds 531 and Columbus tubings weren't created until the 1930's) and welding or brazing wasn't as advanced as it is now.  So, frames built with large-diameter thin-wall tubing usually met early demises.

And frame tubes and stays did not start to deviate from having spherical cross-sections when mountain bikes and carbon-fiber frames reached the mass market during the 1980's and '90's.  There have been many variations on tubing shapes and configurations.  One of the most famous is, of course, the curly rear stays found on some vintage Hetchins frames.  (Sheldon Brown prized his.)  Other frame builders and bike makers experimented with tubes that were triangular or shaped in other ways in the name of aerodynamics.  Of course, what those makers and builders soon realized is that, in the end, a bike can't be more aerodynamic than the cyclist perched atop it. 

Then there were other variations that were made for no apparent reason.  I get the feeling that the companies and builders that employed them were trying to make their bikes look "distinctive".  In other words, they were probably little more than marketing gimmicks.  But, I'll admit that some of them looked pretty cool, like this 1947 Monark Silver King with hexagonal (!) frame tubes:

The shape, and the stripes on the head tube, give the front an odd sort of Art Deco look

and the appearance of raw industrial power at the bottom bracket.

Whatever you think of the frame tubes, how can you not love a bike with a rear fender reflector like this?

Now, if the frame looks like it was made of aluminum, there's a good reason:  It was.  That, of course, begs the question of how the headtube and bottom bracket were joined to those hex-shaped tubes.  

Well, they were neither welded nor brazed together.  Nor were they glued ("epoxied") like the ALAN frames of the 1970's or Vitus frames of the '80's and '90's.  Instead the tubes were "mushroom wedged" into the "lugs".  I have not found anything that describes how "mushroom wedging" is done.  I can only imagine.

As for the Monark brand:  They should not be confused with Monarch bicycles of the 1890s which share one characteristic with Monarks:  they were made in Chicago. (And you thought Schwinn was the only bike maker in the Windy City?)  Monark of Chicago also should not be confused with Monark of Sweden which, to this day, continues to build bikes as well as mopeds and other items.

Monark Silver King Inc., as the Chicago bike maker was officially known, started off as a battery manufacturer early in the 20th Century and began to make bikes under their own name, as well as for house brands of Montgomery Ward and Firestone, in 1934.  They made some of the most stylish and unique baloon-tired bikes of the 1940s and '50's.  

Apparently, they stopped making bicycles--ironically enough--during the early 1970s, when the Bike Boom in North America was picking up steam.  Rollfast, a manufacturer literally steps away from where the Twin Towers rose in New York, met a similar fate around the same time.  The Bike Boom translated into sales mainly for "lightweight" (i.e., ten-speed) bikes and all but destroyed the demand for balloon-tired and middleweight bicycles, the mainstays (or, in some cases, the entire production) of companies like Monark and Rollfast.

Quelle Coincidence!

Wouldn't you know it?  The other day I wrote, among other things, about aluminum frames of the recent and distant past.  So, on my way out of work last night, what should I chance to see but this?:




It is, of course, one of the most iconic aluminum frames of all:  the Vitus 979, from France.



Vitus aluminum frames were somewhat-more-refined versions of what is commonly regarded as the first modern aluminum frame:  the ALAN, from Italy.  (Alan is short for "alluminio anodizzato," Italian for "anodized aluminum.) 

While the ALAN consisted of aluminum alloy tubes bolted and bonded into thicker aluminum lugs, Vitus skipped the bolting and simply glued the frame together.  Company engineers claimed--with justification, I believe--that the bonding material Vitus used was stronger than what was found in Alan frames.  Whatever the case, I have never heard of either frame coming apart at the joints.

The ALAN was introduced in 1972; the Vitus came seven years later.  While the Italian frame gained a small if loyal following among time trialists and others who wanted to build the lightest possible bike, its French counterpart was ridden by club cyclists as well as racers.  Also, being one of the most expensive frames available at the time, it had a certain amount of snob appeal in the '80's, when it reached its peak of popularity.

Like the ALAN, the Vitus was often kitted out with the lightest or most "trick" componentry available.  For the ALAN, that meant Campagnolo Super Record gear with titanium bits.  On the other hand, Vituses were often seen with Mavic hubs and GEL-280 rims (Mavic had yet to produce a pre-built wheelset), Stronglight 106 cranks with the company's titanium bottom bracket, CLB or Speidel brakes and Huret Jubilee derailleurs.  



The Vitus set-up I described is what Jeannie Longo, whom many regard as the greatest female racer of all time, rode to victory in the Tour de France Feminin and her first Olympic win.  

The example I saw parked on the street looks like a model from around that time.  When new, the top and down tubes were anodized in a magenta-ish shade of pink, while the seat tube had more of a purplish hue.  Anodizing, especially in brighter and bolder colors, tends to fade over time; the bike in the photos doesn't have much of its original tint left.

When I see bikes like that--or a classic steel frame--I always wonder whether it's being ridden by the original owner, or whether it was inherited.  (A young man I met on the Staten Island Ferry about a year ago told me his father raced the Simoncini he was riding.)  In the case of the Vitus, or an Alan, I also wonder how much it was ridden over the years.  You see, those frames had aluminum tubes in the same diameter as Reynolds, Columbus or other steel tubes including the ones Vitus were still making at the time they produced their aluminum frames. That made for a very light, though flexy bike.  (On the other hand, it also made for a very comfortable ride over long distances and hours.)  Those factors probably explain why Longo and other female--as well as smaller male--racers rode them.

In 1992, Vitus superceded the 979 with a new model, the 992.  It featured ovoid aluminum tubes in an attempt to make the bike stiffer without resorting to large-diameter tubing, as Klein and Cannondale were employing.  Even so, the 992 was never as popular as the 979, in part because it came along just as titanium frames were becoming popular. And, of course, within a few years carbon--which Vitus helped to re-introduce during the 1980's--would take much of the market share enjoyed by tituanium and Vitus aluminum frames.

Still, whoever rides the bike I saw last night is enjoying an interesting bit of cycling history.  Somehow it's nice to know that Vitus is still making aluminum and carbon frames though, apparently, it's discontinued its maganese-molybdenum steel tubing.  However, I couldn't find information on whether or not the frames were still being made in France.  After all, Look and Time, the most venerable French carbon-fiber bikes, are now being manufactured in Asia.
