In Living Color



Black-anodized components, as I mentioned in yesterday’s post, have waxed and waned in popularity during (and before) the four decades I’ve been a cyclist. I hope I did not convey the impression that all components were black or silver.  At various times during my years on two wheels—and throughout the history of cycling—bike parts have been anodized in a spectrum of colors. 

Today, most of the parts available in a rainbow of hues are intended for fixed gear or single speed bikes.  While cranks, chainrings, pedals, cogs and even chains are available the Roy G. Biv range for bikes designed for the velodrome or urban hipsters.  But cranksets with more than one chainring, derailleurs, brakes and other parts made for road, touring or mountain bikes are usually made in either silver or black, with the latter shade becoming more dominant as carbon-fiber bikes gain popularity.  One of the few notable exceptions to the hegemony (or tyranny, depending on how you look at it) of silver and black in road and off-road bike parts is Velocity rims.

Weinmann Vainqueur 999 brakes.  Red and blue were offered only from 1961 to 1964.


However, in decades past, parts for road, touring and sport bikes have been finished in other colors, red and blue being the most common.  Weinmann and Mafac made their center-pull brakes in those colors for brief periods during the late 1950’s and early 1960’s.  Mafac, in their last years (the early 1980’s), also made their cantilever brakes in a variety of colors.

Modolo Professional brake, circa 1983.  And you thought white components were sooo 2009?


Ofmega Maglia Rosa rear derailleur.  You can't make this stuff up!


The component makers that became most noted for their color palettes were Italian and offered the greatest variety during from the late 1970’s until the mid 1980’s.  Perhaps the most prominent of them were Modolo and Ofmega.  The former finished their “Professional” brakes—found on otherwise all-Campagnolo bikes—in red, blue, green, gold and white, as well as the traditional black or silver.  The latter company finished their derailleurs, which were essentially Campagnolo Records rendered in plastic, in the rosa hue of the Giro d’Italia leader’s jersey as well as the jaune of its Tour de France counterpart, and just about every other color imaginable.

Colnago C60 with 24 karat gold-plated Campagnolo parts


Other companies did not offer such a wide range of tones but nonetheless parted, at least to one degree or another, from the silver/black binary.  I have ridden gold-anodized Mafac 2002 and Galli brakes; Zeus, Sugino and SunTour also made derailleurs, cranksets and other parts with gold anodizing.  Of course, if really wanted bling, you went for the gold-plated (24 karat) parts Campagnolo briefly made before the price of the precious metal skyrocketed around 1980.

Galli rear derailleur in "midnight blue"


In addition to gold, Galli offered one of the most distinctive finishes in the history of bicycle componentry:  “midnight blue”.  It was, of course, darker than most other blue parts but was more complex and richer than navy or black.  In addition to brakes, derailleurs, cranksets, hubs and other traditional “gruppo” parts, Galli offered rims (made for them by FIR) and retrofriction shift levers (manufactured by Simplex) in midnight blue.  Galli were even finishing 3TTT stems, bars and seatposts in their trademark finish.  Such an ensemble looked absolutely fabulous on a white Olmo of that period, but it also looked great on celeste Bianchis and just about any silver bike.

Kooka crank, circa 1992


Probably the last time components made for bikes with more than one gear or to be ridden by anyone besides Keirin racers or hipsters was the early- to mid-1990’s, when it seemed that every twenty-something in California whose father had a lathe in his garage was making parts, mainly for mountain bikes, that were lighter and more expensive than everything else on the market.  Kooka and Topline crankset, which I mentioned in an earlier post, are examples of that genre.  Interestingly, survivors of that time, like Paul Components and White Industries, are now making their (admittedly fine) stuff in silver and black.  Chris King may be the only exception:  His headsets, hubs and other parts are finished in even more colors than they were two decades ago.

These days, all of my bike components are black or silver.  Part of the reason is that most of the stuff I use is available only in those colors.  But another is that I don’t want parts that detract from the kinds of finishes I like on my frames.

"The First Brakes That Worked"

If you have a Peugeot--or almost any other French bike (Motobecane being one of the notable exceptions) made before the late 1970's, you are riding them.

No, I'm not referring to those plastic Simplex derailleurs or the longer-lasting but worse-shifting Huret models.  Unless you acquired a bike that was never ridden, you've probably had to replace your shifters by now.  Even If you didn't need to, you might have.




On the other hand, there's a good chance you're still riding your Mafac "Racer" brakes.  You might have replaced the pads and cables--actually, you should have because even if the bike wasn't ridden, the cables were probably corroded and the pads hardened.  If you did, and your brakes are adjusted, they work as well as--or even better than--most brakes available today.

I am mentioning them because, for about two decades, they achieved a distinction very few other bike parts held:  They were used on bikes at all price and quality levels, from the machines ridden by Tour de France winners to the most utilitarian city and town bikes.  Some time in the mid-1970's, Mafac came out with the "Competition", which was really the same brake with a shorter reach.  Later, it was cleaned up and polished (and still later offered with gold anodizing).  A longer version of the Competition --i.e., one with the same reach as the Racer--was also marketed.

 

The one other difference between the "Racer" and "Competition" was the straddle cable:  The one on the Competition had double ball ends, while the Racer used what was essentially a shorter link of derailleur cable (with the barrel-shaped end used on Campagnolo and Simplex shifters) bolted into hex-shaped ends.

While some may see these brakes as anachronisms, they have an important place in cycling history. Some cycling historians say they were "the first brakes that actually worked".  That is almost not hyperbole:  There seemed to be a mentality among brake-makers (at least those that made brakes for road bikes) that was expressed by a Campagnolo representative at a training session:  The purpose of the brake is not to stop, but to decelerate.  Some would argue that notion gave the brakes of the time too much credit.

(When I first got serious about cycling, there was a joke that the Universal 68 side-pull--commonly supplied on bikes that were otherwise all-Campagnolo--was a "courtesy" brake.)

One reason for Mafac's superior power was the way the brake block attached to the arm:  through an eyebolt.  This allowed a far greater range of adjustability along the vertical and horizontal planes.  This was particularly important with rims like the Constrictor Asp, which did not have flat parallel sides.

(The Asp seems almost like an embryonic version of today's V-shaped "aero" rims!)

Another advantage offered by the "Racer" brakes was that the length of the straddle cable could be adjusted to optimize the mechanical advantage of the brake.  This allowed the brakes to work well with a variety of different levers, as well as with the pads set all the way up or all the way down--or anywhere in between--on the brake arm.

Now, you might be thinking that the first working center pull--and the one on which others were based, at least in part--is not so important because sidepulls have advanced so much, and so Mafac has been relegated to la poubelle de l'histoireWell, even though Mafac hasn't been in business for about three decades, their place in cycling history is sure because of the very first product they made, about seven years before the "Racer" was introduced.



Their cantilever brake, introduced in 1946, remained in production throughout the company's history (about four decades).  It's not the first of its type.  But, compared to the ones that had been made before, it was easy to set up and use, and was more powerful.  For as long as Mafac made them, nearly every lightweight tandem was equipped with them.  So were many high-quality bikes made for fully-loaded touring, and most cyclo-cross racers.  For the latter, cyclists often brazed the necessary posts to old racing frames to accommodate the cantilevers which, in addition to offering superior stopping power, were not as easily clogged by the mud that is an essential element of any cyclo-cross race.

The early mountain bikes also used Mafac cantis.  When Dia-Compe and Shimano made  cantilever brakes that appeared on off-the-shelf touring bikes (and second-generation mountain bikes) sold in the US, their designs were basically adaptations and refinements of Mafac's.  Weinmann also more-or-less copied Mafac cantis and, apparently, bought Mafac's tooling and continued making cantis, in steel as well as alloy, until their own demise in the 1990's.

Many of us still use cantis today.  Those of you who use V-brakes also have to thank Mafac, because Vees were developed from cantis.  And even those of us who use dual-pivot sidepulls owe a debt of gratitude to Manufacture Auvergnoise de Freins et Accessories pour Cycle for developing the centerpull that helped to make it possible!

For me, it's interesting to recall that Frank Chrinko, the proprietor of Highland Park (NJ) Cyclery when I was working there, would not ride any brakes but Mafac centerpulls.  In fact, he put a set of Competitions, along with a mixture of Campagnolo and top-shelf French and Japanese parts, on a frame that was built custom for him.
