"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.

Light Along The Way



I tend to remember scenes, places and situations by the feelings I associate with them.  Those sensations are very much influenced by the light around them.






Although yesterday’s ride took me through places I’ve cycled many times before, I think it will become a Fall Classic, if you will, in my memory.



The Verrazano-Narrows Bridge always does interesting things to the hues of water, sky, sun and clouds:




and to newly-denuded limbs exposed to the wind that stripped them so that they could only open themselves to late-day sunlight trapped in a cloud.



At the end of the day’s fading light, across the water, a boat



follows the setting sun



Is it headed for a fjord of fire?

Why Did The Fill-In-The-Blank Cross The Road--In My Path?



I’m still thinking about the cat that smacked into my front wheel and caused me to crash.  The bike and I are OK, but I wonder what happened to him/her.

Other cats have crossed my path as I’ve pedaled.  One or both of us get out of the other’s or each other’s way.  At least, that’s how it worked until that unfortunate feline

Dogs are different.  I’ve been chased by a few; others jumped and tugged their leashes.  Some have walked up to me when I’ve stopped, and I rescued one that was wandering around in the middle of an intersection not far from where I worked.  I carried her in one hand while I steered with the other.  She stayed remarkably calm as I pedaled through traffic.  If I didn’t already have two cats—for whom I had to plead with my landlady for permission to move them with me into the house in which I was living—and had a bigger living space, I might have kept that cute little Yorkie—at least, I think that’s what she was.

As for other animals, I think most can be placed in one of two categories:  the ones who do whatever they can to get out of our way and the ones that barrel ahead in a straight line, completely oblivious to any cyclist who might collide with them.

Deer are in that latter category.  Several have bounded across my path; a riding buddy and I came within a tire width (or so it seemed) of splattering ourselves against the side of one that darted across the road at the bottom of a steep hill we descended.  In Bucks County (PA), no less.  You can’t make this stuff up.

I’ve seen moose, ibexes and mountain goats act in the same way:  straight ahead, with blinders on, across the road.  I wonder whether all ungulates behave that way.

Animals that avoid you include cats (most of the time), squirrels, chipmunks, lizards, armadillos and, believe it or not, snakes.  At least, the three snakes that I can recall crossing the path I was riding slithered away. 

Every one of those animals I’ve mentioned has entered upon “my” (Talk about a sense of entitlement!) riding space as I approached. 

In Florida, I’ve ridden paths and roads that rimmed or transversed swamps.  I’ve seen alligators, but none came near the road or path.  Do they avoid those things altogether, or was I just lucky?



Why did the alligator cross the road?  Well, actually, this one didn’t cross:  It was just standing there, on a street in DUMBO as I rode by.  I can’t help but to wonder:  Did it somehow just end up on the street in that position, or did someone leave it there?
