Not that I have been neglecting my journalistic duties, it was just that I was away for a bit rediscovering my former, two-wheeled roots. See, before I was super-serious about my fitness, and discovered the wonderful world of road cycling, I was a big-time gearhead. Truth be told, I never thought I would give up motorcycles until the day I died. Having a motorcycle a full seven years before I bought my first car, motorcycles were in my blood.
Road cycling changed all of that. Not that I have turned my back on the combustible part of the two-wheeled realm, something just clicked the moment I clicked into my first set of clipless pedals. In addition to the fitness component, cycling was different in respects to cost, time, and the biggie, I could start having a ball right outside my front door. With motorcycling, and in particular, motorcycle racing, I had to travel at great time and expense just to get the fun started.
Nothing beats the sights and sounds of a Honda CB160 race. Shot location: Turn 4, twenty-eight years after the author dragged a knee through there in the photo atop the article.
Libraries are full of books related to the Human
Condition.I mean volumes and volumes of
manuscripts have been written, and hundreds-of-thousands of people have earned
PhD’s attempting to explain how the human brain works and how we communicate,
relate, and value each other.
Well, without all of the aforementioned scholarly orgasms, I
am proud to announce I can sum up how humans relate, and more to the point, how
Motorists relate to Cyclists in three, simple, direct words: “Get a life!”
Yes, this was the lesson I learned today, courtesy of a mid-40’s
woman as she crept up behind me at a signal in her old-beater car, honked the
horn, and then squeezed her way between myself and the car in the left
When I expressed that I legally held the lane, with an
additional, firm, verbal concern for my safety (while pointing out her obvious
rudeness), that was when the Philosopher-Behind-the-Wheel laid on me those
three, little words, and showcased how motorists relate to cyclists for having the
nerve to share the roads with them.
All I did was impart to her the legalities of the situation,
and ended my part of the conversation with a “Please drive safely.”I find it is easier to be armed with the
facts than insults.People don’t like
facts, which usually leads to insults – From them, not from me.
In totality, while it is obvious this motorist’s behavior is
not the mainstream, just remember this – It only takes one of her kind to end
Editors Note:Following the recent article on Carbon Fiber Wheels
(Cycling Dynamics, 04/18/2013), here is a more in-depth look at this wonder material.
Composites are pretty cool things.In the most basic definition, a composite is when
two or more materials are combined together to make a new, unique, and stronger
material.Therefore, something as simple
as concrete, or as complex as carbon fiber, are both classified as composites.In between are a world of materials such as fiber
glass and plastics, however, the subject of our study will be carbon fiber.
Carbon composites can be formed into just about anything one
desires, from prosthetics, to wheelchairs, to cars, to satellites, to whole
airplanes (yes, they do), plus bicycles and their associated components.Carbon structures are light, strong, can
withstand ridiculous temperature variations, positive and negative atmospheres,
are moisture impervious, non-conductive, low maintenance, and have a relatively
long life.A wonder material?You bet.However, like all things in this life, carbon does have its limitations.Carbon composite structures do not take
certain stress loads very well, especially blunt impacts.
Raw Carbon Fiber Weave
So just what is Carbon Fiber?In its most basic form, it is strands (or
threads) of carbon which are then weaved into a cloth.Depending on the intended use, the cloth is
woven into different weight weaves, and it is here that the finished product
gains its grade, strength and expense.On
its own, it is strong in tension (though easy to cut laterally), and it is very
flexible.Think of a blanket, and you
get the idea of the properties of carbon cloth.Add a resin, and in most cases, some heat and pressure, and the whole
picture changes dramatically (as can the shapes).
Carbon Monocoque Lola
And now for a very important distinction - The carbon fiber in
your bicycle is not the same as the carbon fiber in a race car, nor
is it the same carbon fiber used in a Boeing 787 commercial airliner.The blanket term carbon fiber needs to be
used very carefully, as it encompasses all similar composites (such as Carbon
Graphite), much as the word steel encompasses all alloys, thereof.And, while carbon is amazing stuff to work
with, what has some of us bothered in the aerospace industry are sub-surface
delaminations which cannot be detected until a catastrophic failure of a structure
occurs.And, these are not false
Failed Airbus Vertical Fin Carbon Fiber Attachment Lugs
Think back to September 2001, and the American Airlines
Airbus A300 in New York
which shed its vertical stabilizer in-flight.Regardless of what “Officials” said about the First Officer’s “Stomping”
of a rudder pedal (rudder hard-over); the real cause was delamination of the
load bearing fin attachment points, which were all carbon composite.A host of other manufacturers use a
Titanium/Carbon combination to insure lightness, strength, longevity, and most
of all, serviceability.A Federal
Aviation Administration (FAA) certified repair station I used to work at kept a
1948 Cessna 140 as a parts-fetcher/lunch wagon/play toy.I could rudder hard-over on it all day and
the tail/rudder would not fail.Then
again, it is made completely out of aluminum.
Lugged Carbon Fiber Bicycle Frame
So, what does this have to do with bicycles?Well, the grade of composites used is pretty good
stuff, but it is designed for a ground based vehicle, thus supreme strength and
redundancy of load paths are not built in (in my opinion).They work well, do the job, and in many cases
look awesome, but stress loads are not their unique forte.
Now, the stress loads I refer to are primarily compression,
tension, and torsional, plus extreme bending loads.As a bicycle frame, the carbon will work
fine.Ride the bike out of its design
load and it will fail.This is where the
quality of the carbon comes into play, and unless the company you bought it
from tells you so, you have no idea where the raw materials came from, its
grade rating, who formed and cooked it, plus, who assembled the final product
(plus the risk of contamination).
I personally ride an aluminum frame, but that is due more to
cost consideration then a fear of carbon.Carbon composites are damn cool things, and you can do a whole lot of
things with them.My next bike probably
will be carbon fiber.I use the word
probably, being Titanium and Stainless Steel look almost too cool to pass up,
and I really like their durability.

Bottom line, carbon fiber bike frames, wheels and components
can achieve some pretty cool performance parameters these days.However, just keep an eye on your carbon bike
for any visible damage, and by all means, avoid extreme loading conditions like
Volkswagen sized pot holes, plus collisions with vehicles and immovable objects
(like your Mother-in-Law).It is a very
good material to work with, however, it is not THE material to solve all of the industrial applications for the
With this in mind, a decent carbon component, if properly
cared for, should last almost a life time.But, today’s carbon composites will definitely be outshined by
tomorrow’s carbon composites, and that is what I am truly waiting for.
Reynolds RZR Full-Carbon Bicycle Wheels - $4000.00 to $6000.00 USD.
The carbon fiber bicycle wheel.Whether Tubular or Clincher, they are light,
exotic, and sexy.They make us
faster.They give us status.They are flat-out cool.They are considered the “Holy Grail” of
bicycle components.They are also an
expensive double-edged sword.
So, just how dare I speweth forth such carbon blasphemy, you
say?It is simple really.Unless you are a sponsored racer, comparing
the cost/benefit analysis of the proverbial “Bang for the Buck,” is all it
takes to question marketing hype on the subject.
So, just what is the real price of achieving “Carbon
Bliss?”In actual, everyday life, this is
a perfectly viable question to ponder.In
this author’s humble opinion, one must be independently wealthy, a knucklehead,
crazy, or a combination of all to pop for a set of “Top of the Line” carbon wheels.
And, for the record, I too love all things carbon fiber just
as much as anyone, and I own a set of carbon clincher SRAM S40’s, complete with
aluminum brake tracks (I am not sold on full-carbon wheels).Not that full-carbon wheels are horrible, mind
you, I just question the amount of hype, the safety concerns, and I definitely
question the very real cost versus performance equation to the average cyclist.
Consider the following.
Back in the late 1970’s, early 1980’s, carbon wheels were a
pipe dream except in World Championship motorcycle racing where they were just
being introduced.It took a full 25
years, however, for them to be offered to the public at a cost approaching
reasonable and being built tough enough for everyday street use, if desired.
Today, for $4000.00 USD, you can own a set of full carbon
fiber motorcycle wheels which can sustain speeds in excess of 200 MPH.They can support a rider of any weight, are
strong enough to support load paths in, and from, all directions, including
having brake discs bolted to them, plus cushion drives, and sprockets.Remember, all this performance and durability
for about $4000.00 USD ($150.00 additional for ceramic bearings).Oh, and they come with a full warranty and
can conceivably last the life of the motorcycle.Heck, the price of a set of “Top of the line”
carbon bicycle wheels even makes forged Magnesium motorcycle racing wheels look
like a bargain at $3000.00.Or, one can
even procure a darn good set of forged aluminum wheels for about $2000.00
And remember, weight is just as important in the
motorcycling world as it is in bicycling.The technology that was previously the realm of Grand Prix racing has
now been brought down to the level of the everyday consumer.The results are predictable, too.They are showing up on street bikes, with the
durability to survive the pot holes and bad streets of the real-world we all
And, the benefits are real.A set of carbon motorcycle wheels can knock twenty (20) pounds, or more,
off a motorcycle.A set of carbon
bicycle wheels, meanwhile, will maybe take off a pound, possibly two in extreme
cases.In reality, it is only grams
we’re fighting with our wallets, which is why I call all of this madness in
cycling “The Gram Wars.”
Lightweight Full-Carbon Bicycle Wheels - $5000.00 to $6000.00 USD
As for the realities of carbon bicycle wheels, these puppies
can easily reach the same $4000.00 USD, and can even go as high as $6000.00 USD
(a price no motorcyclist would pay for wheels, this side of a MotoGP World
Championship team). This end cost of
product is a completely relevant discussion, as it is what we consumers are
being asked to swallow (or bend over for, depending on one’s perspective).In other words, what does motorcycling know in
total about carbon fiber wheels that bicycling does not?And, in even more basic terms, it is money
out of the consumer’s pocket that won’t go to rent, food, gasoline, or the light
The issues of reliability are very real, too.See, you can make something so light that it
basically becomes flimsy.That is called
compromise.Sure, carbon bicycle wheels
are asked to do a lot of things motorcycle wheels are not (and vice-versa), and
one of the major functions is braking.While MotoGP (and Commercial Aircraft, like the Boeing 787) can take
technology to the fullest, utilizing carbon rotors AND carbon pads, bicycling is still trying to get by with rubber
pads on carbon tracks, and doing a miserable job of it, too.Disc brakes will solve this issue,
So, what we have here are two different applications of a
similar material, however, in motorcycling, the wheels are being asked to do a
whole lot more for less money.And, that
is the basis of this article.
Additionally, the roads we ride upon are so bad (especially
here in sunny California, land of movie stars and the wealthy) that anything
less than a very durable, dare I say it, alloy wheel, is a waste of material
and money for anyone short of a sponsored racer.Yes, I state it boldly here – Carbon is nice,
but it is an oversold feature to the average cyclist.
But wait, there’s more.
I recently spoke to a friend of mine who is an engineer for
a major civil and military satellite manufacturer.Being they utilize a boat load of exotic
materials on spacecraft (yes, including a whole lot of carbon composites), I
asked him, off the cuff, how aerospace and racing can make carbon work reliably,
without all of the downsides that bicycling seems to be facing (heat issues,
stress load failures, and high cost).While admitting he was not familiar with the variables involved with the
bicycling world, he did state that in aerospace the issues of stress loading, reliability,
strength-to-weight ratio, temperature variance, and even to a certain point,
cost, had long since been realized with composites, including carbon fiber.What he ventured to guess in bicycling were the
issues of economics and weight, and figured the lack of a total wheel solution
in bicycling must be due to cost – It (reliability) could probably be done, but
at a price (and weight) that no bicyclist would pay for.
I then mentioned to him that you could get a set of
feather-weight wheels which possess hit-or-miss braking performance in the dry,
will not work worth a damn in the rain, and not take much abuse from road
irregularities for $6000.00.He just
laughed.“Why would anyone pay that kind
of money for something which was basically unreliable in most aspects of its
Well, they finally really did it. No, I am not referring to Charlton Heston's famous quote at the end of the original Planet of the Apes. Nothing that drastic, but news extremely exciting, none the less.
On Tax Day 2013, Chicago based SRAM took the opportunity to unveil new 11-speed Red and Force gruppo's, plus two new hydraulic brakesets - One for disc's, and the other for rim brakes. This is big news, people.
Political Correctness (PC) has turned people into a bunch of weak-kneed sissies. Case in point: Peter Sagan pinches a podium girl and people throw a fit. Sagan was forced (yes, he was) to apologize, and another victory over the human spirit was won by the PC Crowd.
Well, Australian cyclist Loren Rowney doesn't see things that way. In a brilliant bid to "Even the score," she turned the PC World on its collective head with a blantant, and welcome, butt grab of a race official.
And then... There was silence. No screaming, no tantrums, no Tweets gone viral, no, none of that. See folks, this is how the mature world handles things, and it is high-time we return to being adults, not sniveling, little children, ala, the PC World.

far?First, big wins in the Tour of

Trek Domane must be the real deal.From
Cancellara’s exclusive use of it over the magnificent Madone, to all those I
have asked their opinions about regarding its performance after a test ride.However, we can’t get took excited about it
can we, as Trek is the ride of that vicious, evil-do’er, Mr. Armstrong.Additionally, every test of the Domane has
returned very favorable results, however, there was always some nagging,
extremely subjective reasoning for not proclaiming it a winner in so-called
Take Velo News, for instance.Please!A blind man could have seen right through their “Objective Testing” of endurance
racers in the May 2013 issue.Not only
was the Domane dinged for issues totally unrelated to its performance, but the
Volagi Liscio was scored dead-last (with the Look 675???) while,
surprise-surprise, the Specialized Roubaix magically managed to best all-comers.Me thinks the crew over at Velo must be kissing
that big “S” tattoo on Mike Sinyard’s butt quite often.
The World Sport. Schwinn catalog, 1979
I rode a 1979 Schwinn World Sport yesterday.Wow, what a beauty to ride, she was.It had sat in a garage for the better part of
twenty-five years before recently being rebuilt by Pasadena Cyclery.I had not ridden a steel frame since the late
1980’s, and I was reminded why people like the material so much.While the brakes and Non-STI shifters were
not up to modern standards, the ride was nothing but smooth and produced a
whole lot of smiles.
2013 Raleigh RX 2.0 Cyclocross bike
I also tested a 2013 Raleigh RX 2.0, courtesy of Pasadena
Cyclery during the week.What attracted
me to this certain bike was the overall package it presents for a whole lot of fun
riding, regardless of terrain, mood, or whether one was wearing a kit or
not.Basically, I was looking for
something that I could just jump on and not care about jersey’s, bibs, shoes,
or cleats.A Cyclocross’er seemed to fit
The bike comes with an aluminum frame, carbon fork, Shimano
105 gruppo, FSA 46/36 crankset (gearing can be changed if needed), Avid BB5
mechanical disc brakes (with bar-top levers), and toe-clips.A smooth riding, fun, durable, twenty-pound, throw-around
bike, all for $1,100 on sale.This is
the kind of bike I would ride on the Pacific Electric Trail, as it would absorb
the bumps quite well with its size 32 tires.It could indeed be ridden in the dirt along the trail to escape the pain
of the concrete expansion joints.

Department, Zipp announced new 303 wheels specifically designed for disc
brakes.Also, SRAM leaked news of an
impending 11-speed gruppo, as well as hydraulic brakes.
So, will bicycling embrace road disc brakes?Paraphrasing Samuel Jackson from the movie Jurassic Park, “Hold onto your butts,” you bet
Shimano also let loose strong rumors of their own updated

I love it when the purity of cycling is laid bare for all to
admire – To those whom can grasp it, that is.See, in a time of all things exotic, carbon, colorful, and expensive, it
was nice to see the joy of two wheels is still appreciated by some.
How so?Peruse the
Unbeknownst to this pedaling scribe, until recently, there
is a group of very competent and fast riders that meet on Wednesday evenings to
circle Bonelli Park
here is Southern California.And it was there, among the sea of Lycra
and carbon fiber that they were seen: Two, new, young riders out to discover
what this whole cycling thing was about.And, doing it their way.
Astride bikes no one in the Peleton seemed to give a second
(let alone a first) glance at, they were on a Cannondale down-tube shifter, and

Classic Cannondale. Note the first generation Look pedals.
The classic Schwinn World Sport. Check out the rake on that fork.
While these two indeed had extremely lofty goals, that was actually

"The pinch heard around the World," it has been called. I'd call it the pinch felt around the world, as all the overly-sensitive people on the planet (namely Feminists and Metro-Sexuals) felt the need to cry foul over a harmless gesture even the Podium Girl did not mind.
A lapse in judgement? Poor taste? Sexual harassment? Nah, just a very young warrior being himself. However, in this Politically Correct (PC), pansy-assed, wussified, corporate world, unfortunately for Mr. Sagan, he may never be the same. Since all of this PC crap came out, the world sure never has been the same.
Me thinks cycling has real problems that need solving.
