Fausto Coppi's Code of Champions
2008-03-07 18:45:00
If you want a code to live by as a cycling champion,take these words that Fausto Coppi, the Italian campionissimo, wrote to the Carpano team in 1958. They quickly became known as the eight commandments of the champion of champions.1. Good manners are the first requisite of the rider.2. Show your education by the control of your tongue and by your bearing. A rider doesn't have to be a dandy, but he could be properly dressed.3. A rider must honor the engagements for which he has signed.4. Courtesy is the sign of a rider conscious of his responsibilities.5. Politeness is the foundation of all education.6. The journalist is the representative of public opinion. The rider is responsible in contact with the Press for his own standing, and he should help it to do its job without ever seeking flattery.7. Loyalty distinguishes a great rider, in competition and outside it.8. A rider must control his nerves in all circumstances and must accept good and bad luck with equal serenity.Picture Cou...

Active Spokes : Dynamically Weighted Wheels (DWW)
2008-03-07 00:32:00
Russel Kalil of Tarryan Technologies, who also happens to be an Ironman, dreamed up an idea that could make the best folks in the bicycle wheel business look dum.How about a wheel that could increase and decrease its moment of inertia according to your riding speed? As a cyclist rides up hill, weight transfers closer to the hub and while he descends with the added speed, the weights move out to the rim for the extra momentum.The concept is simple. You don't need a new wheel nor have to rewire your brain like pedaling on Power Cranks. Active Spokes uses small sets of weights (each weighing 0.5 oz) in 3 sections that fit onto the spokes of the non-drive side of your existing rear wheel. The choice of these sections depend on the average speed of the rider.With speed, the centrifugal force in the wheel moves the spring loaded weights far out towards the rim. The motion of the pieces can be manipulated with a choice of springs that have different constants. More on this technology and ...

Mavic R-Sys Failure
2008-03-05 20:27:00
Mavic has made some good wheels in the past. On the whole, they may not disappoint with the new R-Sys Wheelset.However, I also don't see much point in its carbon fiber spokes. Something more controversial is their cross section. A bicycle wheel typically has 24-30 spokes and while in movement they churn the air. The R Sys's bigger and rounder spokes depart from the norm in thinking about aerodynamics. What you end up getting is an expensive but stiffer wheel which eats a bigger percentage of aero drag than its cousins.Chris pointed me to a Mavic wheel "explosion" after a crash during Stage 1 of the Tour Down Under. This bike was ridden by Karl Menzies. Notice that the wheel has detached from the hub and the spokes jut out in a unique fashion. I wonder whether low spoke tensioning had anything to do with this. The wheel doesn't appear bent but its hard to see from this angle.Courtesy : Graham WatsonThe photo was probably taken while the crash was happening (with a broken wheel be...

How a Clipless Pedal Works
2008-03-03 22:13:00
Hey! Want to say screw off to your enemy at the races?Yes, just do it. Screw off.No no no hold it! Hold it ... I didn't mean THAT!!I meant : Take a screw off his pedal cleat when he isn't looking. Literally.Well, I'll come back to this in a sec. First lets see how a clipless bicycle pedal works. All the nerdy wordy descriptions aside, I'll let you look more at pictures.This is the Shimano PD-520 Pedal , a set of 3 year old beaters I have on my fixed gear. This version is made in Malaysia.1 and 2 are the clipping sites for the cleat, something you attach to the back of your shoe. 3 is the body, 4 the spindle, and 5 is the threading that fastens into a crank arm clearance.Member 2 is able to move back and forth (black arrows below), whose resistance to do so is set by tensioning a torsional spring 6.As one rotates an adjustment screw clockwise (purple arrow), the black spring 6 moves outward shown by the red arrows, clamping member 2 at its outer arms more tightly.

The Story of Bike Nashbar
2008-02-29 03:13:00
Note : Some portions of this post are on the speculative side due to scarcity of information. A bigger discussion of this post can be viewed here, for which I thank the RBT readers.If there's a more well known and unique-in-name local bicycle shop killer than your wife who says you can't buy any more cycling stuff this month with the savings, its got to be Nashbar.Some also call it Trashbar.In 1974, Arni Nashbar, a New Middletown Ohio advertising man, started a bicycle parts mail order company out of his home with $1,000. He did this possibly believing that a small company can make more money on items sold through a catalog than through retail. Since this was way back, we don't exactly know how it happened. Some people believe he bought out the business from an initial holding called Bike Warehouse, giving it his name - Nashbar LLP.Whatever the story, ten years later, the company was grossing six million plus.Arni's mail order business was thriving so much that in the late 80's...

Is This a Season Kick-Off?
2008-02-28 00:27:00
This is the question I have been asking myself.The racing season seems to be opening in Buffalo this weekend, with the Giro della Primavera (Race of Spring) Training race series that will stretch out to the end of March. Each weekend has about 60 miles of racing and possibly close to 70 miles of riding. Saturday races are pretty flat and chances are they'll be fast. Sundays have a bit of rollers, but I prefer going to Church.So its a question of racing on Saturdays in 30 some degree temperatures! I sure don't have those solid pro instincts in me, but the look of this race series sounds like it'll at least begin that development process. Besides, Stage 5 of the Tour of California should also be a motivating factor.Last years Giro's are still colorful to me, when I was a fledgling new born in bicycle racing. I met some interesting characters, including a quite youthful 70 something old Italian veteran rider named Ron Palazzo who decided that I need some coaching, Italiano style. T...

Women Cyclists : Not in Vogue?
2008-02-25 21:50:00
I have found reading about Jeannie Longo so fascinating that I had to devote a post on her.I first heard about her in the work, Tour de France - Three Weeks to Glory by Samuel Abt, now a poor, old and torn book lying on my bookshelf.Its a little unreasonable that women are excluded out of our daily coffee table cycling talk. We easily remember Lance and his super human feats, how Merckx took part in almost every event in the racing calender and possibly managed to win them all, about Anquetil's relentless French conquest of the early Tours, Levi's time trial prowess, boy Boonen's classic but surely rabid sprint wins, Cipo's flamboyance this, Bartali and Coppi's that ... and so on and so forth.And so when it comes to publicity campaigns,flashy magazine ads or even a subjective agreement on who the greatest cyclists are, its quite obvious to see that limitations are only to men.How about the other gender, possibly half of the 6 billion people on earth? Even if a .01% of them bike...

Tour of Cipollini (TOC)
2008-02-20 01:30:00
There's the Amgen Tour of California '08.And then, there's Mario Cipollini.Who cares about the Yellow Jersey, when Lion King just awoke from a retirement slumber.With some 1 Million Euros to pay back to the Italian government in taxes, a face like this in court will surely scare the prosecutorsCourtesy Graham WatsonThe much publicized return of Mario to pro cycling has not failed to deliver. His larger than life celebrity presence just overwhelms the start line.Whats even more amazing is his ability to stay at the front after all these years of absence from the pro scene. If there's anything more defining about him, it is his veteran status in the dirty, cunning world of speed. He knows this game all too well, perhaps more than anyone else.Ok, granted the climbs haven't come yet but still... What do you guys think?

Dubious Frame Cracks
2008-02-19 00:04:00
Here's a crack on the down tube of a carbon fiber composite Cannondale System Six, noted by the user after 3 months of regular riding. The clear coat is surprisingly intact. Cannondale agrees with the user's dealer, concluding that it resulted from a crash. A crack without damage to the clear coat is dubious. It seems to me to be a fault during manufacturing or packaging.One can see the crack in good lighting.Here's another 'crack' in the top tube of a Scott Addict Limited 2007. Again, the clear coat is in near to perfect condition. It almost looks like a cosmetic flaw to me, but with carbon fiber, you can't take any chances.Both sound like warranty issues and should be communicated with the dealer, or the bicycle company itself.

The Kano Diagram Applied to Cycling Products and Services

Dr. Steve Shooter is a professional and practicing engineer at Bucknell University. He focuses on topics in product design and development and some of his videos on You tube are just fantastic material.Here, he explains the Kano Diagram, a model used to measure how well a product or service meets customer requirements. This concept is a basic topic in engineering design courses, but you don't necessarily have to be one to understand it.

The President's "First Mechanic"

President Bush clearly has this unique celebrity status in contemporary history. Its always fascinating to know whats going on at his end. Well, we always do, don't we, but those little silly things that don't make it to mainstream media often paint a different picture about him. [insert favorite description here..]I pointed you out to an an article in the past about the President's love for mountain biking. A few of you readers were shocked after realizing TREK and Cannondale supplied the President with the "First Bicycles".

Bamboo for Bicycles PART 3

Bamboo Fixed Gear, anyone?Here's the third installment of this series. I am so fascinated by this material that I didn't have a word limit for the other two posts. I'm sorry to those who're saturated with bamboo but I didnt want to leave any strings loose in the air, so to speak.If you read Part 2, you may have noticed the unanswered questions on Nick Frey's Bamboo bike that I said might sooner or later be revealed.In this post, Nick replies to them so we can get an idea of what his ideas are and where he's going to go with them. For me, it was a good learning process and I was quite appreciative of the fact that he spent some time out of his training and school to detail the building process with me.A quick recap : Nick Frey is a mechanical engineering junior at Princeton University. He's also Espoir National Time Trial champion. He and friends teamed up to build a practical wooden road racing bike for a design project at school. They went from one to two and now three bicyc...

Bamboo for Bicycles PART 2
2008-02-08 04:58:00
With the help of some research accumulated in Part 1, we were able to describe some astonishing features of bamboo, a natural composite material. You can learn several other interesting attributes of bamboo through the American Bamboo Society and Bamboo Web.Bamboo also comes with a fair share of disadvantages.Disadvantages1.Bamboo contains about 2-6% starch, 2% deoxidized saccharide, 2-4% fat, and 0.8-6% protein.The carbohydrate content of bamboo plays an important role in its durability and service life. Durability of bamboo against mold, fungal and borers attack is strongly associatedwith its chemical composition. Bamboo is known to be susceptible to fungal and insect attack.2. Bamboo needs to be preserved like timber; the natural durability is less than that of timber.3. The fire risk is higher for bamboo than for timber.4. Since bamboo culms (stalk) are a product of natural growth, no two culms are alike. This makes it more difficult to realize joints. Also more effort...

Bamboo : Nature's Composite PART 1
2008-02-08 03:22:00
If there's anything more widely available, naturally made, tough as steel and sturdier than concrete, with probably more observed vibration dampening than carbon fiber, its got to be bamboo.What is it? Bamboo (Dentrocalamus strictus) is a natural composite material, in which cellulosic fibres are embedded in a lignin matrix. Cells of bamboo have been categorized into two types: matrix tissue cells and sclerenchyma cells. StructureMatrix tissue cells are leptodermous and act as the matrix. Sclerenchyma cells consist of vascular bundles are enveloped in the matrix tissue. Vascular bundles act as reinforcements in bamboo. A vascular bundle is made-up of several phloem fibres. A phloem fibre is made of several layers of pillar fibres. Micro-fibres in each layer of the pillar fibres are spirally arranged at a fixed spiral angle, which varies for different layers of pillar fibres.A vascular bundle is made-up of many right-handed spiral phloem fibres. Chemical constituents present in bamb...

Manufacturing : Detailing and Assembly

Looking at the pictures above, what on earth do you think the guys at Guru Bicycles are doing? Are they systematically torturing their bicycles into submission? Will they work better this way?Any guesses?None of those wacky ideas.The Canadian manufacturer calls it the Detailing & Assembly Stage. They have one for both bottom bracket and headtube areas. Its basically a cleaning operation before they assemble components onto a finished and painted frame, be it aluminum, carbon fiber composite or titanium. This is a standard procedure.In Guru's own words, from their excellent website :The threads within the bottom bracket, along with its outside walls, are systematically cleaned with special tools to eliminate any lingering residue. Another small step that makes a big difference. This one ensures the proper functioning of all gearing components, while minimizing any power-draining friction.We do the same detailing job to the head tube in order to assure an optimal functioning of t...

Cracks in Saddle Shell
2008-02-05 01:22:00
First and foremost, famous bicycle guru Sheldon Brown is no more. Most of us serious cyclists must have touched upon his website at some point. The amount of knowledge and documentation he has provided on possibly every aspect of the bicycle is unmatched. The last conversation I had with him was sometime last July, where we talked about Colnago bicycles. He'll be really missed by the cycling community.Shown below are some cracks on the underside of Chris' saddle. He has replaced it which is good for him.Shell s are, I would think, made of some kind of thermoplastic polymer. I'm also guessing crack propagation was from the sides towards the center, by looking at the picture For example, the first one on the left starts out from the groove just below the saddle covering. The second one seems to shoot out from the right pin all the way to the left. Also notice discoloration around attachment pins.

Perspectives #1 - Transport Efficiency
2008-02-05 00:22:00
Energy consumption is costly and steadily increasing today. A majority of production and consumer buying decisions are based around efficiency of the product they are designing or purchasing. With this in mind, it will be nice to have the moving transportation system in question have as little dead weight as possible and more payload weight instead.Dead weight, denoted by Wempty, like dead load in structures, is non-productive and costs money to move around during its economic life.Payload is the part of the transportation system, other than structural items, that will gain something (like humans moving from one position to another) or it will generate money for some other public party. Weight of the payload is denoted by Wpayload.When considering the Wempty/Wpayload ratio, interesting results are observed. This ratio is a dimensionless paramter by which we can have some amount of idea of transport efficiency. Generally, we want this ratio to be as small as made possible with the ...

Its a one size fits all design, comes in different colors, and those who have used it clearly seem to love it. The company claims their design is the result of countless studies and trials.It is an interesting idea that has been conceptualized and maybe tried before : Poke a lot of holes in your super stiff saddle shell, keeping a good distance between each hole so it flexes wherever you want it to.In the Rido, notice the wide sitting area and the bigger holes in the middle portion, where the sit bones seat (ischial tuberosities) .From their website :The RIDO saddle's construction is a unique monocoque sculpture TM, a patented technological manufacturing revolution in itself, specially developed to fulfil the design's requisite combination of localised flexibility and rigidity and doing ...

Broken Steerer Tube : Composites Are Not Perfect

Thanks to some high quality pictures from Erik (I hope I got the name right), we can now visualize a suspect carbon steerer failure in high resolution. The bicycle is a Bianchi Virata, possibly from the company's 2006 lineup. Some pictures of Erik's injuries can be viewed here (since he's made the page public). Lets hope he has fully recovered.I notice how the metal-cf bond has failed at the headset junction, and the fiber within has just snapped like straw. Honestly, I do not have a lot of composite experience so I cannot really tell you how this fork failed. Only Erik knows best what he did with the bike before this happened. We can sit here and postulate too. But I'll be posing this question to some composites experts. Understanding this culprit is vital for my brain's health.Composites consist of a combination of materials - a matrix and sheets of short or long fibers. Each of these two have their own characteristic properties and when combined together and designed well, ...

Lost in Words : Pinarello ONDA Fork Design
2008-01-30 02:18:00
Pinarello has been making some great looking bikes over the past 20-30 years or so. In an industry which has only so much freedom to play around in (primarily due to the UCI restrictions), the Italian company has been taking some bold steps with its radical designs such as magnesium alloy framework, proprietery headsets and S-bends in more places than you can think of. While many adore the eye catching paintwork and curvylicious exterior, a fair share of others also think its simply overkill.This factory is responsible for those curves in your Pinarello. Some sections of Pinarellos also seem to be made in China but I'm not sure about this.Pinarello has a patented method of attaching the front triangle to the monostay (or rear fork). As I saw the fatigue testing of one of their wavy forks, also called "ONDA" , I asked myself : What possible advantage could this radical shape really offer?Keen observers will have noted that this is not the first time a wavy design has been incorporat...

Full sized human riders are a disadvantage in wind tunnel tests. They are fat in the offseason, lazy, bored, cold, suffer tunnel vision, grumble/scratch when asked to sit still in the aero position, complain of stiff joints, sore muscles, and often ask unnecessary questions over the prospects of surviving while meeting the turbo fan eye to eye.With all the downtime from the above considered, the costs ofblowing precious air at these undeserving folks (wax models included) are overwhelming.Irritant testers have ordered an assessment study for a new rider design, fully manipulating the fluid dynamics principle of Geometric Similarity.

The Bio Composite Race Bicycle - Part 2-

The top tube slopes slightly from head to seat, not too much, but enough to help handling and stiffness. The head tube is bulky which keeps the frame stiff and cuts down on torsion stress, the seat stays are of a wishbone design and the seat tube has an aero profile. The MF-1 is strong and light, everything you need from a bike frame, it's not cheap, but a frame of this quality is never going to be a give away.Luxurious Lugged DesignAnother review from Cycling weekly is here, and it talks about the bike, components, wheels and ride quality.So what it is tubes combination of carbon with fiber, produced by a patended high temperature and pressure process, and these tubes...
