AAA Encourages Motorists to Share the Road

Cyclists found an unexpected ally this week when the American Automobile Association (AAA) urged motorists to share the road with cyclists.

Jake Nelson, director, AAA Traffic Safety Policy and Research stated:

“It is important for roadway users to remember that cyclists are granted the same rights and are expected to obey the same laws as motorists.”

The AAA article went on to advise motorists:

• Allow three feet of passing space between your car and the cyclist. Tailgating or honking can startle or fluster a bicyclist, causing them to swerve further into the driving lane.

• Be patient. Remember, cyclists are moving under their own power and can’t be expected to go the same speed as cars.

• Pay special attention to blind spots. Due to their size and the location of bike lanes, bikes can often get lost in a car’s blind spot, so double check before changing lanes, making right-hand turns or before opening your car door on the traffic side when parked.

• Be attentive on side streets and neighborhoods. Children are especially at risk in residential areas. Follow the speed limit, avoid driver distraction and always be aware of your surroundings. It is particularly important to be cautious when backing out of a driveway and onto the street.

• Use good common sense. For example, in inclement weather, give cyclists extra room.

I find it encouraging when probably the largest motoring organization in the world, with 51 million members, issues a statement like this.

I have noticed a change in attitude in the media in general, over this last year, to one of more tolerance towards people who choose to ride bicycles.

I am confident this trend will continue, and it time more people will be encouraged to join the cycling ranks.

Kudos to the AAA

Generations

Every ten years or so a new generation comes along.

As one generation reaches childhood, the next is being born, and the previous one are teens or young adults.

Each generation thinks they know more, or they can do better than the generations before.

Every previous generation looks at those who follow and invariably says, “God help us in the future.”

I was born in England in the mid 1930s; in the middle of the Great Depression. By the time I reached my childhood and was old enough to be conscious of my surroundings, I found myself in the middle of a World War.

I had a father, my mother told me so, but I didn’t remember him; he had left in 1939, within days of the war starting. Apparently his last words as he left were, “It’s just a scare, I’ll be home in a couple of weeks.”

He was gone almost five years, came home briefly in 1944, and then was gone again until the war ended.

I didn’t really understand what to be in a war meant. I knew my father was fighting in the war, fighting the Germans; (Whoever they were.) but knew no reason for it, or for that matter even considered a reason.

I only knew what my mother told me, and what the other kids at school told me. Not that they really knew any more than I did, just what their mothers told them.

I remember the American soldiers coming over prior to the Normandy Invasion in 1944. They seemed like adults to me, but looking back they were just teens; only one generation before me. Happy, laughing, goofing around as teens will do.

This generation, often referred to as the “Greatest Generation,” born just ten years before me; little more than kids themselves, were actually fighting in the war.

Handing out candy to kids like my friends and me in the early part of 1944, then dying on the beaches of Normandy in their thousands, a short time later.

The generation after me was just now being born in the mid 1940s; they would reach their teen years in the 1960s and become the generation that protested war.

Did that generation know more about war than I did? When I was a teen, WWII was only a few short years past, but with its implications never fully understood, it was quickly forgotten.

I was part of the “In Between” generation, I reached my teen years in the 1950s. I didn’t have to fight in a war, and I missed out on all the excesses of the 1960s. I’m not sure if there were teen cultures before us, but there certainly have been every generation since.

We were the first after WWII; we were known as "Teddy Boys." Wearing clothes fashioned after the styles of the "Edwardian" era. (The early 1900s.) In the picture at the top I was eighteen years old; the shorter of the two, on the right.

Teens generally dress and all follow the same trends as their peers, and strangely they do it in order to be different; in actuality the generations that follow the previous are not drastically different.

We all fuck up along the way; some of us have a few more successes than failures, but does anything really change?

Does our lot get any better? History repeats itself, and each time the price goes up. We are still fighting wars; we in the middle of a recession, which is another name for a depression, which is where I came in

Fog lines and rumble strips

Savannah Highway (Hwy 17.) is the main road south out of Charleston, South Carolina.

It is a divided highway, (A dual carriageway in the UK.) with two wide traffic lanes on either side. It has a continuous fog line painted on the left, with a shoulder almost three feet wide.

“Share the Road” signs are posted and one would think with so much space, this would be a safe place to ride a bike, but you would be wrong. Traffic flows by at around 65 mph; freeway speeds.

Have you ever noticed how a large number of drivers habitually hug the right-hand edge of the road? It doesn’t seem to matter how wide the road is, if there is a shoulder they will drive with their inside wheels over the fog line.

If they are tailgating the vehicle in front of them, they will not see a cyclist until the moment of impact.

This almost happened to me the last time I rode this stretch of road. Traffic was very heavy and I was buzzing along on the shoulder, enjoying the tow that the back draft of passing traffic was giving me.

Suddenly there was a squealing of tires behind me and a Cadillac Sedan came by missing me by inches. Out of control, and fishtailing all over the road, and ended up sliding sideways across into the far lane.

With so much traffic it is a wonder there was not a major pile up, and had this been an SUV it would have rolled over for sure. However, the driver regained control and continued on without stopping.

It was obvious to me what had happened. This driver was over the fog line, and had seen me at the last second, over corrected and temporarily lost control.

I never rode this stretch of Hwy, 17 again, and in case you are wondering why I rode it at all, it was to get to Main Road leading onto John’s Island where there are some very nice quiet country roads.

After this incident I rode the West Ashley Greenway, which is a dirt bike trail. Alternatively, if rain had made the trail too muddy to ride, I would ride Bee’s Ferry Road, a two lane highway with a shoulder. Traffic speeds are slower, so slightly less dangerous than Savannah Highway. 

One of the nicer roads to ride on John’s Island is Chisholm Road. It leaves Main Road, just after crossing the Stono River; it makes a ten mile loop the joins up with Main Road again. It is a road that goes nowhere and so gets very little traffic.

The only people who drive this road are the residents of homes on Chisholm, and they are used to seeing cyclists along that stretch. Much of this road had a decent shoulder, at least 18 inches wide in places.

When I recently rode there, I noticed they had re-striped the fog line, and used some special process that made a little raised bump every 12 inches or so. In other words, the white fog line had been turned into a rumble strip.

Initially I thought, “What a great idea,” keep those people who hug the edge of the road, off the shoulder.

Then I noticed all the debris from the road had been swept by passing traffic onto the shoulder.

Dirt, dead leaves, etc; and in places the grass was beginning to grow over onto the shoulder. The affect was Chisholm Road had become narrower.

No doubt rumble strips keep the local “Good ‘ol Boys” on the straight and narrow, and rubber side down while driving home late at night.

However, they do little to help the cyclist on a Sunday morning ride. Roads like Savannah Highway could really use rumble strips, to keep the motorized traffic off the shoulder making it safer for bicycles. As yet it doesn’t have them.

However, the shoulder would then need to be swept on a regular basis to keep it clear. On country roads like Chisholm where it would be cost prohibitive to sweep, no rumble strip would be better and let the passing traffic keep the shoulder swept clean.

Just a thought

The Cambio Corsa: Campagnolo's Early Masterpiece

Necessity is the mother of invention, is the way the saying goes.

When Tulio Campagnolo stood on a cold mountain top, and couldn’t unscrew the wing nuts on the rear wheel of his bike because his fingers were frozen, he soon after invented the quick release hub.

This was back in 1930 and lead to the forming of the company that still bears his name today.

In 1940 Campagnolo invented the Cambio Corsa derailleur, which utilized the same quick release mechanism.

 

The now famous picture above shows Gino Bartali shifting gear with the Cambio Corsa on a steep mountain pass during his winning ride in the 1948 Tour de France.

For its time, the Cambio Corsa was a masterpiece of engineering, yet so simple in the way it worked.

There were no jockey pulleys to take up the slack in the chain as it moved between large and small sprockets.

 

Instead chain tension was achieved by the rear wheel actually moving back and forth in the rear dropouts.

Below are Tulio Campagnolo’s original drawings.

 

The standard sprocket width of that era was 1/8 inch, and there was no narrower chain available. This meant, at that time the maximum number of sprockets mechanically possible on a freewheel, was four.

 

Gear teeth were machined into the rear wheel axel, (Picture above.) these engaged in a rack consisting of teeth machined into the upper part of the frame’s extra long rear drop outs. (Picture below.) 

This allowed the rear axel (When released.) to roll back and forth along the dropout rack, keeping the axel square with the frame. The wheel, although moving back and forth, stayed central within the chainstays.

The derailleur was operated by two levers on the right side of the bike’s rear seatstays, just below the rear brake. The top lever released the rear wheel, a lever below it operated a simple guide that moved the chain from one sprocket to the next.

Because this chain shifter was on the top portion of the chain, above the chainstay, it was necessary to back pedal to actually shift. The pull of the chain as it climbed over the teeth of the sprockets, moved the wheel forward. Once the shift was made, the rider’s weight automatically moved the wheel back and re-tensioned the chain.

Sound complicated? Actually it wasn’t as these videos below show the Cambio Corsa shifting down,

 and shifting up.

The gear shift in the hands of an experienced rider is so quick, you will have to view these videos more than once to actually notice the rear wheel moving back and forth.

The videos are from Aldo Ross and can be viewed here.

Here is a link to the page showing how the camera was rigged to get these videos. People like Aldo Ross do a great service to cycling. Many will never see a Cambio Corsa derailleur, and even fewer would get to see one actually working were it not for these videos.

There are more pictures here, and more history here

Fashion Faux Pas

In 1981 when working for Masi in Southern California, I went to a bicycle trade show in Atlantic City, New Jersey.

Falerio Masi, founder of the company, flew over from Italy and met us there on the opening day. When I arrived at the Masi show display from my hotel that morning, Falerio was already there and very upset.

He was speaking in Italian through an interpreter and flicking angrily with his finger tips at the brake cables on one of the bikes on display. I did not need to know what he was saying; I knew exactly what the problem was and why he was angry.

The bike was set up (Similar to the bike pictured above.) with the brake cables running under and in front of the handlebars. This was a huge fashion Faux Pas in Europe, it drove me crazy too.

Brake cables were supposed to flow in a pleasing curve from the brake lever, to the front brake, and to the top tube en route to the rear brake. The brazed on cable guides were precisely placed along the center of the top tube to facilitate this.

I heard Falerio Masi told,

 “It is no big deal, and Americans don’t care about such things.”

That statement was probably true at the time. Many bikes being sold and ridden in the US were bought by people who today would buy a Mountain Bike, or a Hybrid. They were often set up like this Fuso (Above.) that came up for sale on Craig’s List last week.

Frames were usually too big for the rider. (By European standards.) The result was, the saddle was too low, and usually the bars were set too high. The brake levers are set too high on the curve of the handlebars, and the levers start to stick out front like a pair of six-guns.

This all indicates to me that the rider never should have been on a dropped handlebar bike in the first place, and I would rather have seen this bike set up with flat handlebars than set up looking like this.

On an “Old Skool” bike, the external brake cables were an important part of the aesthetics of the overall look. On my own bike for example (Above, and close up below.) notice how the cables leave the brake hoods, following the same curve of the lever.

Notice how the rear brake cable flows from the brake lever to the first cable guide on the top tube. It doesn’t matter if the front brake is on the right or the left, that is a personal preference.

The top of the curve of the cables just happen to be level with the top of the saddle, which has nothing to do with anything. However, this being my correct size frame, the handlebar to saddle height ratio is also correct, this is most likely the reason why it turned out that way.

Because when form and beauty meet function, there is harmony and balance. A  machine set up to perform correctly from a functional stand point, will also look right from an aesthetic view point
