They dissagree with your theory in almost all respects.


We are very familiar with "them," although you don't seem to realize
that "they" are Randy Swart, a single person who since about 1975 or so
has devoted his life to the dangerization of bicycling and the promotion
of mandatory bike helmets. That's for everyone, including adults.

Swart copies and publishes every bit of pro-helmet nonsense he can find.
For decades, he was one of the loudest trumpeters of the purported
"85% benefit" from the 1979 Thompson & Rivara "case-control" study.


Sorry, typo. That was 1989. But its "85%" is still uncorroborated 28
years later.

Any safety equipment that is not overly intrusive is worth using

??? Really??

OK, do you wear a bike helmet when driving to the start of a bike ride?

I wear my bike helmet whenever I ride my bike(s)
If you mean when in my car, don't be stupid. I guess I have to
stipulate any "appropriate" safety equipment.


You're deciding what's "appropriate" based on fashion driven by
propaganda. You've been told it's appropriate to wear a helmet when
riding a bike - but why?

Is it because bicycling is a major source of traumatic brain injury?
No, it's only about 1% of the TBI problem in America. Motoring and
walking cause far more.

Is it because the risk of serious or fatal TBI per mile traveled is so
high on a bike? No, it's roughly 1/3 that of walking, per mile.

Is it because the cost to society of bike TBI is so high? No, it's
dwarfed by the cost to society from auto TBI, not to mention just
walking-around-the-house TBI.

Is it because your collapsible steering wheel, air bags and seat belts
remove the risk of motoring TBI? No, despite those features, riding in
a car causes huge amounts of TBI.

I'm not making this stuff up. Car helmets have been very seriously
proposed, and those proposing them have pointed out that they'd be much
more cost effective than many other measures, like air bags. They could
be far more pleasant to wear than bike helmets, too, partly because of
the non-exertion and climate control.

Don't distract us about welding without goggles or grinding without
safety glasses. Your ability to name two appropriate bits of safety
equipment doesn't make all safety promotions rational.

If you want to argue for bike helmets, first look at relative risk
levels for individuals and at relative costs to society; because it
makes little sense to put huge focus on a nearly non-existent problem.

Then look at actual effectiveness, or lack of same, in the real world,
not in tiny and confounded "case control" studies. (For example, you
might try to explain why pedestrian fatalities have fallen faster than
bike fatalities for the past 20 years, given that pedestrians stubbornly
refuse to wear helmets.)

Then you might deal with the benefits vs. detriments of bike helmets and
of the "dangerizing" of bicycling. Every study done on the topic has
found the benefits of bicycling FAR outweigh its tiny risks. Why would
you scare people away from riding by pretending it's safe only with a
weird plastic hat?

Like I said, we will have to agree to dissagree. Read the data I sent
you.

Not saying cycling is inherently dangerous, but it does have it's
risks - which can be significantly reduced by wearing a suitable
helmet.

Cheers

Out of curiosity I weighed and measured the chain tool that I carry in
my bike tool kit. It is 2-1/2 inches in length and 2-1/8 inches in
height. 1/2 inch thick, at its thickest, and weighs 2.6 ounces. It
works with chains up to and including 10 speed chains (I don't own an
11 speed). Frankly, as a broken chain immobilizes the bicycle I can
see no logic in not carrying it.

Since I have never once had a broken chain nor seen one I cannot see any
requirement to carry such a tool. Yesterday I did 55 miles and 2500
feet of climbing with some of it pretty steep ~12%. There were fore of
us there and the dirt encrusted on the bikes showed a certain lack of
careful maintenance. No one had any problems. I have been carrying all
these tools around for the last 6 years and the only one's I've used
are the tire repair tools.

Equally, I have had two crashes severe enough to break bones and in
neither did my head strike the ground. Thus, based on your logic,
there is no reason what so ever to wear a helmet.

There is almost no reason to wear a helmet under any conditions. If a helmet was just barely able to protect me in a fall literally from 18" what makes you think that a helmet can do anything other than protect you from getting scratches on your head in a sideways fall at a dead stop?
My oldest daughter hit her head on a concrete retaining wall hard
enough to crack the hardshell bike helmet and came away without a
scratch (on her head - she did get a bit of "road rash" elsewhere)-
and most certainly would have suffered a concussion without it. The
foam lining and hard plastic shell absorbed a LOT of impact.

I would suggest that you don't understand the nature and causes of concussion. And that you don't understand the mechanics of impact. Where did you get a hardshell bicycle helmet?

I don't know the age or weight of your child or what "retaining wall" means. Colliding and hitting your head in the forward lunge is NOT the same as falling off of your bike and taking the brunt of the collision with the ground on your head.

Sorry, but you would be wrong. I understand that concussions are
caused by the head decellerating too quickly, causing the brain to
bruise or twist inside the skull. I also know that compressing an inch
of foam can increase the time taken to slow the head to a stop - in
actual testing, about an extra 6ms - which changes the effective
impact significantly - reducing the peak impact force by more than
half. It spreads the force over a longer time - reducing the
decelleration.

When I say Hard shell, I don't mean fiberglass - this was a fairly
tough polypropelene shell - they were pretty common here in Ontario
Canada 20 years ago.
She was riding down a hill when the pedal broke and she lost control,
veering into a retaining wall made of bags of cement which was used to
stabilize a steep bank beside the road (the road is in a "cut") She
came off the bike sideways, hitting her head on the wall, and also
hitting her shoulder. Helmets protect against impacts whether caused
by the acceleration of gravity in a fall, are due to forward velocity
(which CAN be much higher than a strictly gravitational fall from
about 4 feet)


Lots of information that does not support the interpretation of
increased injuries due to helmet use here.

http://www.helmets.org/stats.htm

Also you need to talk to paramedics and emergency room physicians.
You will get a different story than Frank's.


I've talked to a woman in our bike club whose full time job was TBI
rehabilitation. This was back in the 1990s. She admitted that in seven
years of full time work, she'd encountered only one bike-related TBI
victim, and he was a racer who had been wearing a helmet when he crashed.

Look up the numbers of TBI victims sorted by activity. Fatality data I
found indicates that bicyclists are only 0.6% of TBI fatalities in the
U.S. And again, that's not low because of the helmets. See
http://vehicularcyclist.com/fatals.html and
http://vehicularcyclist.com/kunich.html

Read this: http://ohiobike.org/images/pdfs/CyclingIsSafeTLK.pdf

If you hit TBI websites, you'll see that bicycling is usually not even
mentioned in ranked lists of causes. Yet the myth of great risk
persists. And the myth of great protection is nearly as strong.

Like I said, we will agree to dissagree. I have provided links to
opposing data - others can make up their own minds.
You are in a small minority, even of Cyclists, who oppose helmet
wearing.

Whether I carry a chaintool is the result of the probability a chain
breaks multiplied with the severity of the consequences when it happens.
The outcome for me is off road I carry one, on my roadbikes I don't. This
applies for all tools.

Lou


My multi-tool thing has a chain tool so I carry one all the time.


I don't carry a multitool on my roadbikes either.

I don't
think I've used one in over 20 years though.


There you go ....


I mean I haven't used the chain tool. I have had to use the allen
wrenches and other tools occasionally.

Last time I used one it was
handy to have though.


What would have happened when you didn't carry one at that moment?



The chain tool? I would have had to walk maybe 30 miles to a telephone.
This was before I had a cell phone.

Even now, if I do a 120km ride, I'm usually leaving Montreal and heading
to the country. Trying to get a cab or something 60 km from anywhere is
seems more difficult than carrying a tool to fix the broken chain.

I'm just saying that's what I do. I'm not insisting anyone else does
anything.

Except that if I lived in a mountain lion infested area where the riding
was so much more difficult than Quebec and you had chains breaking on a
daily basis, rather than looking for a rock and a nail in the woods, I'd
carry a chain tool.

168 gram Geezzzz.. ;-)

Yeah, my god, another 1/4 pound on my 15 lb bike. That's almost 1 less
cheeseburger!

Technically, the chain tool is probably 20 grams as I would carry some
sort of tool anyway. g


I don't think that the question is "can" you carry a chain tool as much as SHOULD you carry a chain tool. I ride several bikes and they all have the flat kit and a spare tube and they all have a multitool. One of these multitools has a chain breaker on it. I don't expect to ever need it because I never have in the past 40 years. Or you could carry nothing more than a masterlink and a normal screwdriver and if you broke a link you could pry the other side off and insert the masterlink.

Firstly you didn't give any previous stats that I saw.

Secondly there ARE no competing stats. The strength of a bicycle helmet is FIXED by the depth of the helmet and that is fixed by the size of a helmet that people are willing to wear. The present bicycle helmets available are as large as people will wear and they show that by not buying larger helmets.

And because the depth of the collapsible core is fixed by the available depth of the helmet which is fixed by what people will buy, it is TOO RIDGED to give significant protection in a normal fall let alone any serious crash.

This means that even a minimum fall as I had while bending over to realign my speedo pickup and with my head less than 24" and more likely 18" above the ground and travelling 5 mph or so exceeded the capacity of the helmet to protect me from a concussion.

Because you want to believe in a magic dragon that can protect you from anything doesn't mean that imagination has any place in the real world.

I, like Frank, am an engineer and we very well understand these problems.

In my car (which has a colapsible steering column, air bags, and seat

an approved helmet and good shoes/boots. I would NEVER ride in shorts
and tee-shirt wearing flip-flops or tennis shoes.
I also won't mow the lawn barefoot, or use a grinder without safety
glasses, or weld without goggles.
To do otherwise is shear stupidity.


And we aren't suggesting you don't. We are suggesting that you don't take chances you wouldn't take because you are wearing a helmet.

And as I stated earlier, only a TOTAL IDIOT would take extra chances
just because he's wearing a helmet (or a seatbelt in a car).
A helmet doesn't make you bullet-proof or immortal.

I still take all other sensible precautions when using tools too - not
depending on safety glasses to protect me from stupidity, but giving
my eyes a fighting chance in case carefull use of the tools still
sends something flying towards my eyes. Don't know about you, but I
can only blink SO fast - - -

Might as well give it up now. In this newsgroup those who oppose helmet use do so vehemently and will NEVER be persuaded that a helmet can help.

I had a few hardshell helmets back in the day. One of them I decided to get rid of. I took a hammer to it and it took quite a few very and I mean VERY hard s trikes to break the outer shell. I still have one of the iirc Vetta ones.

Thosde who want to will wear a helmet. Those who don't want to wear a helmet won't and will attack everyone who says a helmet can help.

Yeah, my god, another 1/4 pound on my 15 lb bike. That's almost 1 less
cheeseburger!

Technically, the chain tool is probably 20 grams as I would carry some
sort of tool anyway. g


I don't think that the question is "can" you carry a chain tool as much as SHOULD you carry a chain tool. I ride several bikes and they all have the flat kit and a spare tube and they all have a multitool. One of these multitools has a chain breaker on it. I don't expect to ever need it because I never have in the past 40 years. Or you could carry nothing more than a masterlink and a normal screwdriver and if you broke a link you could pry the other side off and insert the masterlink.


That would do. I think Joerg is a special case and could use a tool and some master links because he breaks chains. If you don't break chains . . .

I've broken a couple of chains because I messed up reassembly or, in one case, I had an odd shift on to the big ring and up-shift, and the quick-link snapped open. I probably side-loaded the chain in some odd way. I had no chain tool, but I was close enough to home that I could scooter until my wife came to pick me up.

I broke one chain in the middle of nowhere, but I was on tour and had a chain tool. Another mis-assembled chain broke on the way to work, but I was close enough to work to scooter the last bit, and then I bought a cheap chain tool at lunch. The bad part was dealing with a greasy chain in my backpack.

Indeed does Joerg appear to be a special case. However, if I experienced the number of problems/reakages that he does then I'd be carrying a pretty comprehensive repar kit with tools and parts that I'd most likely need. MAybe what Joerg needs to do is fix up a method of towing another bike behind the one that he rides and that way when one bike breaks something major he can then rather than having to walk 20+ miles back to civilization he could just ride the extra bike back and tow the werecked one behind it.

Cheers
