The universe is sometimes made foolish by people doing stupid stuff.
Like the guy way out in the boonies in Yosemite Park. Laying on the
ground off the trail in the bushes, saw him just by chance. He was
already delirious. He had made that trek without carrying any water, no
food, and barefoot (no shoes!). The only words he was able to mutter was
that he wanted to die. Well, we didn't let that happen.

Which is hy mose of us carry a small tool repair kit that
includes a chain-breaker. That way a broken chain isn't an
ememrgency and a repair only takes a few seconds. After all
seconds count when you're beig stalked by mountain lions or other
hungry critters doesn't it? For someone who either breaks chains
a lot or often comes across people with a broken chain (bother
very rare where I ride even on the technical trails) it ONLY
makes sense to have a chain breaker and spare link(s)and
quick-link WITH YOU.

To be honest using a rock and rusty nail to repair a chain in the
field sounds like something an armchair bicyclist would think up.
Such a repaired chain would most likely fail again after only a
short distance. Believe it or not there's good reasons why chain
breakers are used to fix a chain.

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.


You never had a chain suck resulting in a pretzeled or corkscrewed
chain? Then you probably haven't ridden much singletrack. Sometimes the
worst part of the "pretzeling" has to be surgically removed in the
field, upon which the chain is rather short but at least one can get
home without having to hoof it.

Even though I ride offroad 50% of the time it happens so rarely that I
don't see an urgency in adding a chain breaker to my on-board kit.
Besides, you need to find some rocks anyhow because the rest of the
chain usually needs straightening so it passes the derailer hanger
without an awful grinding noise every time.

A chain breaker is one of the tools easily improvised. The "McGyver
Deluxe Edition" consists of a pin (used to punch out the chain pin), a
nut or sawed off little chunk of pipe slightly larger and long enough,
and some stiff wire. The end of the wire gets fashioned into a loop that
holds the pin well. That is best done before placing it in the tool kit.
Just roll it 2-3 times around a drill bit shaft slightly smaller than
the pin. The wire can also be used to tie stuff that came off. Brake
lines and such.

Now a storm of outrage will likely break loose on this NG because this
McGyver tool ... gasp ... doesn't even have a flashing LED.

In the olden days road bike chains didn't come with missing links. The
only way to take them off was to punch out a pin. I have changed lots of
chains just using pin, nut and hammer. I don't know how I made it into
my 50's without a chain breaker but somehow I did.


... 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.


It's more for mountain bikers. I have my tools in a waist pack. That
also contains cell phone, keys, wallet, pencil and, yes, no kidding, a
small leash. That leash has helped bring some dogs home over the years.
The road bike also has a towing rope in the bottom of the left pannier.

MTB and road bike have identical panniers (Nashbar Daytrekker) and I can
simply pull the waist pack out of one bike and slide it into the other
in seconds if I decide to switch. This also avoids the worst case
scenario where you find a nice brewpub and then discover that you left
the wallet in the other bike.

Jay - You couldn't be suggesting that you let a friend die rather than try anything because it is usually ineffective in the long run?

You're conflating allowing a person to die with refusing to break ribs on a dead person. I did CPR on a lot of dead people who remained so. I had little or no expectation of a positive outcome in many cases -- but there was at least some chance in my opinion. My partner or I could always pronounce death, which we did on occasion -- usually when someone was way gone or in pieces.

Even if we started CPR and transported, some doctors were more "realistic" than others and were quicker to pronounce death. Some doctors would shock a corps because they wanted the practice -- one bad hospital comes to mind. And of course, some people did come back, but I wasn't privy to their long-term outcomes. NOBODY just sat up in the back of the ambulance and shook it off, like on T.V. Most of the people who came back coded first in the ER or had witnessed heart attacks near a fire station or near someone who started CPR and who were also close to a (good) hospital.

But to your point: if I found someone collapsed on a trail twenty miles from the nearest town -- pupils fixed and dilated, no pulse, no respiration, cool to the touch and cement-colored with dried drool at the corner of his mouth, no, I would not start compressions.

Hint: A repetitive scraping noise is usually a sign of imminent wear-out
of some part. A derailer hanger coming apart on the 20mi home isn't so
cool because that means hoofing the remaining miles.

As unbelievable as it may sound I tend to invest that extra minute or
two to prevent such things.

I still don't follow any of this. I rode Mt. Bikes since they were first developed. I've ridden road bikes roughly forever. The chains that I've seen break didn't break - they popped one side of a link loose. And this was because they weren't assembled properly. I see no requirements for a chain breaker. And I haven't been disappointed by not having one.

This time around you're suggesting that we should try to revive dead people.. We both know that cardiac arrest is not treatable after a minute or so, and that if you don't see a person having that arrest treating him is close to impossible. But if you so see a person have that arrest you must treat him. I didn't know how to do CPR and watched my good friend die. It wasn't pretty.

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?
