always get what you always got"
Yeah -- that works for me.

Not to be an alarmist, but your site makes no mention of liability or
insurance.
Years after you work on a bike, you can still be sued for something you
did or didn't do, or for installing a part that failed through no fault
of yours. Years after you sell a used bike, you can be sued for an
aftermarket part that was already there when you got the bike, or an OEM
part that someone before you removed.
If you live in judgement-proof poverty with no home to lose and no
income to worry about, then your only liability concern is a moral one:
will you be able to live with yourself if you make a mistake and cripple
someone?
But if you do have assets or income that would be worth the time of a
plaintiff's attorney, you should make sure you have insurance for your
liability exposure.

I'd say this is a bit of an over-simplification.
Lower than maximum pressure is more comfortable, and it depends on the
weight of the rider. You can still get enough pressure to avoid pinch flats
without getting up to the maximum.

My tires were quickly getting punctures and cuts at their 120psi max.
Dropping to 110 psi fixed that. Soft race tires and I'm 85 kg.
I'd say it depends.

Dear Aeek,
Testing shows that higher pressure does indeed lead to more cuts and
punctures:

With more pressure, the tire presses down harder locally on sharp
debris.

BAH. I'm now going to worry about losing the house every time I touch
one of the neighborhood kids' bike for them. Last time I went to fix
one, both wheels were on hand tight. An elementry schoolers hand tight
at that. Still, I don't know that I'll be able to turn them away when
they're standing there with a minor break or flat that's going to keep
them from riding around with the rest of their friends.

If you're just occasionally helping the neighbor kids for free, you're
at a very small risk. First, you aren't presenting yourself as a
professional bicycle mechanic, you're just a friendly neighbor. Second,
the chances are good that your friendly amateur assistance is covered by
the personal liability coverage of your homeowners or renters insurance.
(Read your own policy for its liability coverage and exclusions.)
What concerned me about the original posting is that the site goes to
some lengths describing aspects of running a bicycle repair *business*,
without ever mentioning the liability aspects of owning a business.
Once you present yourself as an expert and charge money for the work,
you're in an entirely different legal environment than when you're being
a friendly neighbor.

Yes. And now he's a desperate lameass googlewhore. And from my email
conversations with him he thinks he's providing something worthwhile
rather than spam.

That link gave me a Carl Fogel post about Subaru cables.

Dear Frank,
The link could be just a typo.
But it might be an example of the problem of the lost Google posts
noticed earlier by Ron Ruff and Ben C. from October 2006 through
January 2007:
http://groups.google.com/group/rec.bicycles.tech/msg/3e30dc3d0e41731f
I was able to see more posts than Ron and Ben could, but I'm beginning
to suspect that I can't see everything.
When I click on my profile for the posts for October 2006, for
example, Google claims 276 posts for the month:
But when you click on the 276 for October, the search finds only 127
posts:
And if you try to browse through the 127 "found" posts, only 45 posts
are actually available:
I can't find the thread by searching, and my raw list of October posts
simply vanish long before that date.
Anyway, the test consisted of pumping a tire up to 30 psi and rolling
it back and forth with heavy pressure on a nail sticking up a little
from a vise, looking for punctures, and then repeating after raising
the pressure 10 psi.
Obviously, the tire will "tent" over the nail-point until the pressure
is high enough to puncture the tire.
Looking through my files, I found the pictures, dated 10-26-2007 and
10-27-2007.
At 100 psi, as I recall, there were sounds and the nail finally made
holes in the tire tread, but the holes didn't go through. Probably the
nail broke through the outer rubber tread, but then was stopped by the
internal Kevlar belt.
At 110 psi, there were sounds again and the nail broke all the way
through the tire, leaving a hole on the inside.
When the nail broke through the tire at 110 psi, the inner tube
"tented" and the nail left a faint but visible dent in the tube.
Here's the setup, with a nail in the vise with a spoke ruler, a Presta
valve cap, and an identical nail showing the point:
http://i11.tinypic.com/2hp6136.jpg
In the next two pictures, a third toothpick points to the very faint
dent where the inner tube "tented" over nail point.
Here, toothpicks show holes in the tire tread at 100 and 110 psi:
http://i1.tinypic.com/2n08xlg.jpg
But only the 110 psi hole goes all the way through the tire to dent
the inner tube:
http://i11.tinypic.com/4dg3jg1.jpg
The faint dent in the inner tube is clearer in the first picture.

pictures.
If the original posts are lost, I console myself that half of
Shakespeare's plays only appeared in print seven year years after his
death when his friends collected them in the First Folio of 1623.
If it turns out that I just made a typo that leads to the wrong post,
I console myself that (among many other typos) page 399 of the First
Folio was mistakenly set as page 993:
http://dewey.library.upenn.edu/sceti/printedbooksNew/index.cfm?TextID=firstfolio&PagePosition=906
Left-click on the upper right corner of the scan to see the infamous
typo.
