Well you're going to undeservedly roast in hell for that statement.  Certainly
males turn much more aggresive behind the wheel of a car.  How else can one

This works. Solder doesn't work because it requires steel bolts soldered with
a LARGE iron and is a pain in the neck. There would be danger to the surrounding
alloy.

Wax is too soft.

Epoxy works just fine but can be picked out unless you do a good job
of it.

However, none of this works for wheels which is the original posting

There are several QR's on the market that have removeable handles. You
can still steal the wheels but it isn't justy giving them away.

Friction shifting is just fine.  I've never had
an opportunity to ride a bike with a high quality
index shifter, but since money is a major concern 
and I'm pretty rough on my bike, index shifters 
seem like a useless luxury.  It's simple to adjust
friction ( I don't know anything about index), and
I've simply never had any trouble with my chain jumping
gears or any of the other problems people associate
with friction shifters.  I guess the key is proper
maintenance (i.e. oil and adjustment)

I had lots of friction shifting bikes and they were pure unadulterated
crap! They wouldn't shift unless they jumped two gears at once. Then
they would shift by themselves because I'm partially deaf and can't hear
when I need to trim the shifter.

I switched to indexed and most of my problems disappeared. There is some
noise that I can hear on very quiet roads (just when I want complete silence).

Then I got a real deal on a Campagnolo Super Record grouppo and bought it and
installed it on my Peugeot PX-10. At first it wasn't all that hot since
I used the SR shifters but after I switched to Simplex shifters the thing
is a real dream. I can shift faster than an indexed system and I
can trim the thing by pedalling in reverse and watching to see if the
chain hops any and trimming it up. Then it runs silent as a cat.

So, I'm not going to trade in my Basso with DuraAce STI, but my Peugeot is
getting in lots of riding time too.

Petersen has previously made comments in the press (California Cyclist, within
the past year) that commuting is the real future of cycling. The way he stated
it I took it to mean "the most important future purpose of cycling." He himself
commutes 30 miles to work each way by bike. His comments to WSJ were no doubt
cynical--the number of actual bike commuters vs. the number of potential bike
commuters is extremely small, even in an area where it is easy to commute
by bike year round like the SF bay area, an area which is also becoming swamped
with automobile traffic.

I used to like it until I got tired and starting missing shifts.  Not to

An antecdotal counterexample. A friend of mine had a minor (he thought) 
verbal altercation with a motorist along the lines of "I've got a 
right to the road, too." The motorist then drove ahead a little way 
and got out of his car as my friend approached with a large wrench raised
in a threatening manner. My friend swerved to avoid the threat and hit
the side of a passing pickup truck. He fell breaking his collarbone and 
shoulder blade. The threatening motorist drove off and was never found.

The point isn't that there is a legion of drivers out there just waiting 
for an excuse to crush a cyclist. In fact, I think a lot of the posters
are overly paranoid in this respect. I doubt that this fellow had it in for
bicyclists in particular. The point is anytime you get in an
arguement (or exchange of gestures) with someone you don't know you take 
the risk that that person may react in an outrageous manner. If you're on 
a bike in traffic that reaction can have very serious consequences. 

Your behaviour can generate unreasonable responses and it is not bullshit 
to recognize that you are increasing your risk of injury by getting into
an exchange of this sort.

I have never actually biked Martha's Vineyard, but I did tour around the 
Island on a rented Moped back in 1986. I didn't find the traffic very bad, I 
think that this is probably partly due to lack of auto ferries departing
from Hyannis (I think the only way to get over there with a car is via 
the Wood's Hole ferries). I would suggest that you take care as the roads in 
some places are quite narrow and the lack of auto traffic is made up for by 
the large number of tour buses. It is beautiful place to bike ... but 
you might find it more enjoyable in the off-season.

Well, something like this happened to me once, but it had nothing
to do with provocation.  Pickup (why is it allways a pickup?)
drives up behind, slows down, matches my speed, starts to move
over onto the gravel shoulder.  Jam the brakes, rear wheel gets
air, I stop.  Guy finally realizes that I've stoped, stops the
truck, get out wih a bat.  I do a 180 and slowly move up the hill.
Guy yells at me and slowly follows.  Grab Ham radio (HT) and
dial freq. to make a phone patch to 911.  Guy gets back in truck and
drives off.  And I *STUPIDLY* didn't get the plate #....
The cops who took the report basically said "Well, this starts
to happen when spring rolls around.  Just somebody too bozed
up driving around.  It happened at 4pm....

Trickier.  Sometimes I just take the trailer along anyway, for the exercise.

Still working on this one.  Vetta used to have a lockable box which bolted
down to the rear rack, but apparently stopped making them some time ago.
I'll probably build something similar myself (18 ga. aluminum?).

I also dislike quick-release accessories; I took the QR off my seatpost and
substituted a regular bolt, and my lights are all custom-installed and bolted
in place.

Please don't spread these rumors. If you are doing well by the end of the
week it is because you have adjusted your riding style, not your fitness
at altitude.

I suffer from a potentially fatal altitude problem, so I looked into this stuff pretty closely.

Acclimatizing is caused by the body producing more red corpuscles. This takes
about 6 weeks for a normally healthy person. It can't be sped up except
with dangerous drugs.

All the mythology of acclimating after a couple of days is hooey.
