Don't worry about the plumbing.  The heart and lungs cannot supply a
sufficient supply of fresh oxygenated blood and nutrients to the muscles
and as long as the muscles are flexed venal flow is stopped.  Masseurs
exercise venal blood flow that can take place without any muscular action.
When you sleep, the body automatically makes you turn and flex muscles for
veal flow to make up for your inactivity.

Many athletes have natural micro twitches that ripple through the muscles
any time there is no major muscular activity. As I recall it is called
"fisiculation" or the like, I don't have a medical dictionary handy.

As I mentioned earlier, I would like to hear what results and insights the
pulsed pedaling experiment yields.  I think this exercise is interesting
and may help clarify the issues at hand.  That each muscle has it's overhead
comes into play here as well.  Extracting work from a muscle has its basic
losses and some of these may remain relatively constant as the demand on
that muscle increases.  This is what I mean with loss of efficiency by
distributed muscle sharing of a task that can be done with fewer muscles.

Well, all I can say is:
If any cyclist needs to shave his legs (women excluded, since leg hair is not
very womenly (I don't need any flames from jock-like liberation girls, thank you
))  is a wimp.   The "drag" caused by leg hair is minuscule... Maybe before you
ride in a sprint race... But still thats pushing it.  If you're tough, just live
with it and learn to over come it (oh boy, just think how fast you could go if
you rode without shaving your legs and then shaved them!  Maybe .01kph faster!!)

[ stuff about pedal strokes ]

There have been studies done of racing cyclists where pressure
sensors have been mounted at various places on the pedal and
toe strap.  It turns out that there is no significant upwards
component to the pedal stroke.  Check "Bicycling Science" for
one such study and a list of references.  Often the cyclist
feels like there is, but I think the best that usually happens
is that the unweight the pedal a little on the upstroke.
(This can easily be mistaken for an upward force).

I certainly believe this from my own riding.  I have tried
experimenting with "ankling" techniques and various other
things, and while they provide some novelty value, I haven't seen
any improvements from them in speed or endurance.  (If anything,
I see just the opposite effect).  I just let my pedal stroke
do whatever it naturally does and don't try to force it into
some predefined mold.

As always, your milage may vary.  There are also the psychosomatic
effects, which can be real.  (Ie, if you believe it makes you
faster, then it might, even if there is no physical basis for
it).

	Living in Iowa, we tend to have barnyard-type animals frolicking
in the road and being terribly annoying.  Anyway, my dad tells me of
the time when hogs carried a lot more fat than they do today, and when
a sow might weigh 900 punds or better.  He had one such sow, and she
liked to lie in the muddy ditches next to the rural highway.  When
you've a critter weighing 900lbs and sporting four-foot drive, a
fence won't hold them unless they _agree_ to be held.  She didn't.

	One fine day she was crossing the highway when a '64 Fairlane
(or was it a Falcon?) popped over the hill and hit her square on.  The
hog survived, and lived another six years with a perfect imprint of
a '64 Fairlane grill scarred into her side.  The car was totalled.

I have a seperate source to back this up.  In high school (10 years ago?)
we were shown a film about motorcycle safety.  It stated that motorcycle
police officers were less likely to be in an accident.  I believe the
number was in the 75% range.  That is, the average distance travelled
between accidents for cars was 75% of that for motorcycles.  The data
was from a large municipal police force (Toronto?).

You would be surprised how inexpensively a bike shop can make this
custom for you.  Have them take an inexpensive lightweight bike and
have them change the rear wheel to a single speed type.  Let the
derailleurs come off.  The bike shop will be able to put on a single
speed freewheel or a coaster brake hub.  If they use the latter, they
can remove the rear caliper brake.  They should be willing to do this
for the difference in retail cost of the parts, which should be
negative, plus labor.  The net price should be approximately the
original price of the bike before the modifications.

While they are at it, they can change the handlebars to the upright
type, if your friend prefers those.  While she's at it, have them add
fenders, a chainguard, and a skirt guard.

I think that since they are going to do this much, they may as well go
all the way and use a coaster brake instead of a single speed
freewheel.  (This is an aesthetic consideration.)

I'm not taking issue with the claim that bicycles can cause serious and
expensive damage to cars -- more often by causing a car to hit something
else than by running into the car, I suspect.

But in California the situation you described does not necessarily mean
that the cyclist was at fault.  If he entered the intersection legally --
that is, if the light was green or had turned yellow before he could stop --
then you (and the bus) are required to wait for him to clear the intersection
before entering it -- regardless of the color of the light at the time.

I am frequently in the position of the cyclist as you described it.  Many
lights where minor streets cross major avenues have very short minimum
lights for cross traffic.  So if I am the only vehicle on the cross street
and trip the light, the light will be red by the time I am half way across.
So far I've found that traffic departments will increase the minimum time
when asked -- perhaps because they would be largely at fault if there were
ever an accident.

(BTW: I'm not suggesting that you *were* at fault in the accident.  You just
didn't describe the situation fully enough for a California audience.)

Two (2) Brigestone Mountain Bikes Stolen from Pittsburgh, PA's Carnegie
Mellon University!!!

A red MB-4 55cm 1991 model

A green MB-5 49cm 1991 model

Both of these bikes were stolen from a bike rack and had been locked
with a Kryptonite U-lock!

Unfortunately, the jerks didn't even leave the broken locks so it is
doubtful that Kryptonite's guarentee will help.

These bikes were purchased in August last year and were in very good
condition.  They were both registered with the national bike registry. 
The green bike had only minimal wear (ridden less than 10 times).

The owners of these bikes are both college students with <<NO>> income
during the school year so buying a new bike is out of the question. 
Please keep eyes and ears open for used bikes fitting the descriptions.  

Any suggestions would be greatly appreciated.  I loved my bike and feel
very violated.

to see if anybody out there knows anything about the Campy lines
within the last 6-7 years.  I was told that the components that I
