Yes, you've just proven conclusively how little you know about
practical aerodynamics.


As opposed to the real thing, I presume. BTW, you might read
_Bicycle Science_ for a short introduction.


Yeah, if there's one comprehensive handbook on aerodynamics it's without a
doubt Bicycle Science.

Carry on, Bill. You're fun to watch!


You've proven once again that you'll resort to mindless rhetoric,
which seems to be all you are capable of. Where you perchance fool
enough to vote for Bush?

Given the number of careers you've claimed to have, Tommy, I really
don't believe you.


Why that just devastates me Bill. But then again, I'm not frightened to
death that other's might find out who I am that I am shaking with fear that
someone else might so much as discover what sort of HELMET I wear!

Perhaps you'd care to explain Section 21212(c) of the California
Vehicle Code which says, "No person shall sell, or offer for sale, for
use by an operator or passenger of a bicycle, nonmotorized scooter,
skateboard, or in-line or roller skates any safety helmet which is not
of a type meeting requirements established by this section." That
section refers to standards set by the ASTM or the U.S. CPSC. Both
supercede the ANSI standard which expired in 1994. If you check
http://www.bhsi.org/stdcomp.htm, you'll find that "In May, 1995, the
ANSI Z90.4 committee voted to adopt the ASTM standard as its own to
replace the 1984 version, reflecting the movement of active standards
development to ASTM." http://www.bhsi.org/cpscfinl.htm has the CPSC
standard.


What is there about the term - "self certified" that you don't understand?

Well, Steve, it is interesting that you are blaming me when these other
guys are posting nothing but a string of baseless personal attacks.


Why don't you call him a liar while you're at it?

A V1 Pro has vents. Mine does too, plus having a more aerodyanmic

THen you haven't looked very hard. A V1 Pro was first sold in 1983.
See http://www.bellbikehelmets.com/main/about/timeline.html, which
BTW has a picture of it. Modern helmets have an assymetric design,
which fills in the area behind the head. A Bell V1 Pro is
symmetric or very close - not at all "teardrop" shaped.


Let me guess - you have one of those genetic diseases that cause you to
forget anything before the last posting?


Let me guess. You are still acting like a child and trying to hide the
fact that the picture discredits your claims.

It is humorous though to watch someone as ignorant as yourself tell us that
you can determine areodynamics by having some crude ideas gotten by magazine
articles on the subject but those with actual wind tunnel experience in the
speed regimes pertinent have to somehow have published papers on precisely
the helmet that you're wearing before their opinions are valid. And of
course you won't actually SAY what your helmet is.


Previously you've claimed to be an electronics something or other, a
professional writer, and Lord knows what else. Interestingly, you
always seem to claim to have the precise skill set to match what you
are ranting about at the moment. Sorry Tommy, I'm not impressed, and
won't believe you without proof, particularly after all your lies on
various topics. And besids, your've never said exactly what your
alledged "wind tunnel experience" is (but I do recall something about
10 hours, which isn't a lot.) Did you solve the Navier Stokes
Equation or merely fill some canister with oil?

You're the one claiming that your helmet somehow is more aerodynamic than a
Bell X1 Pro. We're the one's laughing in your face since you don't have a
clue what you're talking about. "Teardrop" shaped indeed!

Back to your junior high school locker room?

If you think the shape of a typical bike helmet allows the airflow to
smoothly converge behind the helmet, you must know very, very little
about practical aerodynamics.


It has to reduce drag relative to a completely symmetric helmet, and
not by very much.


Bill, you really are a nutcase aren't you? You haven't even a rudimentary
understanding of linear flow aerodynamics and every word from your brain
makes that more apparent.


The term you probably want is "laminar flow". Your confusion is yet more
proof that you really don't have a clue. And your continued bad manners
is just another indication of your pathetic abusive personality.

I'll treat you as I did Guy and flush the rest of your messages from
today. Come back when you can act like an adult.

Sorry about that Bill. Zaumen has reached the penacular heights of
foolishness and I just HAVE to see how far he will take it.

Are both of you little boys having fun in your crib? What a bunch
of mindless infants the lot of you are!
