Time to take another stab at this

  This is a myth that has been hanging on for years and it deserves to be
trounced once and for all.  Heck they even tried extra heavy wheels to
smooth out accelerations and improve times for the olympics.

Supposidly cutting 200g of rotating weight caused this. From bikepower:
  8mi (12.8km) in 23:00 = 33.4 km/h --> 190 W
  8mi (12.8km) in 22:30 = 34.1 km/h --> 200 W

So we have a 5.2% increase in power to achieve the faster time.

Assuming the wheels are 800g (300g in tire + tube + 100 g spokes, 400g rim)
each and they are of a normal 700 c size that gives:
  44.6 J at 38 km/h (my TT pace) each

The energy in the total system mass is 4310 J.
  
Thus the wheels hold 1.8% of the total energy in the system and are responsible
for the equivalent of a 5% increase in power just by changing the total system
weight by 0.3% (assuming 170lb = 77.3 kg bike+rider).  Something seems really
fishy here.
  Wake up people.  Only 1.8% of the energy is in the rotating mass. It is 
COMPLETELY INSIGNIFICANT.  Even as far as the olympics is concerned they would
rather ADD 3lb to achieve better aerodynamics (on a kilo sprint) than cut that
much from the system.
  So why not get out on your bike and ride.  Wheel mass is even more
insignificant than "frame flex" and all those other lies that still exist.
Take this time of 22:30 for 8 miles.  That is about what I used to do when I
ITT'ed my MTB.  On my Klein I could do this in about 20:05 (judging by my 15km
ITT times).  Cat 2 people will do 8 mi in about 17:50 and some juniors I know
will do it in 17:10.  These guys usually ride on nice heavy 32c tires and put
all of the tri's who show up with dual disks to shame.  There is so much more
you can accomplish with proper training than you could by spending a few kilo
bucks on your bike and if you are looking at light wheels to accomplish
anything you are barking up the wrong tree.

I tried the Huarache and even ran a marathon in them.  The problem I found
(and others in rec.running) is the shoe is built for people with stable
feet - that is, the don't provide much support if you tend to overpronate
or land ackward.  I wouldn't recommend for someone who doesn't come from a
running background.  I have had to switch to a slightly heavier but more
stable shoe (Nike Skylon).

I do have to admit the Huarach is one of the most comfortable shoes I have
ever worn.  The back is actually a lycra-type material and conforms to your
ankle - it feels like you put on a sock.  I now try to look for shoes that
have the things I liked on the Huarache:

	- air or gel in the heel and under the ball of the foot (some
	  of the lower priced models only use air in the heel).
	- a good arch support to keep the tendon that runs through my
	  arch from having to overwork holding up my arch.

I think the best way to do this is to place the brake hoods on the rack,
as normal, then swing the back of the bike 90 degrees and bungee the rear
wheel on the rack also.  Sure, I might lose a couple of minutes in the
transition area, but heck, I have room to set up a small dresser, which is
infinitely neater than strewing clothes and shoes all over the place.

Has anyone out there correlated lipids with performance?

We've  discussed  diet etc., but even with a great diet  genetics can shoot
your lipids all to hell.

For example, if I eat like an angel I can get my total  cholesterol down to
about 170.  Eating like this really  sucks!  We're  talking  dry salads, no
cheese, etc.  etc.  etc.

If I'm "pretty careful" it rises to 190.  If I'm "lax" it gets to 215.  Now
the  definition  of "lax" is:  skim milk once a day, no fried food,  cheese
every other day,  crackers/chips  every  other day.  I bet my "lax" diet is
better than 95% of Americans!

Some folks will claim that, other than heart risks, performance will suffer
with high  cholesterol.  However,  I can't say that I've  really  noticed a
difference.  I'm stronger now than at the  beginning of last season, when I
was stronger than at the beginning of the season before that .  .  .

What about you?

Hi all,
The Oregon State University Triathlon Club is interested in competing with
other college tri clubs at races along the west coast of the USA.  Last
year, OSU raced (and beat handily, I might add ;-) the University of Oregon at
a local race whose director was persuaded to add a collegiate division. 
The race, the Heart of the Valley (HOTV) Triathlon in Corvallis, Oregon, has 
kept the collegiate division this year because it was so much fun.  The OSU
Tri Club, however, is hungry for even more.  Any college tri clubs out there
interested in meeting at races for friendly competetion?  If so, send me
email, or post, and I will carry the word to the tri club.

The Oregon State University Triathlon Club is a campus- and community-wide
club meant to bring people together for the fun of engaging in, or just being
part of, multisport competion and training.  The club consists of members 
whose abilities range from very experienced (Ironman and World's Toughest vets,
with some race and division winners) to beginners who are just starting out
in one or more of the 3 typical sports.

Your responses are ridiculous. 

There are several ideas for low cost alternatives to disk wheels that work 
at least as well as the "real thing" and are often better, for the reasons 
given above and also because they are lighter and can be used in a variety 
of terrain. I know of more than several national-level bicycle racers
(including myself) who have used homemade covers in all sorts of events. 

They are neither inadequate nor unsubstantial, and the only comical thing
is your attitude.

I think the distances used for the Olympic distance race were picked
because they are standard distances used by the individual sports:

	1.5K swim	= swimmer's mile in competition.
	40K bike	= National individual time trial distance.
	10K run		= 10K's everywhere!  Major track event.

Triathlete Today did a good article on comparing the individual events
and the amount of time that could be gained/lost by top and middle-of-
the-pack triathletes.  They found the times to be comparable for each
event.  That is, if the top swimmers had split times 5 minutes faster
slower swimmers (for comparable groups, elite vs, elite, and so on), then
the top bikers and runner would be gaining 5 minutes on the slower
bikers and runners.  They found the Olympic distance to be fair in that
respect.  The problem these days is that people like Mike Pigg are
the very good athletes in all three events.  They minimize their loses
and capitalize on their gains (maybe they should go into the stock
market).

Personally, give me a short swim and a long bike!

Are you joking?!?  By what criteria do you judge what is inadequate or
unsubstantial?  As far as the air is concerned, it doesn't care whether 
it runs into fiberglass or plastic or metal spokes, it just generates 
different amonts of resistance.  If a plastic cover works as well or better
than a "real" disk why spend the money???
BTW, I've been using this type of cover for several months and it works 
great.  I got about 700 miles out of my first effort and finished several
bicycle road races on it.

Bicycle weight reduction - my final comments...

After sparking considerable commentary with my original posting of reducing
weight on a bicycle (especially rotating parts), I have come to the following
conclusions after reading the replies:


	 Most important: 
			 training
		^	 aerodynamics
		|	 frame stiffness 
		|	 cycling technique
		|	 bicycle maintenance
		v	 weight	
		
	 Least important:


	I still feel that weight reduction cannot hurt, but, if it IS done, it
should be done to a point that does not compromise bicycle integrity/
reliability or the attention given to the more important factors. 


	Thanks for all of the thoughts on this topic!!!



	Off to the roads on my Schwinn Varsity...  
	I'll show 'em all!!!
