Tom is using K (1,000) instead of km (1) by mistake.

You and Frank have a lot in common. The last time you rode was down to
the store and back. For another pack of cigarettes.

I've refrained from replying to many of your rantings but...

You are absolutely hilarious with your misconceptions, your errors and
your plain lack of knowledge in so many topics you post about.

For your information, not that I need to provide, I've never smoked a
cigarette or tried smoking one in my entire life. You sir, are completely delusional.

Cheers


But Sir! it is so difficult to insult someone if one is restricted to
telling the truth.

Not always.


Well, yes. There are those who resent the truth being told about them
:-)

That means that the lead rider is making about 426 watts and there is a rotation of only 8 riders so you don't
have that much time off of the front.


Let's assume there are really only 8 riders in the front for 2
hours. So 1/8th of the time the rider produces 426W (as you
calculated) and 7/8th of the time he drafts which means about 30%
less effort, i.e., about 300W.
Now do the math and you see that the average is way below 400W.

The hour record requires about 440-460W for one hour -- if you
think any pro cyclist can hold 400W for two hours then please
post _real_ data, not your guesstimates...

Here's one example:
In the 2015 Tour De France won by Chris Froome. He made his mark
on Stage 10 during the the climb to La-Pierre-Saint-Martin, where
Froome took the lead "It's about a 15.3 km climb," said Kerrison.
"Around 41.30 mins. Chris's average for the whole climb was 414w,
and a VAM of 1602 Vm/h."

But isn't the stock market essentially you, the share holder, betting

Or alternately loaning an entity money in the hope that he would

The UCI or Olympic 100km mens team time trial, the average speed is
approximately 50km/h, so 2 hours with 4 fresh riders, not fatigued by
weeks of racing a grand tour.

bikecalculator.com suggests the power required is 430 W using aero bars
and tubulars.

1/4 of the time a rider must produce 430 W, and 300 W for 3/4 of the time.

I think the average is just over 330 W.

The courses are generally relatively flat, so slightly heavier and more
powerful riders are chosen to compete. Less reliance on power to weight
ratio.

The UCI individual time trial requires an effort of about 50km/h for up
to an hour, so 430 W continuous for 1 hour, similar to the hour record.

It's more like betting that the stock price will rise or fall unrelated to the book value of a company or its earnings/balance sheet. We know this from the dot-com bust. https://investor.uber.com/news-event...s/default.aspx Gee, just a $5.2 billion loss. Buy Uber!

Your delusions began when you started considering yourself some sort of expert at anything. What have you done for a living since your replies seem to indicate that it was something like ditch digging or hod carrying.

I would have to do some calculations on that since time trial bikes have significantly less resistance and hence require less power to carry speed.

Never the less, you get a fairly accurate picture of power output with weight, frontal area (including estimated drag factor) and time over distance. The accuracy of this rivals a power meter.

As I pointed out, there really is no use for a power meter on a sports bike other than to brag about your power output. Chris Froome has already stated that he uses if to keep his own power output within his physical limits and not to measure top power output.

Jay, investing in an unknown commodity is indeed a bet. Indeed that was the dot-com bust. Why would people invest in companies whose product is information when you don't know what that information is worth?

Are you suggesting that the Chinese have purchased Smithfield Foods, Motorola and GE as a BET?
