How long before the UCI bans wheels that have "negative drag"?

Wow, if I can get a frame that planes and some wheels with negative drag, I won't have to pedal at all!

[LegendRider]

Good point.

Can you imagine how many of those wheels they'll sell to triathletes???

Does anyone know the ownership structure for Zipp? Assuming they're a closely-held private company, I'll bet the owners are doing OK.

What about the anti-gravity paint I've been working on in my basement?

I hope they don't ban that once I have it perfected...

its probably in the attic by now.

Laughed my ... off at that.

Minus 80 grams drag, so roughly 11 watts forward power!


presumably the faster i go, the more watts it creates ... so at some speed it will create more watts than i ruin with my far arse ... it will be a perpetual motion machine. someone call newton, physics is a hoax!

the less effort you put in the faster you will go...
i want that man.
the more effort i put in the slower i go...
ill pay anything...i have swoops credit card...

Perpetual motion, phtttttt! You'll be going so fast your headlight will no longer work!

pluse they sell their 2nd's to smaller co. and then they are relabled
cheers

remember when a telecom mechanic put ullrichs 4 spoke aero front wheel on backwards for a tt?
flippin hilarious.
it cost him 20 seconds instead of saving him 30 seconds and he lost the tt by maybe 10 seconds or something.

perfect.

i heard that the guy was now bruce k's personal mechanic...
"hey bruce, the chain is on the wrong side on this bike man... isnt it supposed to go over the thing with the teeth?"

someone call newton, physics is a hoax!To impress Newton, you could try this approach on your next custom bike.
Think how it would feel to go uphill into the wind without pedaling. :cool:

P.S. – Would be so slow as to require at least a trike to stay upright, but it should work.

All we have to do is figure out that gravity thing and tire friction and we won't be pedaling. :)

P.S. – Would be so slow as to require at least a trike to stay upright, but it should work.That sail would spoil the classic lines of my next custom bike, and the tacking required would be really disruptive in pacelines. Guess I'm doomed to keep pedaling...

Mr. Newton has no reason to worry. Negative drag is quite common--think of a sailboat. The energy input to the bike is being extracted from the wind. I believe this is a factor that affects some faired recumbents.

wings, airplane blades, helicopter blades, sails, probably this wheel ... bernoulli's principle. i was joking about calling newton. no one is busting the gates of football physics.
