Who needs a TT helmet?

Not Devon Vigus, who just won the Mt. Hood prologue:
http://www.cyclingnews.com/photos.ph...071/CYC-MHP061

He beat all the favorites by 12 seconds and more.

It also sort of looks like he is on a round tube bike set up as a TT bike, with 50mm or so deep wheels.

The prologue was only 3 miles, but his average speed was over 30 mph - aerodynamics play a pretty big role at those speeds.

Yeah, but if he had a TT helmet and aero tubing he would have won by 12.83 seconds!

I saw that. He averaged 30.8 mph without a TT helmet or a disc, wow that's cool!

From cyclingnews: "O'Neill and his teammates were understandably shocked, even thinking that maybe it was a error in calculation. "I averaged 518 watts and he beat me by twelve seconds," said a stunned O'Neill. "I was spinning in my 58x11 for half the course!" But the time stood."

518 watts & 58 x 11, yikes!

Most prologues that short are won by sprinters, its just all about putting out tons of power for those 6 minutes or however long it took him to do 3 miles.

No one spins in a 58x11, unless it's on a pretty severe downhill.

110 RPM on a 58x11 is ~45 MPH, assuming 700c wheels. That might be an incorrect assumption.

The course was hilly, so I guess he was spinning out on the downhills. It was also probably a bit of an exageration.

But not with 200c wheels.

Apparently there was an error in the results and his time was off by a minute. He's been relegated to 65th place. I guess that TT stuff is important.

Can anyone estimate how much time gain he would have had over a 3 mile course with better aerodynamics (TT helmet, TT bike, disc wheel, etc)?

There is an apt adage in the aeronautical engineering field: "With enough thrust you can make a brick fly".

Sorry, 58/11 is 142 inches?!? You cannot spin that gear out unless you are motorpaced.
