top speed play

A question prompted by the 50-mph leadout thread. Smack me if it's a faq.

My meager top speed on a bike is 56.2 mph, which I hit riding alone down the back of the Parley's
Summit frontage road on a very windy day. I spun out my 52/12 then tucked.

I know I can spin pedals fast enough to achieve that speed at that gear, but not necessarily under
load. Is it more likely that I pedalled to my top speed or achieved it by slimming my frontal area
after spinning the gear out?

Man,

that was a frequently asked question?

I emphatically state that the only thing you did to get to 56.5 mph was choose the correct hill.

So then, why doesn't everybody that rides this hill reach 56.5 mph?

LOL. Okay, the could-be-a-faq is: Does speed typically increase after tucking? Never mind, it's a
stupid question whose answer is, if the hill and wind are "correct," yes. As you were.

I understand. So as soon as an old lady comes along with the right weight/drag coefficient she
will immediately hit 56.5 mph. Cool eh. Wish I had one of those hills at home, for climbing
practise of course.

Hey dork,

If you could pedal your way to anywhere close to 56.5, we would be reading about you in
cyclingnews.com.

Amateur cyclists are hard-pressed to top 35mph unaided by wind or slope.

Never said you'd read anything about me. You may already have read about old ladies though.

Why do you call me a dork just because I don't know everything that you do, or think you do maybe?

Did it yesterday, but with wind. However, it *was* with cadence 132 (and out of the saddle) so no
way 130+ is "spun out" (re. some other thread). Ah well never mind.

Your speed kicked WAY up after you tucked. There's no way that you could hit 50 mph and be pedaling.
In the first place that is about 150 rpm and very few people can make power at that speed. So you
probably pedaled up to about 46 or so mph and then gained another 10 mph in your tuck.

In the 53x12.5 yes. I think I can pedal to about 140 rpm, but very few Alpine descents allow for
that speed with the 53x11.

Seems like a reasonable guess, yes.

I bet you're not an amateur then.

WTF are you implying. I regularly outsprint Michael Boogerd.

I've heard it said that people perceive the world around them based on their own state of
consciousness.

The question was about the contribution to pedaling on a steep hill.

Regarding the OP, I have a hill where I live that if I coast I'll hit 38 mph and if I pedal as fast
as I can I'll hit 45 mph. The hill that I can hit 50+ on requires no pedaling.

It's possible to hit 50+ mph while pedaling. I do it all the time motorpacing behind my dad's van. .
and thats in a 53X12. Granted I am spinning my ass off, but it is possible

I can coast to that speed down a hill. Pedalling has nothing to do with it.

You can only do it because you're in the aerodynamic dead zone. On a straight hill pedaling over 42
or 43 mph makes more air resistance than power.
