We need engineers, they make geologists look well-dressed.

How many watts is insignificant?. I would have to educate myself again [Hint: not going to happen] and go over the raw data to believe the Willits numbers posted way back, like I said, hundredths of...

Yes, I would say aerodynamics are big deal too, and they still matter, especially for the pros who are of course moving faster. And add to that, many miles of not climbing, but descending or flat (or...

My scenario in way goes counter to the laws of physics, what the hell are you refering to exactly?

Wow, just wow. You got me there, we all know how bicycle racers proceed shoulder to shoulder at a steady pace during a hill climb [Sarcasm alert].

Thank you for the kind words. Out of 38 people who started the course, two of us finished with "A"s, I was one of them. I did struggle with calculus, but I am able to utilize my modest understanding...

The Real World

Mister Hski, you have worked in F1, and thus you are one of the few people who I might envy. To be perfectly clear: I have a degree in a physical science (geology), a year of physics (only trig...

If I am reading it correctly, Willits is getting a savings of about 2.4% of 200 watts with both aero wheels? I thought the aero wheels would be dramatically better than 32 hole wheels. You guys must...

Sorry I mentioned it now, the only reference I have is elite level riders. I meant all of the numbers, aero numbers as well, I apoligize if I wasn't clear.

Oh, FFS, do you not see the guy slowing at the bottom of his pedal stroke? You are the one inventing here, HUMANS DO NOT PEDAL PERFECTLY 360 degrees, more so when stressed a bit climbing.

AND FURTHERMORE!!! (jk):lol: I think the Kraig Willet numbers, all of them, look too low. I have never used a power meter but have had a passing interest in power output, numbers and instrumentation.

My whole argument was about climbing on a 7% grade being faster on aero wheels. The work in the link is referring to a climb with a 16.8 mph average speed, and 1/100th of a watt? Probably beyond the...

So if I put 2,000 grams of water in my waterbottles before a climb it is no different than adding 1,000 grams of mass per rim?

Well there's the fly in the ointment, right there. Climbing on a 7% grade is faster on heavier aero wheels? Yeah, right, and I'm yur Irish uncle.
