Interesting note about the Fignon-Lemond TT stage. I was working for Mavic at the time and they were component sponsors for Lemond's ADR team (including bars and stems). Before the TT, Jose de Cauwer (Lemond's DS) had to ask Mavic for permission to use the Scott bars. Mavic could have gone either way but agreed to let Lemond use the bars. The rest is cycling history.
That’s what I want to know. I get the drag being proportional to the square of apparent velocity; I don’t get why it then requires a velocity cubed relationship to overcome that drag. Explain it to me like I was a B/C student in college physics 40 years ago.
They were not illegal, the 7-11 team used them earlier that year at the Tour de Trump (later called Tour du Pont). Greg and other riders also used them in earlier time trials in stages 5 and 15. They were available to Fignon and he chose not to use them.
Hi Josh, when you mention the 8 sec pencil, I suppose it would heavily (non-linearly) depend on the placement of the it. So, would it refer to a pencil close to the headtube, like a cable housing, or sticking away from the rider+bicycle front profile? And how different would it be then?
Joao, such a great question!! Yes, the pencil would have to be in clean air to make the 8 seconds in 20k. There will be reduction effects when something is directly in front of or behind another element, but these effects can be quite small, so this same length of cable housing passing in front of the head tube might change the number to 7.5 seconds.. but since the front of the bike is mostly penetrating clean air the magnitudes are still high. The same amount of housing connecting the rear brake from an internal TT routing, might only have 1/2 to 2/3 the penalty.
@@SILCAVelo Thanks for you so comprehensive explanation! I never thought the difference was so small between those two. I feel like Contador for a moment
Actually, there are 10 kinds of people in the world: those who know this is a binary joke, those who don't, AND those who know this is actually a tertiary joke!!

This is why I always keep a fan behind me on zwift. Tricks the aero to think I'm going significantly slower.

I amused by his t shirt showing bikes on top of his BMW hanging out in the wind crating massive aero drag.
12.25: "The power goes up with the cube of the speed". Why is that, as in... why is it not directly proportional to the drag?

@@MB_MN_19 Because you're going faster at the same time and that also requires more power in the same time.
@SILCA Velo Weren't tri-bars illegal under UCI rules at that time?
