you can do this by yourself if you hava a powermeter. just find a quiet road thats a straight line and at least 3-5km long and go back and forth a few times and put the data into a formular. then repeat the same day with different setup and gear and you will get pretty good results. also apps like „mywindsock“ can help. that way I came down to roughly 0.21 on my roadbike with aero bars.

What lab?

Figure of speech. Not a physical lab. Same way basketball players say “in the lab” when they mean they’re on a basketball court 🤷🏻‍♂️

But he dropped the UNDOUBTEDLY though. 😂

I will say that before 2016 is purely because of Lion's luck. I think at that time most people are not be aware of how important aerodynamic is. So right now bar is getting higher so all those testing I think has its value. Also interesting if it has all those all set up and put them together as a new test and to see how the results looks like. It's going to be really interesting.

So here we are talking about the air dynamics. It's more like finding the lion's body position to reduce drag. Also, he's fighting for, you know, when you change your body position, your ability to generate a certain power is going to be changed. So it's about finding that balance.

Undoubtedly.

Exactly. I have friends who are huge fans of high hands and I always point to Jan as an example showing it's really more complex than we think.

Yeah, I agree. Actually, you can combine them together. You have high hands, you have neck to flat hands, and also you have those crazy helmet. I believe for a certain body's position, sometimes you're going to have positive impact on your aerodynamic using a type of helmet. Under a given body position, but it might change if you're doing different, let's say, the environment. So if you're more flat, you're one direction, your angle, if you're considering to the scenario, it's a lot of things you can play with.

It's all from Quick Step....

Good question!!

Mysteries of the world

I think he said he didn't want to go outside of his comfort zone and travel there. Note that Laura, Patrick and Jan are all Germans.

@@jank4809 Chelsea has been here and Kat as well when they were picked up as athletes. I would even assume Lionel is so high profile they would send someone to the US for him.

He said Canyon offered him that service. Maybe he's a conspiracy theorist and thinks they won't give him the best aero fit. At this point I have no idea why he's not taken them up on this offer. Also someone mentioned he didn't want to be out of his comfort zone (Mr. No Limits 🤦‍♂️) , but fact is he went to the European Championships so could have just popped in after that race for testing. Again why he chose not to do that, when he said he needed aero testing only he, his wife and maybe Talbot know.

Uci limits the tilt. There isn’t the restriction in triathlon

yes, he used a PN 3.1 (I think). His reach was extended and he tried to rotate his pelvis a bit. He was previously angled a bit over 25 deg (probably 27) and moved to 15. His hands were also positioned differently. So there was more than just angle going on, but that was the bulk of it.

@@marcgraveline1771 Thanks for replying! Despite being open about how often he has changed his position one thing he has not talked about is how often he has changed his saddle. I think on the Canyon we've seen him use the PN 3.0/3.1, bisaddle, a fizik saddle of some kind, the geobiomized saddle and now back to the PN. Would be interesting to know what Lionel has liked and disliked about these saddles and how it has maybe influenced some of the position changes and ultimately his cda, as I would think hip rotation is going to play a big role in how good of a position he can get himself into. I notice the saddle is slammed all the way back suggesting he's trying to really ride off the front and relieve soft tissue pressure? There might be another saddle he hasn't tried that would help with this.

As far as from public knowledge, getting the direct value, let's say the force, is already on the water is not that easy. But for the water, we have more control kind of environment than the second part. And also there's less things we can fine-tune about it. It's mostly about changing your body position instead of those external equipment compared to the bike. In the bike, there's a whole bunch of studies on these things, the bike equipment, the positions, etc.

indoor our outdoor track? indoor is a more controlled environment

Indoor track

imagine those athletes on today's technology. Not fair comparing times from the early 90s to 2020s right?

yes. It is on the list, a very long list.

you have a good eye. A couple of things. The tests were done over 3 days. This was day 2. Day 3 had no wind. Wind speed and yaw were always measured and their impact interpreted in the report for Lionel. Yes, some of those inter day gains were yaw related. At the end of the day, these tests simply guide him to other tests. Multiple road tests in race simulation will confirm the progress he made.

This is a very good question, so when you have a yaw angle involving hair you're arguing essentially it's reducing the drag as they become more streamlined and become more efficient. But I don't know, because the measurement, I believe he's using the Pitot tube or some sort of similar equipment to measure the wind speed at his hand, so that measurement is just the velocity that is in line with his body position. For the power meter, it doesn't have any influence on how much power you're generating in different Yaw angle case. I'm not sure this is inherent features of this Yaw and Go. I believe there's still literature about how those things should be considered properly.
