Dr. Bridgewood you seem to have missed these champions of the TT: • Victor Campenaerts • Tom Dumoulin • Rohan Dennis • Fabian Cancellara • Chris Froome • Bradley Wiggins • Dan Bigham (New British Hour Record!!!) • Ellen Van Dijk
This looks mostly like a list of people who have put out big power while aero, rather people who dont need to put out much power to do the same speed, because they're more aero. Ellen Van Dijk looked the least aero of the top 3 at worlds this year, due to being a taller heavier athlete.
@@micomrkaic that’s basically what vulgarisation is, not saying it is any good or bad, u just have to do the job urself if u want correct scientific informations
@takotsubo thank you. I def would expect his cda to be near their. Wouldn’t like to judge his power. Def not got big power going by the euros but he can certainly hold it and power to weight seems pretty good too.😂
You also forgot Remco rode straight into a barrier during a TT. You forgot Si Richardson as well, legend has it takes 4 riders + a pro doing a flat out chain gang to topple him. They had to get a pro as the last attempt someone got dropped within a few minutes 🤔
Remcos performances are a testament to how good he is. His position on the tt bike is a testament to his biology allowing his to be in that position and being able to put down power.
Love this TT content GCN keep it up! The UCI desperately needs to change the TT file rules, they are borderline unsafe and prevent a ton of triathletes from competing in UCI sanctioned events (which hurts participation in the discipline overall). Even adding +5cm to each of the measurements for extension length would help greatly and revert back to measuring from the axis of the shifter versus the tip. (The existing rule puts those with mechanical shifting at a disadvantage fit wise compared to electronic)
The answer is easy. Evenepoel. The 60kg boy can TT on par with 85kg beasts. It's not even a question really, he is hands down the most aero on a TT bike.
I wonder what percentage of his aero gain is because he is simply smaller? You could theoretically have a mediocre position (if scaled up), but your small size makes up for it.
@@rob-c. Emma Pooley did a good video on this for GCN a couple of years back. In short, no, small size doesn't make up for it. ua-cam.com/video/upsn5-fGa0s/v-deo.html
The first person I remember with the high hands position was Floyd Landis. I remember him getting told to change his handle bar position moments before the start, and I guess they over torqued them or something because he broke his extensions moments after the start and had to get a bike swap.
Marlen Reusser has bizar high/long aerobars. The front-end of her bike has a unique look, but she won silver at the Olympic TT and again silver at the World Championship so it must be fast.
:-D Connor, the greatest of them all, will have a free day with his family on wind tunnel day. Instead of Connor they just bring an oak tree and lean his bike against it. :-)
You have to include Ashton Lambie....The pursuit. His Position I think is the most aero of them all ;-). Look when he rides with his team, the others seems like tall towers.
Nice work, Ollie, and for these time trials, I'd like to see a sort of anything goes, speedy racers in their wacky machines, low riders or fully faired or combos of everything. It'd be a great spectacle and circus and the UCI could kick back and say, hey, no rules, so don't crank about us no mo'.
Although this might be a relic of the past, I would still rate Chris Boardman’s position on the Lotus track bike as a benchmark in aero position. Would love to know his cDa.
Not a word about former world champion and olympic gold medalist Fabian Cancellara. Yes he retired in 2016, but he had huge success against the clock. Would have been interesting to compare his riding position with today's best time trialists.
@@JThelen1031 yes, Cd is unitless, but it's almost impossible to measure on its own so CdA is what's always quoted (as in the video). And A is for area, which has units.
Best online cannel on earth. All is correct and i do a lot test also. Can you make a clip between some efforts in past vs. Today. Exemapel bordmann do also de hour record in the 56er km. Ganna also. But i compare of since aeroposition and bike bordmann will be the real monster. Mabe also rominger with 55km.
Jan Ulrich - despite being quite tall and strong he had an incredible position on the bike and his TT style probably was the most elegant of all riders
I'm just curious what your thoughts are on Chris Froome and Tom Dumoulin's positions are? Both have had excellent TT results in grand tours and Olympics (which I under stand doesn't necessarily mean they have a good TT position!).
not having ashton lambie on this list is crazy, he is quite possibly the most aerodynamic rider ever tested with a CdA around 0.16. I've heard he can do 30mph at 200 watts from some credible sources.
A talk about most aero positions but missing Dan Bigham Joss Lowden and Steffan Bissiger arguably the 3 lowest CDA in the world right now. I'm guessing this was filmed before Dan and Joss's hour records attempts
1. What about Manon's position? 2. What about a "mechanical doping" in a form of artificial chests and bellies some riders have used recently? PS I enjoy riding on a tandem with aerobars. Took a while to learn how to keep a balance on turns and less than perfect roads, but... ;)
Know what I really don't understand? Why do they have 2 aerobars when they could just have one and clasp one hand over the other? Mine broke once and I did that for months of training and it worked great. Seems like a waste of weight and aero to have 2. Obviously you need 2 pads, but you definitely only need 1 centered bar.
Jan Frodeno had a handle bar like that in the tri battle against Lionel Sanders. Did seem like a very good idea! I think/hope they will be implementing that on the road soon. Did look like a cock though...
Martin Toft Madsen and Dan Bigham are about as good as it gets for men. Joss Lowden has got super narrow shoulders that tuck in very nicely behind her Tempor.
@@mbal4052 not true it’s a balance between drag, power, comfort, confidence and most important fatigue. I have seen many extreme aero positions that where set up in the tunnel completely fall apart in a tt. What you can maintain in a tunnel for 4 to 5 minutes often doesn’t work when your out on the road buffeted by the wind.
A tall guy like Ganna can never be as aero as someone like Lisa Klein or Evenepoel. He has other advantages that make him quick, but that’s not aerodynamics.
This is an incredibly ill informed video. CdA is the product of Cd = drag coefficient and A = area of cross section of the moving object. 1. The units of CdA are square meters. Ollie should know better, since he studied science! If you don't use the correct units for CdA, you don't get the right units for power from the air resistance formula. BTW, some people call CdA "drag area". Get it? Area! 2. More importantly, Ollie lumps together Cd, which depends on the shape of the moving object, and A, which depends on its size. So, Remco's CdA might be small, be he is also a small rider. If Ganna and Remco had the same shape and hence the same Cd (in the parlance of cyclists -- if they were equally "aero"), Ganna would still have a larger CdA, because he is a bigger rider! The fact that Ollie does not discuss this is inexcusable. 3. This is the third major scientific mistake I've found in GCN videos and I'm losing my patience with this sloppiness.
Realy???? the only picture of Roglič is from last years TT in the TDF???? with the TT helmet on a climbing bike in the midle of a climb??? the best climber in the world with so many TT wins...and the olimpic champion.... it's obvious you don't like him, but as a commentator you should be more objective

Was that because of doing it at altitude though, rather than sea level - not to do with being more aerodynamic.

Which barrier? 😂😂😂

Excellent Job Ollie!
Well Roglic still won the Olympics TT and both Vuelta TTs on that same helmet. So it can't be that bad.
Also I gets aero tested al the time at s Dutch university. And the same helmet being used by the Dutch trackriders being quite successful.

No analysis on Quintana? I am surprised...
They are all starting to resemble the Floyd Landis "praying mantis" position IMHO.

The UCI limits how your your extension can be? Good thing I am not a pro.
If you did all time and not at the moment, my guess is Emma Pooley.
