The sprint was my topic for my PhD so I was all excited and trying to look into all the little details.“There was a front photo where you could actually see clearly that … the frontal area of Cavendish was much lower than Goss.
So we kind of guesstimated what could have been if Goss was a little smaller or more aerodynamic or anything like that. Caleb Ewan emerged late from the chaos of the sprint, sprinting down the barriers and passing Sam Bennett (Deceuninck-QuickStep) in the final metres to claim the victory. Australian Caleb Ewan timed his effort to perfection to win the third stage of the Tour de France in a bunch sprint at the end of a 198-km hilly ride through the Alpine foothills on Monday.Sam Bennett looked in control but the Irishman had probably underestimated the headwind and settled for second place as he watched Lotto-Soudal fastman Ewan whizz around him to snatch his fourth stage win on the Tour.
“Because again, the thinking after the world championships was at the moment the lowest cyclist or the most aerodynamic sprinter we could think about was Cavendish.“So we started from there, we had a look and then we were saying ‘Caleb, try to go as low as possible. (You can read about both studies in “Basically you’ve got a group doing CFD, a computer estimation; [you’ve got] Paul in Perth doing the actual cyclist; and the wind tunnel …”, he said. “And then the goal … we ask the subject to assume a more forward position and a lower position. He expects that, right now, institutes of sport and national federations are working on teaching their charges how to assume a similar position.Jakub Mareczko (in yellow, far right) is one rider who’s proficient at getting low. After spending more than a year working on it, Ewan publicly debuted the position in January 2016. “All these three groups [were] applying potentially different methods and instructions etc. “The difference is pretty big. “And so we were kind of dreaming: imagine if you can have a more economic sprinter, potentially we could have won that world championship in Copenhagen, which I found exciting at the time.”Menaspa was working with the U23 Australian development team in 2013 and 2014, a team that Ewan was part of. And so we had some fun with some modelling.”Menaspa and his colleagues started testing sprinters in the wind tunnel as early as 2012.“That was the first time that some actual wind tunnel numbers on a practical level confirmed what we expected from some modelling,” Menaspa said. Blocken’s CFD tests showed a 24% reduction in wind resistance, while Merkes’ field tests showed a 26% reduction. As we fight disinformation and misinformation, and keep apace with the happenings, we need to commit greater resources to news gathering operations. Our plans enhance your reading experience. While this particular paper has only just been published, the building blocks for this research go back as far as 2011 when Menaspa was in the early stages of his PhD.“You may or may not remember the Road World Championship [where] [Mark] Cavendish won and second was Matt Goss,” Menaspa told CyclingTips. Mark Cavendish has been getting super-aero for years now, but Caleb Ewan has become the poster boy for the position.
BUSAN, South Korea (VN) — It’s a homecoming of sorts for 20-year-old Australian Caleb Ewan. Perhaps it’s only smaller sprinters like Ewan (165cm), Mareczko (169cm) and Cavendish (175cm) that can fold themselves over their bars aerodynamically, while still maintaining power.
But after reading all three papers, one question stands out: is it possible to produce the same amount of power when you’ve got your head down and you’re leaning way over the handlebars? Then there was research out of Western Australia that did the same but with real-world riders on the road.
The Orica-GreenEdge neo-pro, who was raised in Sydney by … To enable wide dissemination of news that is in public interest, we have increased the number of articles that can be read free, and extended free trial periods. Each rider did a number of sprints in five positions:Menaspa and his colleagues discovered that, in the third position, wind resistance was decreased by 27% — a significant saving.The five positions tested by both riders in the latest study, published in the Journal of Sports Engineering and Technology.Menaspa wasn’t surprised to see that the lower position was more aerodynamic. Joining VeloClub not only supports the work we do, there are some fantastic benefits:It’s pretty obvious: if you can get down low in a sprint, you’re going to be more aerodynamic than if you’d stayed upright. He’s been a sports scientist with Cycling Australia on and off since 2011, he’s been a researcher at Edith Cowan University in Perth, and he’s worked with the GreenEdge cycling team (now known as Mitchelton-Scott).Menaspa is one of the co-authors on this latest study; a study that involves researchers from Monash University, Edith Cowan University, the Australian Institute of Sport and the University of Canberra.
Menaspa won’t confirm whether it was data from Ewan that was eventually used in the published research, but it seems to be a distinct possibility.“You get a subject, you ask them to sprint in what would be their normal or common sprint position, which generally is out of the seat and is kind of upright — whatever is comfortable and normal for them,” Menaspa said. And then in the wind tunnel you actually measure wind resistance, so that tells you what the potential gain is.”Menaspa and colleagues set the Monash University wind tunnel to produce a wind speed of 70kph for the male rider and 60kph for the female rider.
“Probably the gap between gold and silver was less than a wheel. More research will be required to confirm that.One thing’s obvious though: those who are able to get their head down safely and comfortably while sprinting should absolutely do so.Our mission is to bring you the best content in the world that showcases the beauty of cycling in all its glory.
