The results of the Tour de France could have been quite different if certain teams had played the card of technical innovation. This is the feeling of the boss of a crankset manufacturer on the verge of bankruptcy…
Tadej Pogacar will have tried everything. But distance in the climb of the Granon on the occasion of the first high mountain stage, the Slovenian will never have managed to overthrow Jonas Vingegaard despite his repeated attacks. In the end, the Dane was even going to drive the point home in the last Pyrenean stage then in the final time trial. But according to Jean-Louis Talo, the creator of the Osymetric oval chainring, the situation could have been totally different if the leader of the UAE Emirates had raced with his crankset.
Like the Slovenian, David Gaudu could also have aimed for better than his fourth place by being equipped with his system, once adopted by the Sky of Bradley Wiggins and Christopher Froome and still used by the quadruple winner of the Tour. “If you equip David Gaudu with an Osymetric chainring, he is at least second in the last Tour de France. Same for Tadej Pogacar, he would have won without a shadow of a doubt, he told Cyclism’Actu. Chris Froome is the only one still using Osymetric trays and I hope he will win a stage in the Vuelta.
Racers prefer their salary to victories
But against Shimano, the benchmark in the field, the fight is unequal. “It’s not taking off because on this market, there is a Japanese monster whose name I won’t mention (ed. Shimano) which monopolizes 85% of the world market and it’s impossible to be able to move forward on this market! It’s the computer equivalent of Google.”he regretted, adding: “I’m already giving the equipment, I can’t add a check like Shimano does, which gives the equipment and also writes a check. I understand team managers and riders who prefer their salary to victories. »
Jean-Louis Talo can rely on certain studies to prove the effectiveness of his system. “Last May, a study came out of the University of Montpellier which showed that O’symmetrical chainrings had a positive impact on cycling performance compared to circular chainrings. Another should come out by the end of 2022. And I’m not the one behind these studies so I can’t do more to convince, can I? », he assured. And this before detailing its innovation.
10% power gains
“The present study carried out on a population of cyclists of all levels demonstrated that O’symmetrical chainrings had a positive impact on cycling performance compared to circular chainrings. Indeed, the results obtained in terms of muscle fatigue, anaerobic and aerobic performance have proven to be significantly superior compared to circular plates, he explained. Deviations of around 10% were obtained on all the tests carried out in the laboratory. The statistical analyzes carried out showed significantly that the O’symmetric chainrings influenced performance in cycling. The powers obtained are on average 10% higher compared to circular plates for lactatemia lower by 21%. A phenomenon mainly explained by the passage of the high and low dead points passed more quickly allowing an economy of the cycle of pedaling for an optimization of this one. »
