Did Switch From Osymetric Chain Rings Cost Wiggins Power? - BikeRadar
I am in agreement with what Rotor is doing with their Q-Rings, but this guy and O.Symetric's utterly exaggerated shape never made sense to me. This absurd claim threw credibility out for me.The owner of Osymetric, the French company making ovalised chainrings, claims Bradley Wiggins has lost power – and a mental edge – by switching back to standard rings.
Jean-Louis Talo said that Wiggins (Team Sky), who recently ruled himself out of a defence of his Tour de France crown with a knee injury and illness picked up at the Giro d’Italia and who has swapped back to circular Shimano Dura-Ace chainrings, could have lost up to 30 watts since the switch.
Asked if he was trying to recruit more riders to use the equipment, which he claims eliminates the dead spot in the pedal stroke, he said: “For me it’s incredible that I have to spend so much time explaining so simple a thing [the concept].
"I want to open minds, but I don’t want to spend my time trying to convince people to understand,” he said.
This morning, Carsten Jeppesen, head of operations at Team Sky, denied the claim any pressure was bought to bear on Wiggins’ decision to switch back to Shimano Dura-Ace rings.
Jeppesen said: "Bradley has moved away from them because he didn’t feel they were giving him what he was after, it was nothing to do with pressure. A true winner, if he wants something, will get away with it.”
He added: “[There isn’t] any evidence that this gives you this [advantage], so it’s up to the rider’s feel.”
Poor Contador, Cancellara, Tejay, Cav, Nibali missing out on their 30 watts this year.
