Atherton wasn't happy that Moseley used a skinsuit, which being much more aerodynamic than loose clothing, would have given her an advantage.
"Fair enough to Tracy if she wants to do that to win, but for the sport and the longevity of the sport, to wear cool race kit and to make an image for yourself is more important than the odd win here and there," said Atherton.
