Webber backs gearbox change over conspiracy theories

Mark Webber is not promoting any of the conspiracy theories after losing his championship lead in Canada last week.

After their infamous Turkey crash, the Australian qualified ahead of his Red Bull teammate Sebastian Vettel in Montreal.

But he had to move back five grid places after a precautionary gearbox change.

Some pundits joked that Dr Helmut Marko, who allegedly favours Vettel, must have taken a crowbar to Webber's transmission.

"I would also have changed the gearbox," the 33-year-old is quoted as saying by Germany's Auto Motor und Sport.
