MONT VENTOUX, France (Reuters) - Chris Froome lost his Tour de France overall leader's yellow jersey after an incident involving a motorbike left him without a bike in a chaotic finale of the 12th stage on Thursday.
The Briton's bike was broken in a pile-up when Richie Porte collided with a TV motorbike close to the finish and the Team Sky rider began running up the slopes of the Mont Ventoux before grabbing a service bike which did not work.
Froome was then given a spare Team Sky bike on which he completed the 178-km stage, losing over 1:30 to his main rivals.
Belgian Thomas De Gendt won the stage.
