Orica-GreenEdge rider Brett Lancaster quit the Tour de France Monday near the halfway stage of the 158.5 km 15th stage from Samatan to Pau, race organizers announced. Orica-GreenEdge, Australia's first elite level professional team and making their race debut, are now down to eight men for the remaining five stages. Lancaster had spent the past two weeks trying to help Australian compatriot Matt Goss claim his maiden Tour de France stage win.
