According to Franky Adrieu (sp), former Postie and now OLTNV reporter, LA talked with Basso during the climb and agreed to let Basso win. Later, LA revealed he was happy Basso won, because Basso's mother has cancer and LA and Basso had been in conversations before the TdF about that.
"Lance and Basso talked before the finish and it was agreed that Lance would let Basso win. Lance has said in the past that he wouldn’t give out gifts anymore. But Lance has won here before, so perhaps that changed his thoughts."
